Like all not new cars that have been removed from the production line a long time ago, second-generation Samaras are subject to minor breakdowns over the years, which, among other things, affect lighting devices. For this reason, many drivers are faced with the fact that the rear lights on their VAZ 2114 do not light up, which can lead to dangerous situations on the road if the problem is not solved in time.

Features of the operation of dimensions on the VAZ 2114

Being the ideological heir of the first generation, the “fourteenth” inherited from it many technological solutions, including external lighting devices. Thus, the dimensions on the VAZ 2114 are located in the corner areas of the body at the front and rear, which, according to technical regulations, are included in the general blocks of lamps and headlights.

At the same time, there are several features that should be noted when describing the side lights on the VAZ 2114:

• on/off is carried out by a button in the exterior light control module;
• when the lights are on, the switch is illuminated by a green indicator diode;
• The rear lights of the VAZ 2114, unlike the front ones, light up in red, in accordance with Russian road safety standards.

Fuse box

A dedicated fuse block is responsible for the correct operation of the side lamps on this Lada, which can be found in the engine compartment next to the engine. Accordingly, most often motorists who notice non-functioning dimensions on the left or right side of the car are faced with a failed fuse.

The easiest way to diagnose the failure of fuse F10, since it simultaneously acts as a warning lamp, whereas if a pair of dimensions on the left side of the car is not working, fuse F11 will most likely have to be replaced.

CIRCUIT BREAKERS

To protect against voltage surges and other influences on the electrical component, a side light fuse is also included in the circuit along with the light bulbs and the button. At the moment of overvoltage, it burns out, but due to this everything else in the circuit remains intact. It is usually located in the engine compartment, where in the VAZ 2114 there is a place for a whole fuse block for all electrical networks in the car.

Since all of them have markings, we can easily find the parts that we need: F10 is responsible for the safety of the lamps on the left side of the car, and F11 for the right. Thus, in the event of a failure of one half, for example, when the rear left indicator does not light up, the right side of the car will remain operational and will do its job. And if the size fuse blows, then replacing it is, in principle, quite simple - this is considered the simplest malfunction of this kind.

Causes of malfunctioning rear lights

Troubleshooting a situation with non-working side lights is the primary task of the car owner, as this not only creates a dangerous situation on the road, but also, in the end, is fraught with a fine from the traffic police.

To find out why the dimensions of the VAZ 2114 do not light up, you need to focus on three main factors:

1. Burnt out lamp.
2. Loose contact of the power wire.
3. Broken wiring leading to the gauge.

Working rear dimensions

The first case is the most common, and the problem is solved by simply replacing the light bulb, fortunately, they are sold everywhere and cost little money.

You can confirm the second reason without disassembling the device by simply tapping on the size: the moment you press it to the contact, the lamp will light up, and vice versa, it will go out in the free position. If disassembling the device did not reveal any oxidation with carbon deposits, a burnt-out lamp or a loose terminal, but the rear marker of the VAZ 2114 still does not light up, we can talk about faulty wiring.

TROUBLESHOOTING AND THEIR REMOVAL (REAR AND FRONT DIMENSIONS)

Now we just have to figure out why such problems occur and how to solve them, for example, how to replace a side lamp on a VAZ 2114 in any part of the car. So, first of all, let’s figure out why the lights don’t light up and what reasons there could be for this:

• No voltage on headlights;
• The lamps are burnt out;
• The fuse has blown;
• The fuse box has failed;
• The button to turn on the lights is broken.

So, now we need to understand each specific option in more detail, for example, why the left rear light does not light up. The first and most logical reason is that the lamp simply expired and burned out, just as happens with ordinary household light bulbs. Now it needs to be replaced; this is done in the same way in all parts of the car:

1. First you need to find where the headlight housing or collar housing is located from the inside and remove the protective cover; on the VAZ 2114 it is clearly written on it how this is done. Everything will come out together with the base;
2. Now you need to find the size in the base and carefully pull it out;
3. We take out the lamp, it is simply inserted here with a latch;
4. We insert the new one so that it clicks and assemble everything in the reverse order.

As for the fuses, if the rear right indicator light does not light, then in order to do without special tools and diagnose the cause, you just need to replace the suspicious fuse with a new one and see if the situation improves. If the lamps light up, then it was the problem, but if not, then you will have to look for the cause further. The tail light is always off. A very weak point is a design flaw in the contact group in the headlight.

To understand why the rear lights on a VAZ 2114 don’t light up, you need to look at the car’s electrical circuit; power to the lights goes along with the headlights, and if they don’t light up only at the front or rear, then it’s the wiring. It will have to be checked, but without the special knowledge of an electrician, it is unlikely that you will be able to find an open circuit or some other reason on your own. But if the right indicator light on a VAZ 2114 or only the left one does not light up, then it’s all a matter of fuses, replacing them is simple - take out the old ones and insert new ones in the same place. Checking the button is also quite simple - you need to remove it from the panel and short-circuit the wires; if the lamps light up, then it’s the problem. You will need to find a new button that will fit there and install it.

Replacing a broken light bulb

To repair the rear lights of a VAZ 2114, you need to follow a number of simple recommendations:

• turn off the vehicle's power supply;
• open the trunk, remove the decorative trim;
• Squeeze the latches and remove the contact panel of the entire flashlight;
• press down the faulty lamp and turn it counterclockwise to remove it.

Replacing a light bulb in dimensions

Next, it is advisable to “ring” the lamp with a tester to make sure that it was its malfunction that was the cause of the problem, after which it should be replaced with a new analogue, and you can begin assembling the lamp in the reverse order.

Some Lada owners, faced with the fact that the dimensions on their VAZ 2114 do not work, do not bother and change the entire headlamp assembly - especially since they are not so expensive. This can be considered a convenient solution, since such a replacement eliminates for some time the possibility of failure of other lamps in the flashlight, in addition to the marker lamp.

In some situations, the breakdown of the dimensions does not represent a complete non-functionality of the lights, but simply a weaker glow, which indicates a problem with the supply of current to the contacts. To fix the problem, it is enough to clean the entire contact group in the control unit under the hood, and if that doesn’t help, you will have to check each group leading to the rear light separately.

Why might the tail light not light up?

Not a single motorist is insured against faulty side lights. It is important to quickly understand what the reason is and carry out repairs. Most often one of the lamps fails, then we can assume the reason for the failure:

• she burned out;
• poor contact;
• breakdown in the wiring leading to this lamp.

The first occurs most often; in this case, it is enough to replace the failed lamp. If the lamp only works if you hit it, then there is a problem with the contacts (although physical impact does not always help). If during testing you find that the light bulb is intact, and there is no oxidation or carbon deposits in the socket, then you need to check the conductors.

Replacing a damaged lamp in the rear headlight unit is carried out according to the instructions:

• turn off the lights and open the trunk;
• remove decorative upholstery;
• squeeze the latches and pull out the flashlight contact panel;
• click on the burnt out lamp and turn it counterclockwise;
• Check the light bulb on the tester and install a new one if necessary.

Assembling the lanterns is carried out in the reverse order. The lamp can also be replaced as an assembly. To do this, it is only important to purchase a high-quality version that is no different from the original. Car enthusiasts often recommend purchasing stock components or paying attention to. We recommend replacing the assembly if there is significant damage to the structure.

Additional Tips

Sometimes VAZ 2114 owners are faced with the opposite situation, when the rear lights themselves work, but the indicator on the power button does not: this is almost always a sign of a faulty wiring in the interior panel. You can deal with the problem by removing the entire key block and thoroughly wiping its contacts.

In general, the side lights on this VAZ model should not often fail, since the contact pads for their fuses were specially increased in width in order to ensure a tight connection.

In addition, experts advise that in frequent breakdowns of dimensions there is a malfunction in the mounting block itself or its electrical circuit. Such a problem must be eliminated as soon as possible to eliminate the risk of a wiring fire.

Finally, you should pay attention to the tightness of the entire rear light unit and prevent moisture from getting inside, which can easily cause the lamp contacts to sour.

Replacement process

The rear lights are attached to the body of a VAZ 21099, 2108 or 2109 car using 4 nuts. To dismantle the lighting system you will need:

The operating algorithm is as follows:

• To access the nuts, remove the 21099 luggage rack at the appropriate location (if the rack is installed).
• Disconnect the power plug that is attached to the board.
• Unscrew the 4 nuts using a wrench.
• When removing the last nut, hold the taillight outside to prevent it from falling and breaking.
• After removing all 4 nuts, remove the light.

When installing a new headlight on the rear of model 21099, do not forget to connect the wiring to ground, which is attached to one of the studs.

In such cases, the ride becomes quiet, calm and relaxed, but how everything changes when at least one light bulb burns out. This causes inconvenience and emergency situations, and you can also get a fine from a road service employee.

The dimensions on the VAZ 2109 do not light up, then look for the reason in the wiring. Even experienced drivers recommend carefully checking the functionality of all devices and components before leaving. The nine is no exception, in which optics can often fail for various reasons, including:

The rear lights (headlights) of the VAZ 2108, VAZ 2109, VAZ 21099 have the following bulbs: 1) Brake lights. 2) Dimensions. 3) Reverse. 4) Turns. 5) Fog lamp.

Rear light board for VAZ 2108, VAZ 2109, VAZ 21099

A wiring harness goes from the mounting block to the rear lights. The purpose of each individual wire in the harness can be understood by its color: 1) Brake lights - red 2) Dimensions - yellow 3) Reverse - green. 4) Turns - blue. 5) Fog light - orange-black.

We remove the connector from the rear light board of VAZ 2108, VAZ 2109, VAZ 21099

Naturally, you need to understand that if the car VAZ 2108, VAZ 2109, VAZ 21099 is old and there are a lot of people doing the wiring, then the color match of the wire to its purpose may be violated. That is, the red wire can be converted not to brake lights, but, for example, to dimensions. But in general this is a very important point: the developers of the VAZ 2108, VAZ 2109, VAZ 21099 specifically marked the functional purpose of the wires with a certain color to make it easier to use.

If some light signal in the taillight of a VAZ 2108, VAZ 2109, VAZ 21099 does not work, then before climbing into the mounting block and opening the electrical circuit, we check the following: 1) The reliability of fastening the mass of the taillight to the body of the VAZ 2108, VAZ 2109, VAZ 21099.2)

We check the reliability of fastening the wire connector to the headlight. 3) Integrity of the light bulb 4) Quality of contact between the light bulb and the flashlight board. It often happens that everything is intact, the light bulb and the mass are good, and 12 Volts come to the light bulb, but it does not light. The reason is poor contact between the light bulb and the board. In this case, you need to clean both the light bulb base and the area on the lantern with fine sandpaper.

As one smart person said: “Electrics is the science of contacts.” To disassemble the rear light of a VAZ 2108, VAZ 2109, VAZ 21099, first remove the protective plastic cover. Then disconnect the black wire of the flashlight from ground. Then we remove the connector from the flashlight board and remove the board itself with the bulbs from the headlight housing. If it is necessary to replace the headlight itself, then unscrew the remaining bolts securing the headlight to the car frame and remove it.

Malfunction of LED brake lights

If, after carrying out the measures described above, it is not possible to determine the reason why the brake lights do not light, you should clarify the type of lamps used. They can be made using LEDs. Their installation has a number of features. Typically, LED lamps have a certain polarity for connecting to the vehicle’s on-board network.

Manufacturers always take this into account when developing. Incorrect connection results in the lamp not lighting up. In some cases, such inclusion may lead to damage. If a connection polarity violation is detected, this indicates that the repair on the vehicle was carried out by an unqualified person.
