Incident 4: Front Door Top Edge

Incident 4: Wind noise "hiss" along the top edge of the front door glass.

Verify:

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





2. Apply high quality masking tape, from the door, across the run rubber, to the top edge of the door glass (see Figure 6), covering the seam in between.

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 a leak exists, try either of the following methods.

1. Roll the window up completely. From the outside, insert a business card or feeler gauge between the window and the run rubber. Slide the card along the run rubber to find a loose spot, indicating a potential leak. Repeat on the inside of the door.

2. Roll the window half-way down. Spray the top outside and inside edges of the window with powder spray (Crest Leak-Trace, Stock No. AT-R or equivalent). Roll the window up completely and then back down. An un-smeared spot will indicate a potential leak.

Repair:

1. Remove the run rubber from the door frame.

CAUTION: The run rubber will be re-installed, be careful not to damage it.





2. Cut a piece of foam seal (3M Scotchfoam P/N 051131-06370 Tape No.4504 or equivalent), 20 cm long (approximately 8 inches) and 7 mm wide (approximately one-quarter inch wide). Attach this strip along the interior side of the run rubber (as shown in Figure 7). This will increase the contact pressure between the window and the exterior side of the run rubber.

3. Re-install the run rubber.

Recheck:

Test drive the vehicle and confirm that the noise from the front door glass no longer exists.
