Replacing the turn relay VAZ 2114
Now it’s time to talk about how to change the turn relay on a VAZ 2114. To carry out all the work you will need: - patience and free hands.
Replacement instructions:
- The first stage is the simplest - open the hood of the car.
- At the second stage, you need to find the mounting block in which the desired product and fuses are located. Let us remember that the location of the MB is located directly above the right (driver's shock absorber strut).
- To access the contents of the block, we will need to open its plastic protective cover. This can be done by unlatching the two side latches.
- Now you can observe the entire internal structure of the box, however, we are only interested in the product marked K2. Keep in mind that pulling the part out by hand is quite problematic and inconvenient. Especially for such purposes, you can find specialized plastic tweezers in the block, with the help of which it is very convenient to pull out the part and fuses, which we will certainly use.
- To reinstall, take a new product and insert it into the seat so that the three metal contacts are inserted into the socket. After this, press the body of the device and fix it firmly. This completes the replacement of the VAZ 2114 turn signal relay.

Replacing the turn signal relay for a VAZ 2107
The design of the relay does not provide for the possibility of its repair. If a malfunction is detected, the part must be replaced.
If the relay is located in the mounting block, to replace it, simply follow these simple steps:
- open the cover of the mounting block;
- pry with a screwdriver and remove the old relay;
- install a new relay;
- close the cover of the mounting block.
If the relay is located behind the dash, it is much more difficult to replace. To avoid a short circuit, it is better to disconnect the ground wire from the battery. Replacing the turn signal relay is done as follows:
- Unscrew and remove the button (handle) of the daily mileage counter.
- Remove the decorative handles from the interior heater control levers.
- Remove the decorative plug from the dashboard mounting screw.
- Unscrew the screw.
- Unclip the dashboard fasteners by prying it up with a screwdriver.
- Unclip the wire connectors from the instrument panel.
- Unscrew the speedometer cable by hand.
- Remove the dashboard.
- Unplug the wire terminals from the relay by turning.
- Unscrew the relay mounting nut.
- Connect wire terminals
- Reinstall the relay and tighten the mounting nut.
- Connect the wire terminals to the dashboard.
- Screw the speedometer cable to the dashboard.
- Place the panel in place by snapping the fasteners into place.
- Tighten the screw that secures the dashboard.
- Install decorative handles on the heater control levers.
- Screw on the trip odometer handle.
- Install the decorative plug onto the self-tapping screw.
After this, you need to connect the ground wire to the battery. Replacing the turn signal relay is now complete.
Turn signals are perhaps a very important part of any vehicle. Carrying out maneuvers on the road becomes a rather dangerous task if. The VAZ 2107 turn signal and hazard warning relay is responsible for the correct operation of the direction indicators. This device is used on all cars of the classic family. Let's consider why a turn signal relay is needed, how is a relay malfunction determined and how is it replaced?

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
VAZ2107 fuse and relay diagram
The electrical wiring of the machine is protected by fuses, which are mainly installed in the central and additional units, located at the bottom of the instrument panel on the left side next to the steering column. The circuit from the battery to the terminals and connections is closed when the car ignition is turned on.

Owners of 2106 should be aware that the old design of fuses has long become obsolete, since each time they operate they overheat, which affects the density of the cells. Lack of tight contact between the fuse and the connectors leads to their burning. Therefore, replacement of the fuse blocks is necessary. To avoid unnecessary problems with the electrical wiring, you should inspect the safety devices every six months. If the contact part burns, it is necessary to replace the fuses and clean the sockets. Today, many VAZ 2106 owners are modernizing classic blocks, replacing them with modern blade fuses.
Turn relay VAZ 2107
Unlike other lighting devices, the direction indicators operate intermittently and flash. A special device is responsible for the operation of the indicators - the VAZ 2107 turn signal relay. In addition to ensuring the blinking of the lamps, the relay performs a signaling function. It notifies you of the operation of the turn signals with audible signals - clicks.
At first, a thermal relay was installed on VAZ cars, in which the contacts were closed (opened) by a nichrome string, which heated and cooled due to the current passing through it. In later models, which include the “seven,” a relay with an electronic circuit and an electromagnet is used. The blinking frequency of the direction indicator lamps is determined by the settings of the electronic circuit. This design has fewer moving parts and contacts, and is therefore more reliable.
The device also performs the function of a VAZ 2107 emergency flasher relay, causing the lamps to flash when the hazard lights are turned on.

Diagnostics of malfunction of the direction indicator relay VAZ 2107
If one day the turn signals stopped working. It's time to check what happened and, if possible, replace the faulty part of the circuit. Malfunctions of the turn signal relay can be recognized by several signs:
- The turn signals light up but do not flicker
. This directly indicates a breakdown of the relay, or rather, its electromagnetic part. In this case, the electromagnet has closed in one of the positions and cannot return to its original state. - The turn signals blink too quickly or too slowly
. This can happen, but not only due to the fault of the turn signal relay. Sometimes the flickering speed of lamps can change if the turn signals use lamps that are not of the same power as those specified by the manufacturer. However, it wouldn't hurt to install a new relay as a test. - The turn signals don't work at all
. This means that the turn signal lamps and the lamp on the dashboard do not blink and there are no corresponding relay clicks. However, as in the second case, the malfunction does not always concern the turn signal relay. Sometimes the reason is a faulty hazard warning button.
