Rear lights do not light up on a VAZ 2114, how to solve this problem

Characteristics of side lights VAZ-2114

VAZ-2114 belongs to the Samara modification of the second generation. The side lights in them are located, in accordance with technical regulations, at the edge of the front and rear parts of the body, next to the turn signals. These lamps are included in the headlight units.

1. Unlike the front side lights, the rear ones are painted red.
2. The button to turn on these headlights is located in the exterior lighting control unit. It is located in the center of the dashboard above the on-board computer. If the dimensions are turned on, the green light on the switch lights up.

In the engine compartment under the hood of the car there is a mounting block with fuses. If your lights only on the left or right side do not work, then most likely one of the fuses has failed. The easiest way to notice a malfunction is element F10, since it is responsible not only for the operation of the right side of the side lights, but also for the warning lamp to perform its duties.

If the lights refuse to work on the left side, then fuse F11 must be replaced.

How to enable

Let's start with how to include dimensions. When buying a car, the first thing to do is not study the engine power, but the location of the exterior lighting controls

.

In different cars, control can be performed differently, and you need to clearly know where the lights, headlights, and hazard lights turn on.

In addition, side lights of different brands may differ in design: there may be regular size indicators and light bulbs in the headlights, or separately. In any case, carefully study the service manual for your car and remember the location of the controls.

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.

Often, taillight lamps do not immediately burn out or refuse to work, but indicate problems with a faint glow. First, clean the group of contacts located in the mounting block, and then, if the fault cannot be corrected, check the groups leading to each lamp.

Why the side lights on VAZ 2114 and 2109 may not light up

Side lights are lights that tell other drivers on the road about the size of your vehicle. According to the rules, the driver is required to turn them on in a number of cases. In particular, when the street lights start to turn on and when stopping at the side of the road. This article provides information about why the lights on the VAZ 2109 do not light up. The material will be useful to owners of all generations of Lada Samara cars.

Possible causes of malfunction

1. The lamp is faulty. The most common reason why the rear lights on a VAZ 2114 do not light up is that the lamp in the lamp has burned out. This diagnostic sign is relevant if only one gauge does not work. In this case, it is enough to replace the burnt out lamp. 2. The fuse has blown In the case when several dimensions fail at the same time, the reason for this may be problems in the mounting block, to be more precise, in fuse F10. The breakdown of this fuse often leads to the fact that the dimensions of the VAZ 2114 do not light up. In this case, there may also be problems with the lighting of the interior and license plate lights, as well as the dashboard. 3. The contacts are faulty or oxidized. To exclude this cause, you will have to check the entire fuse box. In particular, you should carefully inspect the bus terminals leading to the fuse and relay box. It happens that they oxidize or become detached and therefore make poor contact. Here you will need to disconnect the contacts, clean them and connect them. If after this the rear lights of the VAZ 2114 or 2109 still do not light up or if there is a problem with the front lights, you will need to check the contacts on the headlight unit. Maybe the contacts have oxidized there. 4. The power button has stopped working. The reason why the rear lights of a VAZ 2114 or 2109 do not work may be a completely typical problem: a breakdown of the switch (button) itself. If everything is fine with the button, you should check whether the wire is oxidized. Otherwise, the contact will need to be cleaned. 5. The size fuse is on. If the fuse is constantly burning, it is possible that there is a poor contact in the fuse box or a wire is shorted somewhere. In this case, you should check it: connect a 12 Volt light bulb to its contact (via + and -). If the lamp lights up, it means there is a short circuit somewhere. To find it, you will have to turn off all devices operating in conjunction with this fuse one by one. To do this, you will have to check the wires going to the license plate illumination on the trunk roof. Usually these contacts are frayed and shorted. Another weak point, which is why the dimensions of the VAZ 2114 or 2109 do not work, may be in the cable located at the driver’s left foot on the back side of the wing under the mat. By disconnecting this cable, the license plate and interior lamp lighting are also disconnected. If after disconnecting the loop the lamp on the fuse goes out, it means there is a short circuit in this loop. In this case, you will need to inspect the entire wiring circuit in this node.

What is especially important to control at the rear dimensions

If the control light on the key does not light up, but the dimensions work, then first look at the panel wiring. Remove the key block from the socket, then wipe the contacts with alcohol. If the dimensions on the right side do not work simultaneously with the warning lamp, then check the fuse. It is worth noting that they rarely fail, since the VAZ-2114 began to install wide options that have a reliable contact pad.

If F10 or F11 still breaks down frequently, then it is necessary to check the mounting block; it may be faulty. If this unit is in working order, then check the entire electrical circuit. Sometimes constant failure of fuses indicates a short circuit in the wiring, which can lead to a car fire for no apparent reason.

We repair damage to the front and rear side lights on a VAZ 2114

Any car, according to today's standards of traffic regulations, must be equipped with a certain set of lights of various colors and sizes. This includes brake lights, low beam and high beam headlights. But the dimensions of the VAZ 2114 are of most interest:

• Front right and left;
• Likewise the rear ones.

Tail lights

The engineers positioned them so that they could be seen from any side, that is, from each side of the car. Their purpose is to notify drivers about the presence of a car in a particular place with constantly burning yellow lights. In addition, side lights must be turned on along with low beam headlights when driving according to today's traffic rules. Accordingly, their absence entails the imposition of a fine, so it is necessary to monitor the condition of the dimensions regularly, and repair breakdowns in a timely manner. Let's figure out why the dimensions of the VAZ 2114 do not work and how this issue can be resolved in any case.

What are side lights?

Parking lights, also known as parking lights, are lights that are located on the sides, front, and rear of a vehicle.

The side lights must be turned on if you are driving in the dark, while braking and stopping, as well as while parking the car on the roadway or side of the road.

Front dimensions

The dimensions located on the front of the car are called sidelights and parking lamps. They are located on the same line along the edges on the front of the vehicle. Dimensions on trucks are located on the fenders. The front marker headlights must glow exclusively white.

According to the traffic rules of the Russian Federation, front lights are turned on at night in conditions of poor visibility together with other optical devices, such as fog lights, high beams and low beams.

Rear dimensions

Rear dimensions are installed in the corresponding part of the car on the sides along one line and are part of the headlights. Rear lights should only be red and turn on at night

when driving and stopping at the edge of the road. On trucks and buses, the dimensions are installed both in the upper and lower parts.

Drivers often confuse headlights with low and high beam running lights and fog lights, which should not be allowed. All running lights have their own purpose.

What are they needed for?

Side lights are of particular importance when driving a vehicle. Purpose of side lights:

• designation of vehicle dimensions when visibility on the road is insufficient;
• as lighting when stopping;
• attracting the attention of other road users.

Technical device

In some situations, it happens that the rear lights of a VAZ 2114 do not light up, in other cases only the front ones, but their structure and operating principle are identical. The side lights are located in the turn signal housing, while the front and rear lights find a place in the headlight housing in the same area. There is a special button for the side lights on the dashboard, which allows you to control them; next to it there are headlight switches and other lighting. When the driver touches this button and turns them on, at the same time the corresponding light on the dashboard lights up, which will not allow the driver to forget about the action taken.

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.

Malfunctions and their elimination (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.

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.

We recommend: Antifreeze or antifreeze, which is better to fill and what is the difference?

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.

Flashlight board VAZ 2108, VAZ 2109, VAZ 21099

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.

Parts prices

There is also a separate section for prices for all the parts that may be needed when repairing this part of the car, because if the side lights on a VAZ 2114 or the fuses have blown, they will still have to be replaced with new ones. In any case, all the components are quite cheap, all we might need:

• Marker lamp;
• Fuse;
• Power button;
• A whole fuse block.

Today, an ordinary white light bulb costs up to 30 rubles; of course, the price depends on the individual pricing policy of a particular seller. Individual fuses can be selected for up to 50 rubles, unless, of course, you want to install a higher quality option. Button, if you look for exactly the same one as the original one, you will have to pay up to 300 rubles. In some situations, more serious problems may arise and you will have to change the entire unit, this is quite an expensive proposition, together with all the wires it will cost up to 1000 rubles.
