Rear

Washer Operation
Whenever the IGNITION SWITCH is in the "ON" or "START" position, Battery voltage is applied through the WIPER WASHER Fuse to the REAR WIPER/WASHER SWITCH. When the Rear Washer Switch is pressed, battery voltage is applied through the closed contacts of the switch to the REAR WASHER PUMP and to the REAR WIPER MOTOR. Because the REAR WASHER PUMP is permanently grounded at G104, the pump continues to operate as long as the Rear Washer Switch is held.

Rear Wiper Operation
Whenever the IGNITION SWITCH is in the "ON" or START" positions, battery voltage is applied through the WIPER WASHER Fuse to the REAR WIPER/WASHER SWITCH. When the Rear Wiper Switch is pressed, battery voltage is applied through the closed contacts of the switch to the REAR WIPER MOTOR. Since the REAR WIPER MOTOR is permanently grounded at G401, the motor operates as long as the REAR WIPER/WASHER SWITCH is ON. The REAR WIPER MOTOR also incorporates a Pawl and Switch assembly which allows the motor to receive battery voltage and complete the wipe cycle in the event that the REAR WIPER/WASHER SWITCH is turned OFF when the wiper is not in the PARK (down) position.
