Fuses and relays

Relay

The location and purpose of relays and fuses, depending on the modification of the car, may differ. The designation of the controlled and protected electrical circuit is marked on the cover of the unit.

The main unit is located at the rear of the engine compartment on the driver's side. The additional block in cars manufactured before 01.1991 is located above the glove box, and in cars manufactured from 01.1991 in the rear part of the engine compartment on the passenger side.

Relays can switch high currents at a distance, thus allowing the use of weak control switches and wiring.

Unlike mechanical switches, relays can be controlled by more than one signal.

Some relays can be timed, such as intermittent wipers or heated windshields.

If a fault is detected in a circuit equipped with a relay, then it must always be remembered that the problem may lie precisely in the relay. Testing can be done by replacing with a known-good relay.

To replace the relay, remove it from the socket and insert a new one. The relays in the main box are accessed in the same way as the fuses. Access to the relays located under the instrument panel is carried out after removing its upper part.

The sunroof relay is located in the overhead console.

Circuit breakers

The battery is protected against short circuits by a fuse on the positive side.

The main fuse and relay box is located on the right in the engine compartment, near the bulkhead. It contains up to 24 fuses and almost the same number of relays (depending on equipment). The list of fuses is on the back of the unit cover.


There is an additional fuse box in the passenger compartment, which can be accessed after opening the glove box lid.

The fuse for the radio receiver is located on the radio power cable under the front panel on the left side near the heater.

All fuses are blade type and are color coded to match the fuse's specific protection current. The health of the fuse is determined by the presence of a wire conductor connecting the contacts of the fuse.

To replace a failed fuse, you must first turn off the corresponding electrical circuit. Remove the failed fuse from the socket using tweezers or special grips.

If the newly installed fuse instantly fails when voltage is applied, the protected electrical circuit should be checked. If the fuse protects several electrical circuits at the same time, they must be connected in turn in order to determine the faulty circuit by blowing the fuse and then eliminate the malfunction.

It is not recommended to install a high current fuse instead of a failed one, as this can lead to serious damage, including fire.

In some electrical circuits, such as electric window and seat adjustment motors, thermal relays are installed instead of fuses, which automatically turn on after the overload is removed.
