The illustrations contained in this bulletin depict early style (1982-83) components. However, the sealing locations and methods are common on all
years. The RECOMMENDED adhesives and sealing materials are included on those illustrations. (Other adhesives and sealing materials may be
comparable, but only the material specified is recommended). Make sure to protect any interior trim before making any repairs.
Proper lift-off panel and door glass alignments are important to prevent water leaks. If it is determined that the panel and/or door glass require
adjustment, refer to the body portion of the Service Manual. Before adjusting the lift-off panel or door glass, make sure that the door to lock pillar wedge
plates make contact. To check wedge plate contact, apply a piece of masking tape over the lock pillar wedge plate and close door. If the tape is not torn,
additional shim(s) are required and the checking procedure must be performed again after shim(s) are added.
After the necessary repairs are performed, the lift-off panel(s) should be removed and replaced several times to determine if proper alignments are
maintained. Retest the unit with the proper water test equipment to insure a satisfactory repair.
After the final water test, and the vehicle has a satisfactory repair, apply a light coating of paste silicone, GM P/N 1052863, with a clean cloth to all
weatherstrip surfaces in order to prevent squeaks and prolong weatherstrip life.
Labor Time:
1.0 hour diagnostic time -- allowed only once per VIN (includes diagnostic water test, garnish molding removal and installation and
final water test to confirm satisfactory repair only).
This time is to be used in addition to the applicable labor operation used for the repair, proper authorization is required.
