High Speed

With the Wiper Switch in the "HI" position, battery voltage is applied directly to the Wiper Motor, at CKT 92, without passing through the Windshield Wiper Motor Park Switch contacts. CKT 92 is connected to a separate Wiper Motor brush for high speed operation. The Windshield Wiper Motor Park Switch coil remains energized in the "HI" position because of the voltage that is present at the low speed Wiper Motor brush when voltage is applied to the high speed brush. The current path from the low speed brush to the Windshield Wiper Motor Park Switch coil is completed through the Windshield Wiper/Washer Switch. An open in this circuit will cause the wipers to cycle in and out of Park in "HI" and possibly prevent "LO" speed operation.

When turned off from "HI," the wipers complete the last sweep at low speed and park. To do this, the Wiper Motor receives voltage in the "OFF" position of the Wiper Switch, which is applied through CKT 95. The Windshield

Wiper Motor Park Switch is de-energized when the Wiper Switch is moved to "OFF," but the contacts remain closed until the wipers reach the "PARK" position.
