Normal Operation

WARNING: This page is about a different car, the 2005 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.

During normal operation, the washer pump motor is powered through an internal relay in the wiper motor using circuit 941 (BK/WH). The multifunction switch provides input to the windshield wiper motor through circuit 684 (PK/YE) to activate the washer. The windshield wiper motor activates the internal relay and then provides power through circuit 941 (BK/WH).
