Wiper and Washer Systems: Description and Operation

With the Ignition SW turned ON, the current flows to TERMINAL A-9 of the wiper and washer SW, TERMINAL 2 of the washer motor and TERMINAL 6 of the wiper motor through the wiper fuse.

1. LOW SPEED POSITION
With wiper SW turned to LOW position, the current flows from TERMINAL A-9 of the wiper and washer SW --> TERMINAL B-8 --> TERMINAL 3 of the wiper motor --> TERMINAL 1 to GROUND and causes to the wiper motor to run at low speed.

2. HIGH SPEED POSITION
With wiper SW turned to high position, the current flows from TERMINAL A-9 of the wiper and washer SW --> TERMINAL A-8 -->TERMINAL 2 of the wiper motor --> TERMINAL 1 to GROUND and causes to the wiper motor to run at high speed.

3. INT POSITION
With wiper SW turned to INT position, the relay operates and the current which is connected by relay function flows from TERMINAL A-9 of the wiper and washer SW --> TERMINAL A-6 to GROUND. This flow of current operates the intermittent circuit and the current flows from TERMINAL A-9 of the wiper and washer SW --> TERMINAL B-8 --> TERMINAL 3 of the wiper motor --> TERMINAL 1 to GROUND and functions.

The intermittent operation is controlled by a condenser's charged and discharged function installed in relay and the intermittent time is controlled by a INT time control volume SW to charge the charging time of the condenser.

4. MIST POSITION
With wiper SW turned to MIST position, the current flows from TERMINAL A-9 of the wiper and washer SW -->TERMINAL B-8 -->TERMINAL 3 of the wiper motor --> TERMINAL 1 to GROUND and causes to the wiper motor to run at low speed.

5. WASHER CONTINUOUS OPERATION
With washer SW turned to ON, the current flows from TERMINAL 2 of the washer motor --> TERMINAL 1 --> TERMINAL A-13 of the wiper and washer SW --> TERMINAL A-6 to GROUND and causes to the washer motor to run. And window washer is jet.

This causes the current to flow washer continuous operation circuit in TERMINAL A-9 of the wiper and washer SW --> TERMINAL B-8 -->TERMINAL 3 of the wiper motor --> TERMINAL 1 to GROUND and function.
