Wiper and Washer Systems: Description and Operation

With the ignition SW turned ON, the current flows to TERMINAL 17 of the front wiper and washer SW, TERMINAL 2 of the washer motor and TERMINAL 6 of the front wiper motor through the WIP fuse.

1. LOW SPEED POSITION
With the wiper SW turned to LOW position, the current flows through TERMINAL 17 of the front wiper and washer SW to TERMINAL 7 to TERMINAL 3 of the front wiper motor to TERMINAL 1 to GROUND and causes the wiper motor to run at low speed.

2. HIGH SPEED POSITION
With the wiper SW turned to HIGH position, the current flows through TERMINAL 17 of the front wiper and washer SW to TERMINAL 8 to TERMINAL 2 of the front wiper motor TERMINAL 1 to GROUND and causes the wiper motor to run at high speed.

3. INT POSITION (w/ INTERMITTENT OPERATION)
With the wiper SW turned to INT position, the relay operates and the current which is connected by relay function flows through TERMINAL 17 of the front wiper and washer SW to TERMINAL 2 to GROUND. This flow of current operates the intermittent circuit and the current flows through TERMINAL 17 of the front wiper and washer SW to TERMINAL 7 to TERMINAL 3 of the front wiper motor to TERMINAL 1 to GROUND and the wiper functions.
The intermittent operation is controlled by a charge/discharge function installed in the relay, and the intermittent time is controlled by a time control SW (W/ intermittent volume SW) to charge the charging time of condenser.

4. MIST POSITION (w/ MIST SW)
With wiper SW turned to MIST position, the current flows from TERMINAL 17 of the front wiper and washer SW to TERMINAL 7 to TERMINAL 3 of the front wiper motor to TERMINAL 1 to GROUND and causes to the front wiper motor to run at low speed.

5. WASHER CONTINUOUS OPERATION
With the washer SW turned to ON, the current flows through TERMINAL 2 of the washer motor to TERMINAL 1 to TERMINAL 11 of the front wiper and washer SW to TERMINAL 2 to GROUND and causes the washer motor to run and the window washer jet operates. This causes the current to flow to washer continuous operation circuit in TERMINAL 17 of the front wiper and washer SW to TERMINAL 7 to TERMINAL 3 of the front wiper motor to TERMINAL 1 to GROUND and the washer operate continuously.

6. WASHER OPERATION (w/o WASHER CONTINUOUS CONTROL)
With the washer SW turned to ON, the current flows from TERMINAL 2 of the washer motor to TERMINAL 1 to TERMINAL 11 of the front wiper and washer SW to TERMINAL 2 to GROUND and causes the washer motor to run and the window washer jet operates only while the washer SW is pressed.
