Condition # 3

Condition #3

Some customers may comment on wind noise/wind rush type noise coming from outside of the vehicle in the sunroof module seal to roof area.

Cause #A

This condition may be caused by a lack of seal compression from the sunroof module to metal roof.

Cause #B

A rolled seal and/or a puckered seal at one of the corners at the module.

Cause #C

Correction A and Cause B do not correct the windnoise.

Correction A

Lack of Module Seal Compression to the metal roof

1. Verify the noise condition, visually inspect the entire perimeter of the module seal for improper/uneven seal compression and/or gaps to the metal roof.
2. Using masking tape, tape across the suspected poor sealing area from the roof metal to the seal. Test drive and verify the noise is gone. If the noise is gone follow the appropriate procedure below. If the noise is still present, repeat steps 1 and 2 as required.

Figure 14





- If the noise is coming from the front center of the sunroof module (refer to figure 14), loosen all front 4 module mounting bolts (refer to figure 1). Verify that the compensators are not engaged into the roof. Spin all front four compensator barrels all the way down (refer to figure 3).

Important
To achieve proper seal to body compression, have one person push firmly upward on the black rail of the module between the two front center screws as another person tightens the center two screws (refer to figure 4). This will improve the seal contact along the front edge of the module to body. Then reinstall the two outboard tolerance compensators to the roof. (Torque specification 10 Nm/89 lb in) (refer to figure 4A).

Figure 15





- If the noise is coming from the side center of the sunroof module (refer to figure 14), loosen the three side mounting bolts (refer to figure 15). Verify that the compensators are not engaged into the roof. Spin all the three compensator barrels all the way down (refer to figure 3).

Important
To achieve proper seal to body compression, have one person push firmly upward on the center of the side black rail of the module as another person tightens the center compensator (refer to figure 15). This will improve the seal contact along the side center edge of the module to body. Then reinstall the other two side outboard tolerance compensators to the roof. (Torque specification 10 Nm/89 lb in).

Figure 16





- If the noise is coming from the one of the four corners (refer to figure 14), adjust the proper corner leveling nut (height adjusters) accordingly (19 mm hex heads) (refer to figure 16).

Important
When you loosen the nut, you are tightening the seal to roof, creating a better module to roof seal. When you are tightening the nut, you are loosening the seal to roof.

3. Verify the front of first glass is flush to -1 mm below the roof (refer to figure 12). If the front of 1st glass is higher than the roof, readjust the front of first glass using the procedure described in the Glass Panel Adjustment Procedure (Condition #2).

Condition B

Verify seal fit consistency to the entire perimeter of the roof.

Repair rolled perimeter seal by spooning into position with "Trim Stick" or credit card type tool.

Incorrect position rolled seal.





Pull seal out from under roof edge with trim stick.





Corrected position.





Push seal back under roof edge with trim stick.





Corrected position.

Important
Test drive vehicle and verify condition is gone.

Notice
In some instances, over longer periods of time and sun exposure, the seal may take a permanent set. In these types of cases, the seal may have to be replaced (see Correction C below).

Correction C

Important
The sunroof module seal is available as an individual service part. DO NOT order an entire sunroof module to get the seal.

Replace the sunroof module seal.

If Correction A & B don't correct the condition replace the seal with P/N 25866123 and adjust the front glass panel properly (refer to Sun Roof Window Alignment in SI).

Important
When installing the new seal, DO NOT remove all glass panels. Remove only the first and last glass panels, with the sunroof in the open position, remove the old seal and install the new seal working your way around the perimeter of the roof. This will avoid the need to totally readjust all four glass panels. Use the ignition key to properly place the panel in the appropriate position to properly install and seat the seal.

After installing the module seal, reinstall and properly adjust first and last glass panels. Operate the sunroof to ensure proper operation. Test drive vehicle to make sure no noise issues are present.
