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: (Figures 1-4)

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. (Figure 1)

2. Remove and discard the bulkhead connector engine harness cover located on the RH side of the connector (most inboard). (Figure 1)

3. Inspect, clean and replace any corroded terminals. (Figure 2)

4. Apply a heavy coat of lubrication, GM P/N 1052497 (Chassis Grease), filling all cavities and thoroughly sealing all cable termination points. (Figure 3)

5. Reinstall the bulkhead connector and apply lubrication around all engine harness wires where they enter the bulkhead connector. (Figure 4)

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
