SUBJECT:

Wind-Like Sound At Side Door


OVER VIEW:

This bulletin involves a discussion of possible sources and corrections of wind-like sound at the front or rear side door.


MODELS:


2007 (HB/HG) Durango/Aspen


DISCUSSION:

1. Road test the vehicle to determine if the source of the wind-like sound is from one of the side doors.

2. If the wind-like sound is from a side door, determine if the sound is from the door seal or from the window seal.

a. If the source of the wind-like sound is from the door seal, then proceed to Section A

- Door Seal and Surface.

b. If the source of the wind-like sound is from the window seal, then proceed to Section B - Window Glass Run Seal

Section A - Door Seal and Surface:


1. Wide Seal Gap - the distance between the door frame surface and the body pinch weld (flange) surface may be too large for the door primary seal to seal properly. Check the gap between the door frame and the body by:

a. Remove the door primary seal to expose the body pinch weld (flange).

b. Lower the door window.

c. Close the door.

d. Standing outside the vehicle, and through the open window, measure the gap between the door frame surface and the body flange (pinch weld) surface. Measure at several locations. Record your measurements.

e. If the gap between the two surfaces (door frame and body flange) is greater than 16.5 mm, then the door frame needs to be moved inboard to reduce the size of the gap.

f. If the gap is less than 16.5 mm, then install the door primary seal and proceed to the next step.
2. Door Primary Seal - the seal may not be installed properly or may be damaged. In both cases, the seal may not be touching down on the door and could create a potential leak path for air. Check the door primary seal by:

a. Open the door and inspect the entire primary door seal.

b. Look for any damage or deformation of the primary seal.

c. Determine if the primary seal is fully seated and properly positioned to the body flange.

d. Remove the seal and reinstall the seal onto the body flange.

e. If the wind-like sound is still present, and the sound is from the door seal and not some other source, then replace the suspect door primary seal.

Section B - Window Glass Run Seal:


1. Verify that the window glass run seal is correctly installed.

2. If the glass run seal is installed correctly, then a cost effect fix is to add a non-hardening mastic sealer in the area of the sound. The mastic sealer will block the air from leaking past the glass run seal and will also eliminate the need to replace the entire glass run seal.

a. Rear door fixed glass seal - pay particular attention to the top rear corner of the fixed glass, left side rear door especially.

b. Dependent upon the location of the air leak source, add the mastic sealer between the backside surface of the seal and the window channel door panel.
