Windshield Washer

When the wiper/washer switch is pulled towards the driver, the SASM sends the windshield wash request to the BCM over the LIN. The BCM activates the windshield washer relay (internal to the BCM) and the windshield wiper on/off relay. When the BCM activates the windshield washer relay, voltage is provided to the washer pump, directing washer fluid to the windshield. When the wiper/washer switch is released, the windshield wiper motor continues to activate the windshield wipers for 3 additional wipes and then turns the windshield wipers off.
