Washer Operation

When the Windshield Wiper/Washer Switch is depressed, voltage is supplied to the solid-state control board. The control board supplies battery voltage to the Windshield Washer Motor pump through the RED (228) wire. It also starts the wiper cycle through the low speed brushes of the Windshield Wiper Motor Module. The washer continues to run as long as the switch is held down. The solid-state control board keeps the wipers on for approximately six seconds after the washer goes off. If the washer is switched on during the PULSE operation, the wipers run in low speed for six seconds. The wash cycle is completed before the wipers return to the delayed pulse operation.

The Windshield Wiper Motor Module is equipped with a circuit breaker which protects the motor when the wipers are blocked. The resulting high current will open the circuit breaker which will reset upon cooling.
