WATER LEAKING INTO PASSENGER COMPARTMENT (APPLY RTV SILICONE SEALER TO TOP VENT GRILLE ASSEMBLY)
Model(s): 1996-98 Buick Skylark
1996-98 Oldsmobile Achieva
1996-98 Pontiac Grand Am Section: 10 - Body Bulletin No: 73-10-68 Date: April, 1998
Some owners may comment on water leaking into the passenger front floor area.
Condition may be due to poor adhesion of the top vent grille assembly to the windshield. The existing seal tape can separate from the glass or the grill above the A/C air intake canister and allow water to overflow into the passenger front floor area.
Remove the top vent grille assembly. Clean the grille assembly and the surface of contact on the windshield of all sealing tape and adhesive residue. Apply a bead of RTV Clear Silicone Sealer from 3M(R), Part #08662, or equivalent, to the underside of the top vent grille assembly where the old seal tape was removed. Reinstall the grille. Wipe excess RTV Sealer horizontally across sealing area to achieve a smooth finish.
