Windshield Washer
WARNING: This page is about a different car, the 2016 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.
When the washer switch on the end of the multifunction switch is pressed, the windshield wiper motor activates the wipers and the wash relay (internal to the windshield wiper motor), providing voltage to the washer pump and directing washer fluid to the windshield. When the switch is released, the windshield wiper motor continues to activate the windshield wipers for 3 additional wipes and then turns the windshield wipers off.
