INNER DOOR BELTLINE LEAKS AT SPECIFIC LOCATIONS 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.
Repair Method:
Locations 1 or 4: The correction to noise at these locations is to carefully stuff small patches of soft foam in the openings between the inner belt weather
seal lip, the door garnish moldings and the interior trim pad. Do not put foam between the lip and the dropping glass on the rear of the front doors or the
front of the rear doors, as it will simply tear away when the glass is dropped.
Locations 2 and 3: If inspection identifies that the grommet or the base gasket is incorrectly installed, correct the problem and road test for improvement.
If the mirror does not turn up a problem source, re-evaluate the outer belt weather seal for gap to the door surface. Correct as outlined in Chart B1.
