WATER INTRUSION INTO THE PASSENGER COMPARTMENT. Pontiac J2000 1983

For 1990-2009 cars

# WATER INTRUSION INTO THE PASSENGER COMPARTMENT

Some conditions where water may enter into the passenger compartment through the HVAC ducts have been received.

This water entry condition may be caused by the windshield washer container interfering with the HVAC plenum drain valve causing water to collect in the plenum and back up into the air intake.

To correct this condition, remove the windshield washer container and elongate the outboard bottle mounting hole as shown (see illustration).

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.
