High Speed Windshield Wipers

High speed operation is activated when the multifunction switch supplies a ground to the high speed inputs of the smart junction box (SJB). When the SJB receives ground from the multifunction switch, the SJB activates the run/park and high/low relays by grounding the relay coils. When the wiper run/park and wiper high/low relays are activated, the wiper run/park relay supplies voltage to the high speed output of the wiper high/low relay. The SJB continues to cycle the windshield wiper in high speed mode until the inputs from the multifunction switch are changed from the high speed position.
