Incident 1: Upper Windshield

SERVICE PROCEDURE

Incident 1: Wind noise "hiss" or "fluttering" along upper edge of the windshield.

Verify:

1. Test drive the vehicle to verify the wind noise.





2. Apply high quality masking tape to cover the seam between the upper edge of the windshield and the roof (across the upper molding) along the length of the windshield (see Figure 1).

3. Test drive again.

A. If the wind noise is significantly reduced, you have located the source of wind noise and this section applies.

B. If wind noise still exists, this section does not apply, review other incidents identified in this bulletin.

Isolate:

To identify where an air leak exists, insert a business card or feeler gauge between the windshield and the upper molding. Slide the card along the molding to find a loose spot, indicating a potential leak.

Repair:

1. Remove windshield top and side moldings.

CAUTION: These moldings will be re-installed, be careful not to damage them.

2. Clean the windshield edges.

3. Apply a suitable glass sealant (3M Black Silicon Sealant P/N 051135-08662 or equivalent) to the upper edge of the windshield.

4. Re-install the moldings.

5. Wipe off excess windshield sealant.

Recheck:

Test drive the vehicle and confirm that the noise from the upper edge of the windshield no longer exists.
