Test I: The Washer Pump is Inoperative

PINPOINT TEST I: THE WASHER PUMP IS INOPERATIVE

Normal Operation
Under normal operation, the washer pump motor is grounded through internal relays in the wiper motors using circuits CRW14 (BU/WH), GD120 (BK/GN) and GD133 (BK). The multi-function switch provides input to the windshield wiper motor through circuit CRW07 (GY/BN) to activate the windshield washer. The windshield wiper motor activates the internal relay and then provides power to the washer pump through circuit CRW14 (BU/WH). The multi-function switch provides input to the rear window wiper motor through circuit CRW20 (GY/YE) to activate the rear window washer. When the rear window washer is activated, the internal relay in the rear window wiper motor provides power through circuit GD120 (BK/GN).

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Multi-function switch
- Washer pump motor
- Windshield wiper motor
- Rear window wiper motor
