Failed Park Switch Test

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 table.
