2. Disconnect the wire from the negative terminal of the battery (see "Battery - Removal and Installation").
Replacing the wiper relay (PC514)
The windshield wiper relay is located in the passenger compartment on the left side of the body under the instrument panel and is designed to provide intermittent operation.
To complete the job you will need two plastic trim holders.
1. After removing the seal from the flanging of the front pillar of the driver's door, use a screwdriver to pry up the side panel trim and remove it, removing the two holders from the holes in the side panel (the holders are usually destroyed in the process). We bend back the sound insulation.
2. Disconnect the relay wiring block from the harness. The connector is located at the bottom of the instrument panel.
3. Using a Phillips screwdriver, unscrew the two screws and remove the relay.
4. Installation of all removed parts is performed in the reverse order. We fix the side panel trim with new holders.
Replacing the turn signal and hazard warning light relay (231.3747 or 23.3747)
The flasher relay is installed on the engine compartment bulkhead behind the instrument panel. The relay is designed to receive an intermittent light signal from the turn signals both in the emergency signaling mode and in the turn signaling mode and to check the serviceability of the turn signal lamps. If the lamp burns out, the relay doubles the flashing frequency.
1. Remove the instrument panel (see "Instrument cluster - removal and installation").
2. With a socket wrench by 10 mm unscrew the relay mounting nut. Under the nut are the tips of two "ground" wires.
3. Disconnect the wiring harness from the relay.
4. Installation of all removed parts is carried out in reverse order.
Replacing the headlight relay (90.3747-10 or 113.3747-10)
Two relays for switching on the low and high beam are installed in the engine compartment on the upper part of the right mudguard.
1. Using a Phillips screwdriver, unscrew the mounting screw and remove the relay. Under the high beam relay mounting bracket is the tip of the ground "wire".
A - high beam relay, B - low beam relay.
2. Having marked or remembered the location of the wires, we disconnect them from the relay terminals. For convenience, you can sequentially disconnect the wires, immediately connecting them to a working relay.
3. Installation of all removed parts is performed in reverse order.
Replacing the Battery Charge Indicator Lamp Relay (PC702)
The relay is installed in the engine compartment on the upper part of the right mudguard. The relay is used to turn on the control lamp on the instrument panel when a malfunction occurs in the battery charging circuit. When the ignition is on, the control lamp lights up, and after the engine starts (with a functioning charging circuit) the lamp should go out.
1. Using a Phillips screwdriver, unscrew the two mounting screws and remove the relay. The "ground" wire is secured under one of the screws.
2. Having marked or remembered the location of the wires, we disconnect them from the relay terminals. For convenience, you can sequentially disconnect the wires, immediately connecting them to a working relay.
3. Installation of the relay is performed in the reverse order.
Replacing the cooling system radiator fan relay (90.3747-10 or 113.3747-10)
The radiator fan relay for the cooling system is installed in the engine compartment on the upper part of the left mudguard.
1. Using a Phillips screwdriver, unscrew the mounting screw and remove the relay.
2. Having marked or remembered the location of the wires, disconnect them from the relay terminals. For convenience, you can sequentially disconnect the wires and immediately connect them to a working relay.
3. Installation of the relay is performed in the reverse order.
