WATER LEAKS FROM VENT DOORS HOOD HINGE SEALS INSTALLATION

MODELS: 1982-83 S/T TRUCKS

Water entry into the passenger compartment from the vent doors on subject vehicles may be caused by mispositioned or torn hood hinge seals. This water intrusion can be the result of the hood hinge seal not diverting rain water as intended and allowing it to fall over the vent door and into the air stream.

A revised production seal has been released for vehicles built after February, 1983. This seal is now available for service.

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.
