Pic. 129. Scheme of inclusion of cleaners and washer headlights and rear window:
1 - headlight cleaners; 2 - solenoid valve for turning on the headlight washer; washer motor; 4 - solenoid valve for turning on the rear window washer; 5 - mounting block; 6 - rear window washer time relay; 7 - relay for switching on headlight cleaners; 8 - ignition switch; 9 - switch of cleaners and washers of glasses; 10 - outdoor lighting switch; - rear window cleaner.
Headlight cleaner
The headlight cleaner consists of two (left and right execution) gearmotors with levers and brushes. The levers and brushes are placed in the lower position until the brushes stop in the block headlight limiters. Thermal bimetallic fuses are installed in the gearmotors to protect against overloads. Motorized headlight cleaners are available in a non-separable design. Therefore, they cannot be repaired and, in case of failure, must be replaced with new ones.
Headlight cleaners and headlight washer (electric motor 3 pumps and valve 2) switched on by switch 9 (lever position VII), if voltage is applied to the headlights by the outdoor lighting switch 10. An auxiliary relay 7 is installed in the mounting block to turn on the headlight cleaners.
Rear window cleaner
The rear window cleaner consists of a gearmotor, a lever and a brush. Laying the lever with a brush right in the direction of the car. The motor-reducers are equipped with a thermal bimetal fuse for protection against overloads. The design of the geared motor allows it to be disassembled to eliminate minor malfunctions (collector cleaning, etc.).
The rear window wiper is activated by switch 9 (lever position VIII). In lever position IX, relay 6 is switched on and the voltage from it is supplied to the washer pump motor 3 and to the valve 4 for supplying washer fluid to the rear window. The valve is activated and the liquid from the pump is supplied to the rear window. After the lever is returned to position VIII, the electronic relay 6 keeps valve 4 and washer pump 3 on for another 5 s.
The troubleshooting procedure for the headlight and rear window wipers is the same as described above for the windshield wiper.
