Due to revisions in the affected model years, this bulletin supersedes bulletin 91-T-30A, which should be discarded.
CONDITION: Water may enter at sides of roof panel flange where outer and inner roof panels are welded together or at roof side drip molding clips where they attach to the roof panel. Customer may comment that the leak develops after the vehicle is subjected to an extended rain. The leak may not occur during a brief rain or in a car wash.
CAUSE: An opening may exist between the inner and outer roof panels in the space between the welds connecting these panels. Water may enter this opening and/or around the roof side drip molding clips and flow toward the front of the windshield, where water may leak down the inside of the glass.
CORRECTION: Perform the following procedures to locate the area where the water is entering the vehicle
--------- 1. Refer to "Waterleaks" in the "General Information" section of the "Body/Collision Repair Service Manual." Perform the "Waterleak Diagnosis and Repair" procedures to locate a leak around the windshield area. If a leak is detected, paddle in extra adhesive using a flat flexible tool and adhesive from Adhesive Kit P/N 12345633 (or equivalent urethane adhesive). Verify that leak is fixed.
2. If no leak is found using the above procedures and there is evidence of a previous waterleak in the front corners of the headliner, remove the roof drip molding for either the Sedan or Coupe, according to procedures under "Roof Drip Molding" in the "Doors" section of the "Body/Collision Repair Service Manual."
3. Apply Kent Industries Leak Chek (Black), P/N 10510 (or equivalent) to the entire length of the roof flange. Use a flat flexible tool and apply where the outer and inner roof panels are welded together, as shown in illustration. Be careful not to get sealer on other parts of the vehicle.
4. Apply sealer around all of the roof side drip molding clips as shown in illustration.
5. Install the roof drip molding according to procedures under "Roof Drip Molding" in the "Doors" section of the "Body/Collision Repair Service Manual."

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.
