GEM controls wiper/washer functions through 3 relays, 2 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.
