Wind Hiss Noise Around A-Pillar

Verify:

There may be a wind hiss noise around the A-pillar, from the base to the top of the windshield. The incident is usually more pronounced during cross wind gusts.

Incident can be identified by taping over the entire length of the windshield side molding, along the A-pillar (do not obstruct the test driver's vision). If the noise stops use the following procedure to resolve the incident.

Isolate:

The gap between the windshield and the side molding may vary from vehicle to vehicle. The larger the gap, the more prone the vehicle is to this incident. Install foam seal into the windshield side molding using the repair procedure below to resolve the incident.

Repair:

Figure 7:

1. Remove drip rail weatherstrip from bottom of A-pillar to the top of the roof line (see Figure 7) to uncover windshield side molding.

2. Remove four screws from the side windshield molding.

3. Carefully remove the side windshield molding off of the vehicle.

Figure 8:

4. Cut a piece of foam tape (3M Scotchfoam P/N 021200-03320 Tape # 4504 or equivalent) approximately 55cm (21.65in) long, 10 mm (0.39in) wide, and 15 mm (0.59in) thick. Attach this piece to the inside of the groove of the side windshield molding between the two pieces of foam (see Figure 8).

5. Reinstall in reverse order of disassembly.

6. Apply suitable adhesive (3M Super Weatherstrip Adhesive P/N 051135-080084504 or equivalent) to underside of drip rail weatherstrip at the bottom of A-pillar area to attach the end down.

Recheck:

Test the vehicle as described in "Verify" above to ensure the repair is complete.
