VAZ turn signal relay - do-it-yourself diagnostics and replacement


Turn signals are designed to inform other road users about an upcoming maneuver. If they malfunction, the likelihood of an accident during maneuvering increases greatly. The most common cause of such a breakdown is a non-functioning VAZ 2107 turn relay. Traffic regulations prohibit operating a car with faulty light signals, so if such a malfunction is detected, it must be eliminated as soon as possible. This work can be performed by service station specialists.

However, replacing the turn relay is a fairly simple and not very labor-intensive operation, available even in the field. Therefore, knowledge about the design and method of replacing the VAZ 2107 turn signal relay will not be superfluous for owners of the “Seven”.

Where is the turn signal relay located on the VAZ-2107

Direction indicators, which are used in the design of absolutely any car, regardless of their model and brand, are designed to indicate the maneuver being performed. They allow other road users to immediately know that you intend to turn and are quite capable of preventing a traffic accident. The operation of the indicators, as well as their blinking during maneuvers, is ensured by the turn relay. In the 2107, it is an electronic device designed using semiconductors. In addition to them, the design of the device uses an electromagnet, which opens and connects contacts according to a certain pattern.

Location of the turn relay in VAZ-2107 cars

In order to easily and quickly fix any malfunctions of the VAZ-2107 turn relay, it is important to know where this device is located. Its location depends on the modification of a given car model:

  • in cars with injection engines, the relay is located in the engine compartment, in a specially designed mounting block;
  • in carburetor "sevens" the turn relay can be located directly in the cabin, behind the dashboard. In this case, to gain access to it, you will need to dismantle the torpedo, which will take much more time.

If the turn relay is located behind the dashboard, you can try to very carefully pry it up with a screwdriver and pull it towards you as far as possible.

Sometimes the length of the wires is quite enough to remove the part and install a new one.

FEATURES OF REPLACING THE BREAKER

For the “Seven” with a carburetor engine, there are some special features when changing the breaker.

In a VAZ 2107 with a carburetor engine, the difficulty of replacing the turn signal relay lies in the fact that it is located in the car interior behind the dashboard. To replace, the panel must be removed. This involves some inconvenience, but it can be done in your own garage.

Before you begin work on replacing the turn signal relay, you must remove the negative terminal from the car battery or disconnect the ground, if any.

The work is performed as follows:

  1. On the panel, to the right of the instrument panel, remove the daily mileage reset button.
  2. Remove the handles from the manual climate control levers in the cabin.
  3. On the right side of the panel, remove the plug covering the screw that secures the panel. Unscrew the screw.
  4. Disconnect the panel latches from the frame using a screwdriver. Pull the panel and remove it from the niche.
  5. Disconnect the wires leading to the panel.
  6. Unscrew the speedometer cable.
  7. Remove the econometric pipe, if equipped.
  8. Move the instrument panel to the side.
  9. Visually determine the placement of the relay. It is located to the right of the steering column.
  10. Disconnect the relay from the wires by pulling out the terminal block.
  11. Unscrew the nut securing the device.
  12. Remove the breaker.
  13. We connect the terminals with wires to the new relay and screw it on.

Further assembly and installation is carried out in the reverse order. After finishing, connect the battery and perform a test.

Having familiarized yourself with the theory of replacing the turn relay on a VAZ 2107, each owner of a “Seven” can independently solve this simple, important problem.

Symptoms of a faulty turn relay

Turn signals, as well as the relay that ensures their correct operation, make it possible to minimize the risks of

road traffic accidents when performing any maneuvers. That is why it is necessary to constantly maintain them in good condition and promptly eliminate any malfunctions.

The failure of the turn relay may be indicated by the following symptoms, which can actually be identified even without experience and diagnostic work:

  • The turn signals do not blink, but stay on continuously. This indicates a breakdown of the electromagnet, which is stuck in one of two positions. Most likely, the relay may need to be replaced;
  • The turn signal lamps flicker too quickly or, on the contrary, too slowly. This problem may be caused by incorrectly selected power of the light sources, however, it does not hurt to check the functionality of the relay;
  • The turn signals don't work at all. It is quite possible that the cause of the breakdown is a burnt-out light bulb, a broken electrical contact, or a failed fuse. But if all these parts work normally, the problem lies in the turn relay.

Finding out that the device is not working is not difficult at all. If you do not hear characteristic clicks when you turn on the turn signals, then most likely the relay has failed and requires urgent replacement.

What to do if the battery is boiling

The lamp goes out, the voltmeter needle goes to the right into the red sector, and there is a sharp “chemical” smell in the cabin. At idle, the needle is in the green sector, but as soon as you accelerate, it goes all the way to the right. This indicates that the voltage regulator (chocolate) has failed. If this happens, moving on is more expensive! All the electrical equipment of the car may burn out, and the battery will get damaged, the electrolyte will “boil”, the plates may become warped. To get to the repair site, you can temporarily turn off the generator by removing the wire from terminal “61” of the generator. You can drive for quite a long time on a good battery, just don’t forget to turn off unnecessary electrical appliances - heater fan, heated rear window, radio, etc. Headlights or running lights will have to be left.

Voltage too high (overcharge)

This article describes a simple way to determine if the alternator, voltage regulator, or connections between them are faulty. How to repair all this in the next article.

VAZ2105 stopped working, the right rear turn signal in front works. When you turn it on, the engine starts to heat up and the fuses light up. Tried the emergency lights, same situation. the left one works. what to do

Hello, my 2106 has lost turns, I turn on the emergency lights, they light up but don’t blink, tell me what could be wrong

Hello, please tell me I can’t find the reason. on the panel there is no sign of a light turning. But when you turn it on, it works and the emergency lights also work. The relay clicks and the light does not shine on the panel. How to find out the reason, thanks in advance.

Thank you)) helped me get home on a jig))

Hello Vyacheslav, I have a Niva 2121, produced in 1980, with an 8-pin emergency button. I want to install a 6-pin one, like you have on your car, how do I connect it correctly? Waiting for your answer please!

When my emergency lights are turned on, the instruments and turn signals do not work

You are simply a Super Master from God. You explain everything very clearly and clearly about this common problem. Tell me, have you tried to repair the steering column switch, is it repairable?

I have a VAZ 2107. The hazard warning lights and the left turn signal work, but the right one does not. What is the reason?

Good day. That's the problem. The turn signal lamp shines at a lower frequency in the high beam when the ignition is on. If you drive for a long time on the far one, the signal disappears, unless you switch to the near one and back. As soon as I turn the dimensions, the turn control blinks once. Help

thanks saved me time.

and here I am, the father of the girl who wrote to you about my problem with the turn signals on the VAZ 2103: the turns themselves work, but when I turn on the side lights or headlights, the turns light up constantly. What do you recommend doing in this situation?

Hello, my dad has a VAZ 2103 and the car has this problem: the turn signals work, but when you turn on the side lights or headlights, the turn signals glow with a constant light, which is not normal. Please tell me what needs to be done, otherwise our auto electricians don’t want to delve into old Lada cars. Thank you in advance.

Please tell me about this problem. VAZ-2107, when turning on the right turn or emergency lights, the turn relay heats up and the turn relay lights up, before that the fuse burned out. Left turn works fine. It's short somewhere, but I can't figure out where.

There is a fuse in the circuit there.

To help prevent all turns from turning and crashing, only the light bulb in the device does not shine, so you can tell it to work.

How to remove the turn signal relay

As we mentioned above, on cars with a carburetor engine, disassembling the dashboard may be required to remove the turn relay.
This is a rather lengthy procedure that requires appropriate experience. On modifications of the VAZ-2107 with more modern injection engines, removing the turn signal relay is much easier:

  • open the hood and get to the mounting block;
  • we find the relay;
  • we pry up the device and pull it upward;
  • disconnect the wires connecting the relay to the vehicle's on-board network.

After this, you can quickly install the new part and securely fix it in the mounting block.

Turning relay for VAZ-2107

Every car has turn signals, the main purpose of which is to inform other road users that a maneuver is being performed or intended to be performed. If your car's turn signals are not working, it greatly increases the likelihood of an accident when maneuvering or changing lanes. Why don't turns work on the VAZ 2107? The causes of such a breakdown in frequent cases are nothing more than the turn relay. Today we will pay attention to the question of how to replace this relay on the “seven”.

Communities › [email protected] › Blog › Turn signals disappeared, hazard lights remain (VAZ classic)

This is the situation guys. The hazard lights function, but the turn signals do not.

I’ll announce the speclist right away. The steering column switches are working - I checked them, rang them, everything closes as it should.

The turn relay is electronic and new. The wiring is new, both in the cabin and under the hood. The fuse box is also new, no fuses have blown. The ignition relay, which is responsible for the voltage in the turn signal circuit, is activated and supplies 12V at the moment the ignition is turned. The ignition switch contact group is also new.

I ask for help, classicists brothers!

Location in the car

There are two types of location of turn signals in the classic VAZ family of cars, depending on the modification:


Let's start disassembling

  1. Early modification models

To get to the relay, you need to remove the plug by unscrewing the bolt on the dashboard.

We pull the entire panel towards us, move the sensor panel a little to the side so that we can get to the relay.

  • The contacts approach the relay from below.
  • Disconnect the contacts.
  • We remove the old device and install the new one.
  • We put the dashboard back, sliding it into the side grooves.
  • Screw in the bolt.

We check the turn signals for flickering and characteristic clicks. The frequency of contact closure should be approximately 1 time per second.

The technology is very simple. The main difficulty here is accessibility to the relay. The space under the panel of these models is small, getting there is problematic.

  1. Later models
  • Remove the screws from the steering column switch housing. We remove the casing elements.

  • Unscrew the mounting bolt.
  • We take out the devices on the electrical wiring inside the cabin.
  • We replace the old relay with a new one.
  • Screw it back. We put the covers in place.

Important: it is recommended to replace the relay itself or the mounting block as an assembly, given that the wiring often burns out and restoring the contacts is quite problematic.

When replacing any of the above relays, special attention should be paid to contact insulation. Insulation is performed using hollow mass braiding. To tie the wires, use a special strip clamp.

Change the turn signal relay, the Avriyka chain and the turn signal chain are different circuits. As far as I remember, in the VAZ - 2101 and VAZ - 21011 (classic version without modifications) there are NO emergency lights AT ALL. Apparently you have a hybrid. We remove the dashboard and look there carefully. There may be a black box a la VAZ - 2106, 2105, or a terrible, terrible one from a VAZ - 2107. You can try it out, usually the wire from the contactor in the relay breaks, but I don’t recommend it, take a 10mm socket wrench, unscrew it (or a screwdriver, if the collective farm is not a factory) we take it to the store, buy a new one, install it and move on)))) And we don’t think about the fact that if we recently installed it, then it can’t break. Believe me, it breaks!

Well, let's start with the fact that I have a 2105. The turn relay is not a thermal one of the USSR, but an electronic one on a microcircuit. If properly sealed, it never dies. The voltage on the orange wire, which is responsible for the turn signals, has disappeared. For now, I temporarily eliminated it simply by running a wire from the ignition switch, so that at least I could move around with the turn signals. I’ll continue to think about where the treasured 12V went from fuse F10 in the new mounting block with flag fuses.

I wouldn’t chop it so hotly that it never dies. From my experience I can say that if the wire is checked on both sides and it turns out to be intact, then the problem is in the contacts to which it is connected. And don’t be offended about the relay, I have used all rear-wheel drive and all-wheel drive VAZs, I can say with confidence NEVER say NEVER. In those recent times, they simply shared their experience in garages and such cases happened, you can’t put it on your head. And so, I think it’s worth checking the connection of the wire in the chip itself and the integrity of its connection on the fuse box, and also check the presence of power at the fuses

check if the power to the turn signal is going to the fuse block when it is turned on; if not, ring the steering column switch. In general, look by the method of elimination. From the consumer (light bulb) there is a fuse, etc.

I’ll go with the tester to connect the wiring... I’ve just been worried for 2 months now... I’ve tried all the options. I checked the coincidence of the chips (they got mixed up a little) everything is in order... And the emergency lights are working... There are no turn signals...

The emergency light is not connected to the turn signal; usually it goes directly from the battery.

what about the turn signal switch? click it and see if there is a plus or not.

Transition from an electromagnetic-thermal relay to an electronic one.


This “barrel” is located under the dashboard of a car. This is an electromagnetic thermal relay. Due to short-term operation (1-2 months), it is recommended to replace it with an electronic one. After this time, it begins to burn or shorts out.

The following are the steps to replace it:

  • disconnect the contact terminals;
  • We mark each wire with a marker, or use paint to highlight it in different colors;
  • contact No. 1 of the electronic relay is connected to the wire with the x sign;
  • Contact No. 2 of the electronic relay is connected to the wire marked L;
  • contact No. 3 of the electronic relay is connected to the wire marked P;
  • Contact No. 4 is ground, we connect it to a separate wire.

All this work must be carried out when using heat shrink.

The replacement of incandescent lamps with LEDs in direction indicators is gaining great popularity due to the fact that incandescent lamps are much inferior to LED lamps in terms of service life and light output.

Turn relay VAZ 2107

Turn signals are designed to inform other road users about an upcoming maneuver. If they malfunction, the likelihood of an accident during maneuvering increases greatly. The most common cause of such a breakdown is a non-functioning VAZ 2107 turn relay. Traffic regulations prohibit operating a car with faulty light signals, so if such a malfunction is detected, it must be eliminated as soon as possible. This work can be performed by service station specialists.

However, replacing the turn relay is a fairly simple and not very labor-intensive operation, available even in the field. Therefore, knowledge about the design and method of replacing the VAZ 2107 turn signal relay will not be superfluous for owners of the “Seven”.

Malfunctions of turn signals VAZ 2107

The main symptom of a malfunction is non-functioning direction indicators. However, the reason may not be only the relay. There are several possible breakdowns:

  • The turn signal lamps are constantly on and do not blink. This indicates a malfunction of the electromagnetic part of the VAZ 2107 turn signal relay - the contacts are stuck in the closed position and do not open. This could be either a burnt-out contact of the electromagnetic relay or a failure of the electronic circuit of the turn relay. Regardless of the specific reason, there is only one way out - replacing the VAZ 2107 turn signal relay.
  • Lights flash too slowly or quickly. The reason may be either in the electronic part of the turn relay or in the discrepancy between the current consumption of the lamps and the nominal one. If one of the lamps has burned out or lamps that consume less current are installed, the turns will flash more often than necessary. The same phenomenon occurs if the wire going to one of the lamps is broken, or the lamp socket or base is oxidized. A similar phenomenon occurs when installing LED lamps instead of incandescent lamps. When installing more powerful lamps, the blinking frequency decreases. If all the lamps are in working order and the malfunction did not appear after replacing the lamps, the reason lies precisely in the turn relay or poor contacts in the lamp power circuit.
  • The direction indicator lamps do not light up. The cause of the malfunction may be a broken turn switch, a burnt-out (faulty) turn relay, an open circuit, or a blown fuse. It is better to start checking from the last one

Purpose of the device

Initially, it should be noted that turns operate differently than other lights on a car. They operate in intermittent mode, which is ensured by a product such as the VAZ-2107 turn relay (breaker).

It should also be noted that in addition to intermittent operation, the turn relays emit audible signals in the form of clicks, which help the driver. By these clicks, the driver understands that the device is currently functioning.

In addition to the fact that the breaker is responsible for the functioning of the light alarm necessary for maneuvers, it also allows them to work in emergency mode. The VAZ-2107 uses an electronic relay, the blinking frequency of which lamps depends on the settings of the electronic circuit. Above is a photo of a modern electronic turn signal relay, which is used on VAZ-2107 cars.

Diagnosis of turn signal faults

If one day the turn signals stop functioning, this indicates that it is time to diagnose the car. To do this, there is no need to go to a service station, but you can do everything at home. The following signs indicate that the mechanism has stopped functioning:

  • When turned on, the turn signals light up, but they do not flicker. This type of failure is directly related to the failure of the relay. To correct the problem, you need to replace the breaker.
  • Accelerated or slow flickering of turn signals. Accelerated flickering indicates that the filament of one of the lamps has burned out. Slow flickering indicates that at least one lamp of higher power than recommended is connected to the circuit. With the advent of modern LED lamps, many motorists are eager to install them on their cars. When installing LED lamps in turn signals, they flicker too quickly, this is due to their low power consumption.
  • The devices do not function at all. The reason may be a malfunction of the relay, fuse, steering column switch or hazard warning light button. The connection diagram is designed so that the power for the turn signals passes through the emergency light button. If the button is faulty, then the turns will not function.
