ALL CHEVROLET DEALERS
The door glass inner seal may become detached from the door panel due to an incorrect attachment procedure used in production (see Figure 1).
Excessive air stapler pressures allow the attachment flange of the seal to tear as the window is cycled. This has been corrected in production.
If separation occurs, the condition can be corrected by replacement of the seal, serviced under the following part numbers:
15603485 - Left 15603486 - Right
NOTE:
It is NOT necessary to replace the entire door panel assembly. The following procedure is recommended to re-attach the seal:
FIGURE 2
1.
Remove the door inner panel.
2.
Remove the existing seal (if partially attached), and extract the production installed wire staples.
3.
Locate the new seal by using the locator hole on the door panel and the barb on the back side of the seal flange (see Figure 2). Temporarily clamp
