General Information

Ignition positive voltage is supplied to the windshield wiper washer switch, windshield wiper motor relay, and the windshield wiper motor position switch from the 30 A WIPER fuse 9 in the fuse block. The windshield wiper motor relay controls the voltage supply used for windshield wiper motor operation during delay, mist, wash, and park modes. The wiper motor supply circuit from the wiper motor relay is routed through the windshield wiper/washer switch where it is spliced to the wiper motor low speed supply circuit.

The windshield wiper motor high and low speed supply circuits are spliced to the body control module and used as signal circuits. When the body control module detects voltage on the high or low speed wiper motor supply circuits the low beam headlamps are turned on.
