Wiper Motor: Description and Operation

When the Ignition SW turned ON, current flows to TERMINAL 17 of the Front 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 through TERMINAL 17 of the Front Wiper and Washer SW --> TERMINAL 7 --> TERMINAL 3 of the Front Wiper Motor --> TERMINAL 1 --> GROUND, and causes the Wiper Motor to rotate at low speed.

2. HIGH SPEED POSITION
With the Wiper SW turned to HIGH position, the current flows from TERMINAL 17 of the Wiper and Washer SW --> TERMINAL 8 --> TERMINAL 2 of the Front Wiper Motor --> TERMINAL 1 --> GROUND, and causes the Wiper Motor to rotate at high speed.

3. INT POSITION
With Wiper SW turned to INT position, the Relay operates and the current which is connected by the relay function flows through TERMINAL 17 of the Front Wiper and Washer SW --> TERMINAL 2 --> GROUND. This flow of current operates the intermittent circuit, and current flows through TERMINAL 17 of the Front Wiper and Washer SW --> TERMINAL 7 --> TERMINAL 3 of the Front Wiper Motor --> TERMINAL 1 --> GROUND and the Wiper functions.
The Intermittent operation is controlled by a condenser's charged and discharged function installed in the relay, and the intermittent time is controlled by a time control SW to change the charging time of the condenser.

4. WASHER CONTINUOUS OPERATION
With Washer SW turned to ON, current flows TERMINAL 2 of the Washer Motor --> TERMINAL 1 --> TERMINAL 11 of the Wiper and Washer SW --> TERMINAL 2 --> GROUND, and causes the Washer Motor to run and the Window Washer to jet. This causes the current to flow to Washer continuous operation circuit in TERMINAL 17 of the Front Wiper and Washer SW --> TERMINAL 7 --> TERMINAL 3 of the Front Wiper Motor --> TERMINAL 1 --> GROUND, and the Wiper functions.
