Wiper

When the Wiper/Washer Switch is in LO, battery voltage is applied through the GRY wire directly to the low speed brushes of the Wiper Motor. The Wiper Motor runs at low speed.

When the Wiper/Washer Switch is in HI, battery voltage is applied through the PPL wire to the high speed brushes of the Wiper Motor. The motor operates at a higher speed.

The Park Switch is open only when the wiper blades are in the Park position. In all other positions, the Park Switch is closed. When the Wiper/ Washer Switch is moved to OFF, battery voltage at the WHT wire is applied through the Park Switch, the ORN wire, the Wiper/Washer Switch, and the GRY wire to the low speed brushes of the Wiper Motor. The Wiper Motor continues to run at low speed until the wiper blades reach the Park position. At that time, the Park Switch opens and stops the Wiper Motor. The Wiper Motor is protected by a circuit breaker which opens if the current through the Motor rises to a high level. This may happen if the wiper blades are blocked by ice or snow. The circuit breaker resets automatically after it cools off.

Washer

The Washer Motor is energized whenever the Washer Switch is pressed and runs as long as the Washer Switch is closed. Battery voltage is applied through the Washer Switch and the PNK wire to the Washer Motor. The other terminal of the Motor is grounded through the BLK wire.
