Wiper/Washer System Description and Operation: Notes

The windshield wiper system consists of a wiper motor, a linkage, a wiper arm and blade, and a wiper/washer switch. The windshield wiper circuit incorporates a self parking device which consists of a worm gear and a cam plate in order to keep the circuit complete temporarily when the switch is turned OFF. The wiper system is driven by a permanent magnet-type motor. The windshield wiper motor is mounted on the dash panel and is directly connected to the windshield wiper linkage.

The windshield wiper motor has two speeds, LO and HI, and intermittent wiper capability. The wiper switch is an integral part of the wiper/washer switch. Windshield wiper operation is actuated through the lever on the right side of the steering column.
