Relay
The location and purpose of the relays and fuses may differ depending on the vehicle modification. The designation of the controlled and protected electrical circuit is applied to the block cover.
The main unit is located in the rear of the engine compartment on the driver's side. The additional unit in cars manufactured before 01.1991 is located above the glove compartment, and in cars manufactured from 01.1991 onwards, in the rear of the engine compartment on the passenger side.
Relays can switch high currents over 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 operate on a timer, for example, in the intermittent mode of windshield wipers or windshield heating.
If a fault is detected in a circuit equipped with a relay, it is always necessary to remember that the problem may lie in the relay itself. The test can be carried out by replacing it with a known good relay.
To replace a relay, remove it from its socket and insert a new one. Access to the relay in the main box is the same as to the fuses. Access to the relays located under the instrument panel is carried out after removing its upper part.
The sunroof drive relay is located in the overhead console.
Fuses
The battery is protected against short circuit by a fuse on the positive side.
The main fuse and relay box is located on the right side of the engine compartment, near the bulkhead. It contains up to 24 fuses and almost as many relays (depending on the equipment). The list of fuses is on the back of the box cover.
There is an additional fuse box in the car's interior, which can be accessed by opening the glove compartment lid.
The fuse for the radio is located on the radio power wire under the front panel on the left side near the heater.
All fuses are blade type and have a color corresponding to a certain fuse protection current. The serviceability of the fuse is determined by the presence of a wire conductor connecting the fuse contacts.
To replace a defective fuse, first turn off the corresponding electrical circuit. Remove the defective fuse from the socket using tweezers or special grips.
If a newly installed fuse immediately fails when voltage is applied, the protected electrical circuit should be checked. If the fuse protects several electrical circuits at the same time, they should be connected in turn in order to determine the faulty circuit by the fuse blowing and then eliminate the fault.
It is not recommended to replace a faulty fuse with a higher current, as this may cause serious damage, including fire.
Some electrical circuits, such as the electric window and seat positioner motors, have thermal relays installed instead of fuses that automatically turn on after the overload has been eliminated.

Location of additional relays
The glow plug preheating relay for a diesel engine is located in the front right part of the engine compartment.
The relays for the anti-theft alarm, anti-lock brake system and automatic transmission downshift are located under the center of the instrument panel.
The window lift relay is located in the driver's door.
The rear wiper mode relay (Turnier) is located near the steering column.
