Normal Operation
Under normal operation, the windshield washer pump motor is grounded through internal relays in the wiper motors using circuits 941 (BK/WH) and 946 (VT/LG). The steering column multifunction switch provides input to the windshield wiper motor through circuit 1300 (VT) to activate the washer. The windshield wiper motor activates the internal relay and then provides power through circuit 941 (BK/WH). When the rear window washer is activated, the internal relay in the rear window wiper motor provides power through circuit 946 (VT/LG).

Possible Causes
- Open in circuits 941 (BK/WH), 946 (VT/LG) and 1300 (VT)
- Inoperative steering column multifunction switch
- Inoperative windshield washer pump motor
- Inoperative windshield wiper motor
- Inoperative rear window wiper motor
