DTC B3713
CIRCUIT DESCRIPTION
The body control module (BCM) monitors the rear window washer switch signal circuit. When a rear windshield wash is requested for more than 2 minutes, the BCM will turn OFF the windshield washer fluid pump motor if the rear wiper is NOT requested by the windshield wiper washer switch.
Power for the windshield washer fluid pump is supplied through the FRT WIPER 25 A fuse and windshield wiper washer switch. Grounding for the windshield washer fluid pump is through the OFF position of the windshield washer fluid pump.
