Front Wiper and Washers
WARNING: This page is about a different car, the 2003 Mercury Sable and 2003 Ford Taurus. However, it is still accessible from the selected car via links, so may be relevant.
The multifunction switch controls the front wiper/washer portion and is wired to the GEM. When the switch is moved to the desired position the GEM processes this information and energizes one of two relay coils which control the front wiper motor speeds. In order to achieve high speed operation, both relays are energized. The GEM will respond to the wiper switch inputs only when the ignition is in RUN or ACC. The front washer pump relay is hard-wired to the GEM which will actuate the pump when the front wiper/washer switch portion of the multifunction switch is engaged, for up to 10 seconds.
