Windshield Washer
WARNING: This page is about a different car, the 2016 Ford Transit-350 HD, 2016 Ford Transit-350, 2016 Ford Transit-250, and 2016 Ford Transit-150. However, it is still accessible from the selected car via links, so may be relevant.
When the washer switch is pulled towards the driver, the SASM sends the windshield wash request to the BCM over a 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 BCM continues to activate the windshield wipers for 3 additional wipes and then turns the windshield wipers off.
