The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Condition/Concern:

Some customers may state that the wipers will not park after using the wipers in any position. The customer may also notice that when using the mist button, the wipers will stop when the switch is released and mist function will not continue to wipe windshield and park.

Recommendation/Instructions:

Check the wiper on/off relay (relay #45) in the Underhood Buss Electrical Center (UBEC) and make sure that the relay is properly secured into the socket of the UBEC. If the relay is secured, try a good known relay from a good known vehicle and replace as needed.

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
