Incident 2: A Pillar

Incident 2: Wind noise. "hiss" or "fluttering", along the A Pillar.

Verify:

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




2. On both sides of the vehicle, apply high quality masking tape to cover the seam between the windshield and the A pillar (across the side molding) along the height of the windshield (see Figure 2).

3. Test drive again.

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

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

Isolate:
The cause of the wind noise is the windshield side moldings.

Repair:

1. Remove both windshield side moldings.

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

2. For each one of the side moldings, cut two pieces of foam seal (3M Scotchfoam P/N 051131-06370 Tape No.4504 or equivalent). Cut the first piece approximately 60 cm (23.6 in,) long, 10 mm (0.4 in.) wide and approximately 8 mm (0.3 in.) thick. Cut the second piece approximately 25 cm (9.8 in.) long, 10 mm (0.4in.) wide and approximately 8 mm (0.3 in.) thick.





3. Attach the longer foam strip inside each of the side moldings (see Figure 3). Attach the shorter foam strip at the thicker end of each of the side moldings as shown in Figure 3. The foam seal will absorb any wind noise created inside the side moldings.

4. Re-install the side moldings.

Recheck:
Test drive the vehicle and confirm that the noise from the A pillar no longer exists.
