Pic. 150. Windshield and rear window washer jets:
1 - rear window washer jet; 2 - sprayers; 3 - seals; 4 - windshield washer jet.
The liquid from the tank is pumped through solenoid valves (when voltage is applied to them) through the tubes to the washer jets. Through the nozzles 2, inserted into the spherical sockets of the housings 4 of the jets, the liquid is supplied to the upper zone of the sectors described by the cleaner brushes. Regulation of the direction of the jet is carried out by changing the position of the nozzle in the jet socket. To do this, insert a needle into the jet sprayer hole and gently turn the sprayer so that the liquid jet hits the desired area.
In the warm season, clean water can be poured into the tank, and in the cold season (up to minus 25°С) only a mixture of 25... 33% liquid NIISS-4 (TU 38-1-02-30-76) or «Auto glass cleaner-2» (TU 6-15-1363-82) with water (30 cm3 for 1 liter of water).
The operation of the cleaners and washers is controlled by their switching lever. This lever is located on the right side of the steering column and has the corresponding symbols - position indicators. Each of the eight positions of the lever corresponds to a certain mode of operation of the cleaners and washers:
- I - wipers and washers of the windshield and rear windows are turned off;
- II - non-fixed position of the lever, the intermittent operation of the windshield wiper is on;
- III - fixed position of the lever, the intermittent operation of the windshield wiper is on;
