Condition
Some owners of the above listed vehicles may comment on water entering into the rear compartment area.
Cause
Cargo Doors
The following conditions may cause water intrusion:
^
The weatherstrip carrier may be allowing water to enter at the upper radius of the door opening, traveling down to the sill area into the rear
compartment.
^
The rear door may be misaligned at the top, outer edge, causing "overcompression" of the primary and auxiliary seals at the left rear defogger (RPO
C49) switch area.
^
The rear door may be misaligned side-to-side, causing poor contact to the auxiliary weatherstrip at the top of the door.
^
The left rear door vertical weatherstrip mucket (insulator) may not be horizontal on contact with the primary weatherstrip.
Endgate
The current weatherstrip may allow water intrusion at the electrical contact on the left and right side of the rear compartment.
Correction
Cargo Doors
A new rear cargo door opening primary weatherstrip has been developed to correct this condition. This weatherstrip has a mastic (pastelike) sealer in the
carrier that should address the water intrusion provided there are no other existing door conditions. Replace the primary weatherstrip on affected vehicles
using the following procedure and the part number listed below. Some interior trim panels will need to be removed in order to replace the weatherstrip.
Refer to the Interior Trim subsection of the Service Manual.
