13054 - Customer Satisfaction Program. The windshield may not be completely sealed to the body at the lower left side of the windshield. Water could leak into the vehicle at this point and drip onto the body harness connector, causing corrosion on the terminals or shorting between terminals. Depending on the terminal(s) involved, it could cause one or more of the following conditions: automatic OnStar® emergency calls, flashing of the park brake light, rough engine operation, improper air conditioning system operation, illumination of the Service Engine Soon light, and other malfunctions. Dealers will perform a water test to detect a water leak. If a leak is found, dealers will reseal the area and perform another water test. If leaking is still present, the windshield will be reinstalled. If evidence of a leak is found, the connectors will be inspected to determine if any terminals are corroded. Corroded terminals will be replaced.
