Diagnosis And Testing - Failed Park Switch

DIAGNOSIS AND TESTING - FAILED PARK SWITCH

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 continuously or at low speed for one or more extra wipes.
- LOW SPEED - Wipers operate at low speed.
- HIGH SPEED - Wipers operate at high speed.
- WIPE AFTER WASH - Wipers operate at low speed in any mode setting. Wipers operate only while the wash button is depressed with switch in the OFF mode and 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 table.
