System Operation

SWITCH POWER SUPPLY
Whenever the ignition switch is in the "ON" or "START" position, battery voltage is applied through the WIP Fuse to the Front Wiper/Washer Switch and the FRONT WIPER MOTOR.

WASHER OPERATION
When the Front Wiper/Washer Lever is pulled, battery voltage is applied through the Front Wiper/Washer Switch to the FRONT WASHER PUMP. The FRONT WASHER PUMP is permanently grounded at G101 and will operate as long as the Front Wiper/Washer Switch is engaged. The windshield wipers operate in the "LO" position while the Front Wiper/Washer Switch is engaged.

LOW SPEED OPERATION
With the Front Wiper/Washer Switch in the "LO" position, battery voltage is applied through the WIP Fuse and the "LO" contacts of the Front Wiper/Washer Switch to the "LO" side of the FRONT WIPER MOTOR is permanently grounded at G106, the motor operates at low speed as long as the switch remains in this position.

HIGH SPEED OPERATION
With the Front Wiper/Washer Switch in the "HI" position, battery voltage is applied through the WIP Fuse and the "HI" contacts of the Front Wiper/Washer Switch to the "HI" side of the FRONT WIPER MOTOR. Since the FRONT WIPER MOTOR is permanently grounded at G106, the motor operates at high speed as long as the switch remains in this position.
