WARNING: This page is about a different car, the 2008 Ford RV Cutaway, 2008 Ford Econoline, 2008 Ford E450 Super Duty, and 2008 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
The windshield wiper/washer switch is an integral component of the steering column multi-function switch. The multi-function switch provides input to the wiper motor module to activate wash, low, high and intermittent modes. The relays are all integral to the wiper motor module assembly and are not serviceable separately.
The washer system consists of the washer reservoir and washer pump. When the multi-function switch is placed into the wash mode, the windshield wiper motor integral electronics activate the washer pump to direct washer fluid to the windshield.
