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 CRW24 (GY) and CRW23 (VT/GN). 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 CRW24 (GY). When the rear window washer is activated, the internal relay in the rear window wiper motor provides power through circuit CRW23 (VT/GN).

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
