Without Pulse

Whenever the Ignition Switch is in the "ON" or "START" position, Battery voltage is applied through the WIPER WASHER Fuse to the Front Wiper/Washer Switch (in the COMBINATION SWITCH) and FRONT WIPER MOTOR Pawl and Switch contacts.

Washer Operation
When the Front Wiper/Washer Switch is pulled back, Battery voltage is applied through the Wash Switch to the FRONT WASHER PUMP. The FRONT WASHER PUMP is permanently grounded at G104 and will operate as long as the Wash Switch is engaged. To initiate wiper operation, the Front Wiper/Washer Switch must be turned to the "LO" or "HI" wiper positions.

Low Operation
With the Front Wiper/Washer Switch in the "LO" position, Battery voltage is applied through the WIPER WASHER Fuse, and the "LO" contacts of the Front Wiper/Washer Switch to the LOW side of the FRONT WIPER MOTOR. Since the FRONT WIPER MOTOR is permanently grounded at G109, the motor operates at low speed as long as the switch remains in this position. When the switch is placed in the "OFF" position, the Pawl and Switch assembly provides voltage to the motor until the wipers are in the PARK position.

High Operation
With the Front Wiper/Washer Switch in the "HI" position, Battery voltage is applied through the WIPER WASHER Fuse, and the "HI" contacts of the Front Wiper Washer Switch to the HIGH side of the FRONT WIPER MOTOR. Since the FRONT WIPER MOTOR is permanently grounded at G109, the motor operates at high speed as long as the switch remains in this position. When the switch is moved to the "OFF" position, the Pawl and Switch assembly provides voltage to the motor until the wipers are in the PARK position.
