DOOR MODULE WATER LEAK APPLY SEALER,INST FOAM/WATER DEFLECT

SUBJECT: WATER LEAK IN THE DOOR MODULE AREA (APPLY SEALER, INSTALL REDESIGNED FOAM SEAL AND WATER DEFLECTORS)

VEHICLES AFFECTED: 1988-91 "C/K" TRUCK

Some owners of 1988-1991 C/K trucks may comment on a water leak at the door module vent valve, at the door module, or between the door trim panel and door onto the primary weatherstrip. The cause of the water leak may be that the door module does not provide a water tight environment.

To correct this condition, it is necessary to apply a sealer (P/N 12345739, sealer) between the door module panel and the air pressure relief valve (Figure 1), to install a redesigned foam seal (P/N 15697102) between the door and door module panel, and install water deflectors (P/N 15697103) to the door module panel.

1. Remove the door trim panel (refer to 'Door Trim Panel Replacement' in the appropriate Service Manual) and water deflector.

2. Remove the six rivets that secure the air pressure relief valve to the door module panel (Figure 1).

3. Apply approximately a 2mm (1/8 in.) bead of silicone sealer (P/N 12345739) around the perimeter of the relief valve.

4. Install six rivets to secure the air pressure relief valve to the door module.

5. Remove the door module mounting bolts.

6. Remove the lock and handle rods from the back of the module and tape the rods to the door.

7. Remove the current foam seal from the door (Figure 2).

8. Install the new foam seal (P/N 15697102) to the door.
