Door Window (Speeds Under 105 km/h 65MPH)
WINDNOISE AT SPEEDS UNDER 105 KM/H (65 MPH)Use the following procedures to diagnose and correct three possible causes of door window air/wind noise at speeds under 105 km/h (65 mph).
Windnoise At Speeds Under 105 Km/h:
Possible Cause #1
There is a gap where the coupe B pillar weatherstrip overlaps the roof weatherstrip (cup gap).
Diagnosis
Road test at speeds less than 105 km/h (65 mph) using a stethoscope or a plastic hose to find the source of the leak.
Correction #1
Grasp the middle of the side of the coupe B pillar weatherstrip with one hand and with the other hand slide the weatherstrip upward in the retainer so it tightly contacts the roof weatherstrip.
Windnoise At Speeds Under 105 Km/h:
Possible Cause #2
There is not enough pressure (4) between the window and the B pillar weatherstrip.
Diagnosis
Road test at speeds less than 105 km/h (65 mph) using a stethoscope or a plastic hose to find the source of the leak.
Correction #2
Adjust the door window tip in so that the window is flush to 2 mm (0.08 in) inboard of the B pillar weatherstrip retainer. Refer to Window Tip in Adjustment - Door in Doors. Doors, Hood and Trunk
Windnoise At Speeds Under 105 Km/h:
Possible Cause #3
There is a gap between the roof panel side weatherstrip and the roof panel weatherstrip retainer at the front or the rear corner of the roof. The air/wind noise sounds like it is coming from an upper corner of the door window.
Diagnosis
Road test at 65 to 80 km/h (40 to 50 mph) using a stethoscope or a plastic hose to find the source of the leak.
Correction #3
1. Remove the roof lift off panel and place the roof panel upside down on a clean dry surface.
2. Remove the screw from the end of the weatherstrip.
3. Partially remove the weatherstrip by carefully peeling the end of the weatherstrip from the top assembly.
4. Apply a bead of urethane based windshield resealant 6 mm (0.2 in) in height.
^ Across the end of the weatherstrip retainer.
^ From the end of the weatherstrip retainer 20 mm (0.8 in) along the upper edge of the retainer.
^ From the end of the weatherstrip retainer 20 mm (0.8 in) along the roof panel at the junction where the roof frame is bonded to the roof panel.
5. Install the weatherstrip and the attaching screw.
6. Clean up any excess sealer with solvent and a clean lint free rag.
Important: When installing the roof panel make sure the front edge of the rear roof bow weatherstrip does not roll rearward and block the drain trough down the middle of the weatherstrip.
7. Install the roof lift off panel.
