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.
