Some vehicles may be equipped with headlight and rear window wipers together with electromagnetic valves for headlight and rear window washing. The wiper connection diagram is shown in Figure 151. An auxiliary relay 7 (112.3747) is installed in the mounting block to switch on the headlight wipers. Its characteristics are the same as those of relay type 113.3747, described in the section "Lighting and light signaling".

Headlight cleaner
Consists of two (left and right execution) gear motors with levers and brushes. Thermal bimetallic fuses are installed in the gear motors to protect against overloads. Headlight cleaner gear motors are manufactured in a non-disassemblable design. Therefore, they cannot be repaired and, in the event of failure, must be replaced with new ones.
The headlight cleaner's number of double strokes of the gear motor shaft under a load torque of 0.05 kgf·m, a supply voltage of 12 V and an ambient temperature of (25±10)°C should be 45-60 per minute, and the consumed current should not exceed 1.5 A.
Rear window cleaner
Consists of a gear motor, a lever and a brush. The gear motor has a thermal bimetallic fuse to protect against overloads. The design of the gear motor allows it to be disassembled to eliminate minor faults (collector cleaning, etc.). The disassembly and assembly methods are similar to those described above for the windshield wiper gear motor.
For the rear window wiper, with a gear motor load of 0.05 kgf·m, a supply voltage of 14 V and an ambient temperature of (25±10)°C, the number of double strokes of the gear motor shaft should be (50±5) per minute, and the current consumption should not exceed 2 A.
