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


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.


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.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
