Without Pulse

When the Wiper Switch is in LO, battery voltage is applied to the Wiper Motor Assembly through the GRY wire. The Wiper Motor will run at low speed until the Wiper Switch is turned to the OFF position.

When the Wiper Switch is turned to OFF, the Run/Park Switch is still in the RUN position. Voltage is still applied to the Wiper Motor at the low speed brush through the Run/Park Switch, the ORN wire, and the GRY wire. The Wipers complete the last sweep in low speed. When the Wipers reach the Park position, the Run/Park Switch opens, shunting the Wiper Motor, causing it to stop immediately. The Wipers remain in the Park position.

when the Wiper Switch is in HI, battery voltage is applied to the Wiper Motor Assembly through the PPL wire to the high speed brush. The Wipers make the last sweep in low speed and park similarly to low speed operation.

The Wiper Motor is protected by a self-resetting circuit breaker. The circuit breaker opens if the Wipers are blocked. The circuit breaker resets automatically when it cools.

When the Wiper Switch is moved to MIST and released, the Wipers make one sweep at low speed and return to Park. The circuit operation is the same as low speed.

When the Wash button is pressed, battery voltage is applied to the Washer Pump and the Wiper Switch is mechanically advanced to the LO position. The Washer sprays the windshield as long as the switch is held ON. The Wipers must be turned off manually after the wash cycle.
