Condition

-
The carpet is wet in the rear area of the vehicle.
-
There is condensation on the windshield or side glass.

Cause
Important
Some vehicles may have been revised at the factory with the use of ribbon sealer in the area where the top bed rail seal joins the rear window
opening seal. It is important to maintain this revision during the repair procedures. If the revision material needs to be added to or replaced use
a 9.5 mm Butyl Ribbon Sealer, such as 3M P/N 08612 or equivalent. Refer to the opposite side of the repair vehicle to illustrate how the sealer is
applied.
-
Insufficient seal pressure between the upper midgate glass panel and the body opening weatherstrip.
-
Incorrect alignment of the midgate to the body.
-
Insufficient seal pressure between the tonneau or cargo cover and the midgate cross bar.
Water Test Procedure
1. Assure that the midgate cross bar is completely closed. Inspect the latches on both sides.
2. Assure that the arrow on the mid glass is aligned with the arrow on the cross bar.
3. Verify that the interior trim is not putting pressure on or overlapping the upper weatherstrip, causing a poor seal.
4. Ensure that the weatherstrip mucket (bat wing) is glued to the weatherstrip (1).
5. If the mucket is not glued as shown, use the following glue procedure.
-
Remove the weatherstrip as required to access this revision.
