Wipers and Washers: Wipers
WARNING: This page is about a different car, the 2010 Lincoln MKX and 2010 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
The wiper system is activated by the multifunction switch. The multifunction 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 assemblies and are not serviceable separately.
