SUBJECT:
Wind Noise
OVERVIEW:
This bulletin involves checking and/or sealing the A-pillar cavity, front door body mounted weatherstrip, door flag speakers, **sunroof** and windshield wipers.
SYMPTOM/CONDITION:
Wind noise heard from the **sunroof** or B-pillar forward in the vehicle while driving at highway speeds above 55 mph or at lower speeds into a headwind.
DIAGNOSIS:
Perform the wind noise diagnostic procedure on page 23-32 of the 2000
Concorde/Intrepid/LHS/300M Service Manual (Publication No.81-270-0040). If this
procedure and related repairs do not resolve the condition, perform the Repair Procedure.
Required Parts :
REPAIR PROCEDURE:
Procedure A
1. Remove the instrument panel end cap.
2. Remove the A-pillar trim.
3. Apply a thumb grade sealer, Mopar Butyl Tape, p/n 04076274, or equivalent to completely close the hole at the base of the A-pillar (Figure 1).
4. Install A-pillar trim and end cap.
5. Repeat procedure on other side of vehicle as necessary.
Procedure B
1. If wind noise improvements were noted during diagnosis when the gap between the front door and body were taped off, replace the front door body mounted weatherstrips as described on page 23-51 of the 2000 LHS/300M/ Concorde/Intrepid Service Manual (Publication No.81-270-0040).
Procedure C
1. There should be a visible gap (not touching) between the front edge of the front window flag speakers and the front door body mounted weatherstrips (Figure 2). If a gap exists proceed to Procedure D. If no gap exists proceed to step 2.
2. Make sure the weatherstrip is fully seated on to its mounting flange. If the interference still exists, remove the two speaker enclosure attachment screws and remove the enclosure.
3. Remove the two speaker attaching screws and remove the speaker.
4. Loosen the two screws that attach the speaker mounting plate to the door. Reposition the plate rearward and reinstall the speaker and enclosure.
5. If the interference still exists, remove the speaker mounting plate and slot the mounting holes 1-2 mm (1/16 in.) in the fore-aft direction to provide additional adjustment. Reassemble plate, speaker, and enclosure.
6. Repeat procedure on other side of vehicle as necessary.
Procedure D
1. Check the position of the windshield wiper assemblies in the park (off) position. If the wipers are above the positioning ('tic") marks on the windshield adjust as necessary (Figure 3).
**Procedure E
1. Check the gap around the perimeter of the sunroof between the seal and the roof aperture. The seal should make contact all around and there should be no gap. Dragging a business card (~0.3mm thick) around the perimeter should be provide uniform resistance.
2. If there is a gap or low drag resistance at the front, or rear, edge of the glass, loosen the four attaching screws so that glass can be adjusted (Figure 4). Reposition the glass panel so that it is evenly spaced front to back and again recheck the drag on the business card. Readjust until the front to back gap is uniform.
3. Tighten the four attaching screws to 5.5 Nm (50 in. lbs.).
4. Cycle the sun roof and check the glass flushness.
