THIS BULLETIN CANCELS AND SUPERSEDES DEALER SERVICE BULLETIN NO. 89-287-8C, DATED JANUARY 1990. THE LABOR TIME HAS BEEN CORRECTED. ALL COPIES OF BULLETIN NO. 89-287-8C SHOULD BE DISCARDED.

1988-1989 G1, G2 and G3 vans could experience the above subject conditions due to bulkhead connector corrosion. Water entry into the engine compartment through the hood seal hinge slot can affect the integrity of the bulkhead connector.

To address this condition, it is necessary to apply lubrication in and around the bulkhead connector.

REMOVAL AND REPLACEMENT PROCEDURE:

1. Loosen the 1/4" hex head screw located in the center of the bulkhead connector and disconnect the connector. The bulkhead connector is attached to the cowl on the LH side of the engine compartment.

2. Remove and discard the bulkhead connector engine harness cover located on the RH side of the connector (most inboard).

3. Inspect, clean and replace any corroded terminals.

4. Apply a heavy coat of lubrication, GM P/N 1052497 (Chassis Grease), filling all cavities and thoroughly sealing all cable termination points.

5. Reinstall the bulkhead connector and apply lubrication around all engine harness wires where they enter the bulkhead connector.

Parts are currently available from GMSPO.
