WARNING: This page is about a different car, the 1997 Mercury Sable and 1997 Ford Taurus. However, it is still accessible from the selected car via links, so may be relevant.
All wiper/washer functions are controlled by the multifunction switch and the Generic Electronic Module (GEM) located on rear of fuse junction panel. GEM controls wiper/washer functions through 3 relays. Two relays control wipers and the third relay controls windshield washer. One wiper control relay switches between High (HI) and Low (LO) speeds. The other wiper relay switches between run and a dynamic brake (armature short circuit) and is used in Interval (INT) mode of operation. Interval delay is controlled by control knob on end of multifunction switch lever.
