The Ford Focus 2 restyling heater does not heat well

After reading a couple of hundred articles, I still haven’t found a specific answer. In all the articles, the fan does not turn only at 123, but turns at 4, and in this case the heater fan resistor is to blame, but in my case it does not turn at all.

Fuses F10, R10 are working... The motor itself is also working - I removed it and checked it directly.

What could be the problem?

Another quick question: is the VAZ 2107 solenoid valve suitable for my FF? Some people on the Internet tried to install it and did not complain.

Ford Focus II, 2008, 125 hp, 1.8 M, restyling

Hello everyone, in this short article + video I will try to tell you in as much detail as possible how to independently change the heater motor (fan) on a Ford Focus 2 car. I have a pre-restayl, the restyles seem to have a similar scheme, although the final codes for the engines are different for some.

It all started when the stove started creaking. This didn’t bother me much; last year it squeaked when it was cold and after warming up the squeak disappeared. This year, creaking began even when it was warmed up, and there were no severe frosts, but it creaked... And on one not very frosty (and warm enough to drive without a stove) morning, it stupidly did not turn on. Or rather, everything turned on, except for the fact that it was blowing... The only thing that saved me for moving was that I had a heated windshield, and also that even though the heater wasn’t working, there was a slight breeze through the air intakes when moving, which prevented the windows from fogging up.

To begin with, I studied several manuals, articles, and so on, and was already desperate and wanted to take the car to a service center, because... I couldn’t find the cause of the problem myself... In general, I decided that since I was taking the car to the service center, I might as well try it myself, if they fix my problems, I’ll go for a walk =)

In the manuals, everyone describes the complete removal of the panel with the removal of the stove, in the video I’ll tell you how to do without this...

In general, first remove the glove compartment and fuse box

Remove the gas pedal

Next, disconnect the chip from the engine and begin removal...

This is essentially what was not included in the video...

Ford Focus 2 heater does not heat well

It also happens that the stove still works, but blows cold air, or even produces a temperature that is insufficient to warm up the interior. So, let’s try to figure it out and find the reasons why the stove does not heat well:

Coolant does not circulate well in the system. Perhaps its level has dropped as a result of a leak, or the “coolant” has exhausted its service life, or an air lock has formed somewhere. In any case, it is worthwhile to inspect the engine cooling system; be sure to check and add antifreeze to the required level or replace it altogether if quality indicators deteriorate;
The thermostat or temperature sensor is faulty. There is no way to do without replacing these parts;
improper air circulation due to violation of the correct position of the thermostat valves. This leads to the fact that the cooling liquid circulates only in a large circle, as a result of which cold air does not enter the heater radiator;
Too much debris and dirt has accumulated in the heating system, which interferes with its normal functioning.

As you can see, the reasons for the lack of heat in the Focus’s interior are largely interrelated. By the way, the restyling of the model has the same problems.

Finding the cause and eliminating it

Indeed, it happens that after starting the engine, instead of the expected warm air, cold air begins to actively flow into the car interior, at least barely warm. Of course, not only does no one want to put up with such a problem, but also will not from a security point of view. If the supply of warm air is poor, it is impossible to eliminate icing on the glass. As a result of limited visibility, driving a vehicle is much more difficult; for this reason, you can find yourself in various unpleasant situations, including emergency ones.

Faulty thermostat

Some car owners of this vehicle also observed such a picture when the stove flatly refused to function normally, but after covering more than 50 kilometers, and then the subsequent complete cooling of the engine, the owners successfully started the stove, which provided a quick supply of warm air.

Masters suggest using one secret if the stove fails after starting the engine. You should step on the gas and try to keep the engine speed at two to three thousand for some time. As a result of such cunning manipulations, the stove will delight you by resuming its functionality, providing a supply of warm air.

If you managed to force the stove to blow hot air using these actions, then the problem lies in a faulty thermostat. It is best to simply replace it, preventing failure of the entire heating system.

Additional reasons

However, not only a faulty thermostat can cause a malfunction of the stove. There are some other reasons that negatively affect the performance of the heating and ventilation system. These include:

insufficient circulation of antifreeze;
faulty fuse;
faulty fan relay;
penetration of foreign objects into heating pipes.

Indeed, during active vehicle operation, fallen tree leaves, fluff, dirt, and other debris enter the heating pipes. It is these third-party objects that block the passage of warm air. Accordingly, it is simply impossible to warm up the car interior normally. Of course, everyone understands that solving this particular problem is as easy as shelling pears. It is enough to free the pipes from debris, and the stove will instantly begin supplying fast hot air.

The vehicle owner is obliged to monitor the antifreeze level. If its level is lower than prescribed by the manufacturer, the heater will simply be unable to operate successfully. Antifreeze, which the owner has not changed for a long time, can also cause a failure in the supply of warm air. Over a sufficiently long period of time, antifreeze changes its characteristics and loses its basic properties.

Many experts recommend taking the time to completely clean the system, removing any traces of contamination. After such cleaning, be sure to pour new antifreeze into the system. The car will definitely please you with its work for such a sensitive attitude and attention to itself.

Replacement of components

Unfortunately, sometimes you have to resort to purchasing new parts and elements, exposing yourself to additional financial expenses, which in some cases cannot be excluded.

Often the stove does not want to supply warm air because the fuse has blown. Of course, in this case you have to purchase a new fuse, then open the block on which they are located. Find the burnt element on this block, remove it, and install a new fuse in its place.

However, it is not only the fuse that can cause you such inconvenience. Sometimes the fan relay fails. You can find the relay in the same place where the fuse box is located. To check the functionality of the relay, it is important to have a tester, which is a special device that can be used to determine the condition of many devices. Even if the tester demonstrates the working condition of the relay, some experts recommend replacing it and trying to start the stove. Of course, if the tester shows that the relay has failed, then there is only one option for further action - be sure to purchase a new relay.

Sometimes all the actions described above do not lead to the desired result. In this case, the cause of the malfunction should be sought in the stove itself. The resistor in it may fail, so the entire unit will need to be replaced. The electric motor of the stove itself may also burn out, then you will need to carry out a high-quality repair of it or purchase a second one in working condition and install it in the car.

The Ford Focus 2 heater fan does not work. How to remove it?

Quite often this element of the car heating system fails. Sometimes you have to listen to how terribly its bearing whistles. Nerves simply give out and the responsible car owner begins to look for ways to remove this problematic part?

It happens that when the first, second or third position of the switch is turned on, the fan does not work, starting to start only in the fourth mode. This failure is caused by the failure of additional resistors.

We begin to remove the stove fan.

You can get to it only after removing the glove compartment. After that, you need to remove the right air duct, remove the power supply wires from the electric motor terminals and, unscrewing the fastening screws, remove the fan.

Causes of poor stove performance and ways to eliminate them

If after starting the engine about a quarter of an hour passes, but the interior of your Ford Focus 1 does not warm up, it means that you really had to face the problem of poor operation of the stove.

Various reasons can provoke such trouble. It is enough for just one element of the heating system to fail, and normal heating of the car interior becomes impossible.

A non-working fan, an excessively low level of coolant, a dirty heater radiator, a faulty thermostat and pump - this is just a small list of reasons as a result of which the heater begins to blow very weakly, so the interior will be constantly cold, and frost will remain on the windows.

Algorithm for troubleshooting

Due to the fact that various reasons can provoke the problem of poor heating of the interior of a Ford Focus 1 car, we offer you an algorithm of actions, following which you will definitely be able to identify the problem. Initially, we recommend that you check the coolant level. If the level of antifreeze or antifreeze is low and does not meet the requirements set by the car manufacturer, then the ventilation and heating system will be unable to function properly.

The coolant level may drop due to a leak, so we recommend that you check the integrity of the pipes through which the liquid flows, as well as the radiator. If even a minor leak is detected, you cannot leave everything as is, pushing back the date for repair work. Even the slightest leak provokes the penetration of air into the system, and after this, so-called air jams appear in the system, preventing the supply of warm air to the interior of your car.

A problem may also arise when oil suddenly penetrates into the container where antifreeze is poured. This situation occurs when the engine head gasket is completely worn out. In any case, you will have to flush the system and fill in new antifreeze or antifreeze. You can even check and determine the true cause yourself. In particular, it is recommended to accelerate the car to maximum speed and keep it in this state for at least 15 minutes. After this, see how the liquid behaves.

How to remove the heater motor?

In principle, as experienced auto mechanics say, this task is not so difficult as it is painstaking, since most of the work has to be done by touch.

Therefore, when starting the process of removing the heater motor, you need to be patient and do everything in the described sequence:

It is necessary to remove the glove compartment by unscrewing the seven fastening screws.
Remove the cover of the module in which the fuses and the unit itself are located.
Remove the power wires from the recirculation damper.
After disconnecting the clip, the insulation must be removed.
We unscrew the fastening and pull out the damper, first removing the remaining old grease with a rag.
Remove the wires from the motor terminals.
On the driver's side, on the fan housing, there is a lock. It must be felt and pressed towards the center, after which the body can be turned counterclockwise without effort. If possible, it is necessary to lower the damper down as much as possible, after which the motor is moved to the upper right part.
Pull the motor out through the window formed after removing the fuse box.

Install the motor in the reverse order, and apply lubricant to the recirculation flap.

Replacing the heater resistor

A T25 TORX wrench is required to perform this procedure. Note that the sequence for replacing the heater resistance is the same for Ford Focus 2 and its restyled variants.

First you need to disconnect the negative cable from the battery terminal. Next, remove the accelerator and brake pedal control unit and disconnect the wires suitable for the resistor. Using a TORX T25 wrench, unscrew the mounting bolts and remove the heater resistor.

Everything is assembled in reverse order.

Replacing the stove radiator

We will describe the process of replacing the heater core without removing the dashboard.

First you need to remove the center console, disconnect and remove the air ducts that supply heat to the rear of the cabin. Carefully, so as not to damage the latch, remove the lower part of the trim (semicircular plastic from the front panel). After unscrewing the bolts located under the trim, you need to remove the metal corners. Both parts of the lower section of the stove body must also be removed. To do this, unscrew the fastening screws and carefully bend the latches. We remove the glove compartment and both air ducts, after which we disconnect the heater housing, along with which the radiator should appear. This is not so easy to do. To facilitate this process, it is necessary to slightly bend the torpedo stiffeners towards the side. It is necessary to disconnect all hoses from the radiator, and then remove the heater housing along with it. After repairing or replacing the radiator, assembly of the unit is carried out in the reverse manner.

Basic faults

The list of the most common causes of stove failure and lack of heat in the cabin includes a fan malfunction. Perhaps the stove is not working due to a fuse, but there are no problems with the mechanism. This is where you need to start checking. We open the fuse box (it is located on the left side of the engine compartment) and find the element we need. To do this, you can use a special scheme. The fuse is responsible for the safety of the entire heating and ventilation system, and therefore its failure can lead to failure of the stove.

If the fuse is OK, you need to look further. The fan relay, which is located in the same block as the fuse, may have broken. It is checked with a special device - a tester, to which the relay is connected. If it is not there, then you need to take a working relay and install it in the socket. The problem with the stove was resolved, and the fault was discovered. If the Focus 2 heater fan still does not work, then you need to look further and deal with the electric motor itself.

Getting to the electric motor is quite difficult, but we will tell you how to do this a little further. When the motor is in your hands, it needs to be checked. To do this, connect directly to the battery and listen to see if it works. If not, you will have to replace or repair it. If it works, you need to look for a fault in the wiring or in the control unit.

In some cases, the stove operates in only one of the modes. As you know, you can choose 4 speeds, and the higher it is, the more intense the airflow will be. Quite often the fan only works at the highest speed, and nothing happens at all other speeds. As a rule, this means a malfunction of the resistors, which are placed in a separate unit. If one of the resistors fails, you will have to replace the entire unit, which is located under the glove compartment.

So, these are the most common reasons for stove failure. Note that you can fix the problem yourself if you have a garage where you can remove the engine or deal with other problems. If this is not possible, then you can contact specialists who will quickly detect the breakdown and carry out repairs.

The heater on a Ford Focus 2 car does not work. What should I do?

With the onset of cold weather, two systems are responsible for maintaining a comfortable temperature inside the Ford Focus 2 car:

cooling of the power unit;
ventilation and heating.

Therefore, if the stove does not work and warm air does not enter the cabin, the cause of the breakdown will have to be looked for in them.

The most common reason for the lack of heating in a Focus is a blown fuse F10 (30A), which is located in the climate control fan circuit. In the fuse box it can be found on the left side. The diagram will indicate its more precise location.

If everything is in order with the fuse, you should pay attention to the fan relay, which is also located in the fuse compartment. It is more expedient to check its serviceability using a tester, after first removing the relay from the socket. However, a more effective method of checking is using a new, serviceable relay, which is installed in the socket instead of the old one, after which the heater fan starts. If it works, then the cause of the problem has been identified. Otherwise, it is necessary to check the operation of the fan electric motor. In addition, there are a number of malfunctions that should not be overlooked.

The process of removing the electric motor

Generally speaking, it is not difficult to get a stove motor and almost everyone can do it. However, the problem is that making withdrawals is very inconvenient and you have to do a lot of things blindly. If you decide to repair it yourself, then you need to be prepared for inconvenience. Removing the electric motor is carried out as follows:

unscrew the bolt securing the glove compartment and remove it from its regular place;
remove the fuse box, first removing its cover;
disconnect the wire that connects to the recirculation damper;
pull out the clip and remove the insulation;
remove the damper from the mount and remove the old grease with a rag;
disconnect the power wires of the electric motor;
on the driver’s side there is a lock on the body that needs to be released by pressing it towards the center;
turn the electric motor counterclockwise and pull it out to the right side;
We remove the motor through the place where the fuse box was located and check its functionality.

Checking the Ford Focus 2 electric motor

The previous steps may not have been useful, and the heater fan on your Ford Focus 2 still does not work. You should move on to looking for faults in the electric motor. To dismantle this part, you will have to dismantle other components. So, you should remove the bolt securing the glove compartment. After this, the fuse box and the cable connected to the recirculation flap are taken out. Next on your way there will be a clip that needs to be pulled out, along with the insulation.

We're almost there. We remove the damper from its place, then carefully pull out the cables that provide power to the electric motor. In the freed space, on the left, you will find a latch that can also be removed.

So, the electric motor has been removed and you can check its functionality. To do this, connect the unit to the battery. If everything works, this indicates that the problem needs to be looked for in the wiring and control unit.

If connecting to the battery did not start the electric motor, it means that the heater motor on the Ford Focus 2 stopped working precisely because of this unit. In some situations, the electric motor is subject to repair, but these actions can only be performed by a professional specialist.

There are situations when everything is fine with the fan, but only at the fourth speed, with a strong supply of warm air, and at any other speeds the fan stops. In this case, the failure lies in one of the resistors. Alas, it won’t be possible to replace just one part; you will have to completely change the entire unit.

Poor stove performance

In some cases, the stove works on a Ford Focus 2, but it does not heat well enough or blows cold. This means that it does not fulfill its functions. As a rule, there are several reasons for this problem, including:

Comfort in a car depends on many different factors. During the cold season, it is almost impossible to move without a stove. On a Ford Focus, the stove works great and allows you to warm up the car interior quite quickly. However, for various reasons, this system may fail, and it will not cope with its work. What to do if the heater on a Ford Focus 2 does not heat well? What are the main reasons? Let's find out.

Most often, Ford Focus 2 owners encounter the following problem. After starting the engine and warming it up to operating temperature, cold or barely warm air blows. There are no errors, and everything seems to be working correctly. It is noteworthy that after some time the problem can resolve itself. For example, after driving 50-100 km and letting the engine cool completely, the next time you start it, everything will work fine.

You can try to solve problems on the spot. To do this, you just need to press the gas a little and maintain the speed at 2-3 thousand for a while. After this, the stove should blow warm air again. In this case, the problem lies in the thermostat. For some reason, it either opens a little or closes. In the second case, only a small circle is heated. The problem can be corrected by replacing the thermostat. After the repair, hot air will always blow, and for this reason the heating system will not fail.

Ford Focus 1 heater motor repair

I'll tell you how I repaired my heater motor. The problem was that the brushes were worn out and the motor simply did not turn. I had to buy a new motor, and its cost due to my climate control was 20,000 (not a small amount) - it became a pity. I went to the store to buy a regular motor for a focus without climate control, I draw your attention to the fact that it costs 5,000. There is a difference. Progress of work on repairing the Ford Focus 1 heater motor

1. We take two motors: the right one is original, the left one is purchased.

2. Remove the top covers of both

3. We remove the wires from the covers, this is done quite easily, there is a special latch that holds them 4. And using the same method, in reverse order, we simply change the motor covers, and a new ready-made motor will cost only 5 thousand.

Conclusion: saved 15,000 rubles. Now everything works great, even better than before the breakdown.

Replacing the heater fan for Ford Focus 1

Some time ago, I lubricated the stove fan and, while doing this procedure, bent the brush holder too far. After driving for a week with the heater lubricated, I went to the car wash and after leaving it, the windows began to sweat, and I turned the heater fan to maximum. Almost immediately I heard a hum with vibration in response and after 4-5 seconds silence in the area where the stove was located. When I got home, I immediately removed the fan and took it apart to disassemble it. An autopsy showed that the brush on the engine had come off. I put it in place and tightened the spring. Having put the fan in place, to my surprise it did not work. I started searching further and got to the fuses in the engine compartment and found a burnt-out pre at 30. I replaced it, the heater started working, but after 10 seconds it went silent again. My sadness knew no bounds. Having removed the fan, I decided to buy a new one and stop sweating. I ordered it online and this happiness came to me:

After installing it, everything worked without problems, and still works to this day.

Note: when lubricating the fan, do not bend the brushes, and if they do, make sure that the spring has not weakened!

as you can see in the photo the brushes are alive

Replacing the Ford Focus 1 heater light bulbs

Since the purchase, 2 heater light bulbs have not been lit. Everywhere their replacement is considered difficult, but this is not so. The work took about 20 minutes. Instead of the relatives, I installed white LEDs. Replacement procedure: 1. Remove the radio.

2. Pull out the plug above the radio (pull it towards you, bending the antennae)

3. Unscrew the 4 screws in the corners of the window for the radio. Be careful not to drop it. 4. Now we take out the ashtray and the center console is held in place only by clips. 5. Pull the console from all sides with a little force, it should give in. 6. Unhook the connectors for the cigarette lighter, emergency lights and clock

. We see 4 sockets, turn them and remove the bulbs. 8. replace with new ones, assemble in reverse order.

In total there are 4 light bulbs, the price of one LED is 10 rubles. I liked the result, the colors are bright, I plan to change it in the tidy in the future.

Cleaning the Ford Focus 1 heater radiator

When I got the car, the heater was quite slow: the engine had been warming up for a long time, and only warm air came out of the heater. Really hot air only started flowing after about 20 minutes of driving.

I read Focus Club, many people have this problem. I started studying the mathematical part. I came to the conclusion that the power supply circuit for the heater radiator, although made quite masterfully technically, is very critical in terms of the quality and condition of the components.

Slurry flow pattern:

fluid flow diagram on the right side of the engine

What do we see in the diagram? Both outputs of the thermostat housing, which went forward and backward, are equivalent, and the liquid flows there at the same time.

At first glance, this scheme is complete nonsense: we have 2 branches running in parallel: a short one, in front of the engine, and a long one (about 1.5 m of hose + heater radiator) - behind the engine. At first glance, all the slurry should go along the front branch; its resistance is much lower. But it's not that simple. To understand the whole focus of this unit, look at the large photo of the connector above the radiator, and where it all is connected.

connector above the radiator

The far right hose on it is a straight short branch from the thermostat. The hose to the left is from the stove.

What do we see here? the right branch is narrowed, and the second branch from the stove is inserted into this narrowing. Those. in front of us is a typical ejector. How does it work? The liquid from the thermostat, moving along a straight and short branch, creates an intense flow in the pipe. Moreover, its cross section is specially narrowed here, and the speed of the liquid increases. And the flow of slurry from right to left pulls the slurry out of the stove hose. In much the same way as the air flow in a spray gun draws paint out of the container.

Those. Initially, the technical solution is very beautiful. But, unfortunately, such a system is not very resistant to the aging of components: as the radiator branch of the stove becomes dirty, it becomes harder and harder to pull the liquid out of it. At some point in time, the liquid begins to move only with a strong over-throttle of the engine. And at some point in time, the slurry finally rises.

There is another problem here. The long plastic connector above the radiator is initially not particularly reliable, and for many it leaks through the connections.

At the Focus Club, people made homemade units from steel, stainless steel, and polypropylene. The only thing is, when making a homemade assembly, it is important to understand that this is not a stupid tee, and not to make it from one pipe of the same cross-section, no matter how tempting it may seem. You need to understand that there is an injection core unit, and you need to make it too.

On my car this connector was removed by the previous owners. Instead, a blunt short tee was installed. Apparently they had no idea that the standard unit was not just a tee. It is not surprising that the effect of pulling liquid from the stove branch, which was not particularly strong anyway, disappeared almost completely.

Main reasons

So, we have already talked about several malfunctions that lead to poor operation of the stove. What other malfunctions can occur that affect the operation of the interior heating system? The main reasons why the stove does not heat are:

poor circulation of antifreeze in the system;
a large amount of debris, leaves, dirt and other foreign objects in the heating pipes, which prevents normal heating of the cabin;
blown fuse;
Fan relay malfunction.

Let's take a closer look at each reason.

If the level of antifreeze in the system is below normal or it has already lost its properties, then the stove will not work well. Also, the formation of an air lock can lead to a low temperature of air flows from the stove.

First of all, you need to add coolant to the normal level. If this does not help, then the reason for the poor performance may lie in another problem.

For example, severe contamination of the system leads to the fact that the air will heat up very little. Let's say you cleaned everything, but it didn't bring any results. Note that the second Focus in the restyled version has the same problems.

Go ahead. Often there is no hot air for a trivial reason - the air conditioner fuse has blown. To replace it, you need to open the fuse box, remove the faulty part and install a new one. However, this is not always the problem.

The furnace may blow cold air if the fan relay is faulty. It is also located in the fuse box. You can check its operation using a regular tester. To do this, you need to remove the relay and perform diagnostics. However, even if it works well, you can try installing a new relay. There is a huge chance that the system will start working well and blowing warm air. If this does not help, then perhaps the problem is in the stove itself: the electric motor, resistor, etc. are faulty.

Ford Focus 2 stove repair: we study thoroughly

The heater does not work on a Ford Focus 3.5. What to do?

With the advent of cold weather, two accounting software (software) are responsible for maintaining a comfortable temperature inside the Ford Focus 3.2 car:

cooling of the unit;
ventilation and heating.

If the stove does not work and warm air does not enter the cabin, the cause of the breakdown will have to be found there.

A more common reason for the lack of heating in the Focus is a blown fuse F10 (30A), which is located in the climate control fan circuit. You will find it on the left side of the fuse box. A clearer placement of it will give a hint from the diagram.

If the passage, if the fuse remains in order for our client, it is worth checking the fan relay, which is also located in the fuse compartment. It is more expedient to check its serviceability using a tester, having previously pulled the relay out of the socket. But, a more effective test method is to use a new, serviceable relay, which is installed in the socket instead of the old one; after completion, the heater fan starts. If it works, it means the cause of the problem has been identified. Otherwise, you need to check the functionality of the fan electric motor. In addition, there are still a number of defects that should not be overlooked.
