High-Speed Operation

With the Wiper Switch in the "HI" position, battery voltage is applied directly to the Wiper Motor, at terminal "A" of connector C2, without passing through the Park Switch contacts. Terminal "A" is connected to a separate Wiper Motor brush for high speed operation. The Park Switch coil remains energized in the "HI" position because of the voltage that is present at the LO speed Wiper Motor brush when voltage is applied to the HI speed brush. The current path from the LO speed brush to the Park Switch coil is completed through the Wiper/Washer Switch. An open in this circuit will cause the wipers to cycle in and out of Park in "HI" and possible prevent "LO" speed operation.

When turned OFF from "HI," the wipers complete the last sweep at LO 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 to terminal "C" of connector C1. The Park Switch is deenergized when the Wiper Switch is moved to "OFF," but the contacts remain closed until the wipers reach the "PARK" position.
