Failed Park Switch

Wiper System Diagnosis:

If the wiper park switch has failed the windshield wipers will operate as follows:
SWITCH OFF - Wipers stop in current location regardless of the park signal.

INTERMITTENT MODE - Wipers operate at low speed for one or more extra wipes or continuously

LOW SPEED - Wipers operate at low speed.

HIGH SPEED - Wipers operate at high speed.

PULSE WIPE - Wipers will not operate.

WIPE AFTER WASH - Wipers operate at low speed in any mode setting. Wipers operate only while wash button is depressed with switch in OFF mode, wipers stop in mid-cycle when button is released.

The windshield wiper park switch and circuit is monitored by the BCM. The park switch and circuit can be tested using the Wiper System Diagnosis chart.
