Normal Operation
Under normal operation, the windshield washer pump motor is grounded through internal relays in the wiper motors using circuits CRW14 (BU/WH) and CRW12 (GY/OG). The multi-function switch provides input to the windshield wiper motor through circuit CRW07 (GY/BN) to activate the washer. The windshield wiper motor activates the internal relay and then provides power through circuit CRW14 (BU/WH). When the rear window washer is activated, the internal relay in the rear window wiper motor provides power through circuit CRW12 (GY/OG).

Possible Causes
- Open in circuits CRW14 (BU/WH), CRW12 (GY/OG), CRW20 (GY/YE), CRW07 (GY/BN) or GD150 (BK/WH)
- Short to ground in circuit CRW14 (BU/WH), CRW12 (GY/OG), CRW07 (GY/BN) or CRW20 (GY/YE)
- Inoperative multi-function switch
- Inoperative windshield washer pump motor
- Inoperative windshield wiper motor
- Inoperative rear window wiper motor
