Test H: The Washer Pump is Inoperative

PINPOINT TEST H: THE WASHER PUMP IS INOPERATIVE

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 windshield 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).

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