Bonneville V6-3800 3.8L Supercharged (1992)
Strong wind leaks of relatively the same intensity heard at location 1, 2, 3, and 4 in Figure A, are usually associated with an improperly fitting door outer
weather seal. A quick visual inspection will confirm the problem. Any gapping that occurs between the weather seal sealing lip and the door surface can
cause excessive wind noise.
Repair Method:
Remove complete weather seal assembly, using care not to damage paint surface. Inspect clip tangs and reposition any tangs bent during initial
installation and/or removal. Reinstall weather seal by aligning the rear edge of sealing strip to the rear edge of door and engaging (7) clips into slots on
door panel. This is done easiest by inserting the front clip first and working rearward. Again, use caution not to damage painted surface. The weather seal
is fully seated when outer sealing lip is fully compressed on door surface as shown (Figure B). Road test to assure the condition is repaired.
Chart B2 Inner Door Beltline Leaks At Specific Location Only
Strong wind leaks heard at a specific location only on the inner belt can generally be associated with missing or misplaced foam patches at locations 1 or
4 in the figure or a problem with the outside mirror if the noise is intense at locations 2 and 3. Problems with the mirror can be confirmed by inspecting
the mirror for correct positioning of the mirror grommet and the correct installation of the mirror mounting gasket.
