The following diagnosis might be helpful if the vehicle exhibits the symptom described in the PI.

A customer may complain of intermittent or inoperative functions of the following components: windshield wipers, trunk release, radio, turn signal lamps, power mirrors, air bag, door locks, stop lamps, accessory fuse, hazard lamps, heater, air conditioning, HVAC, power seat. A water leak on the drivers side of the vehicle, the drivers side carpet being wet or water dripping from the park brake release handle area on to the floor could be the cause.

A water leak from the windshield will travel down the left a-pillar and drip on the left I/P fuse panel, and depending on the weight of the front seat driver or passenger, the water leak can be on the right side of the windshield and will travel down the right a-piller, across the front of dash area to the left side of the vehicle, and drip on the left I/P fuse panel. When diagnosing an interior water leak concern, a disconnected sun roof drain hose should also be inspected when the water appears to be coming from the drivers side of the vehicle.

Reseal the windshield and repair or replace any corroded wire(s) or connector(s).
