The body control module (BCM) monitors the windshield washer pump control circuit. When a front windshield wash is requested for more than 2 minutes, the BCM will turn OFF the windshield washer pump if the front wiper is NOT requested by the wiper switch.

Battery voltage for the windshield washer pump is supplied through the FRT WIPER 25 A fuse and windshield wiper washer switch. Grounding for the windshield washer pump is through the OFF position of the rear washer switch, when equipped.
