Some of the subject M vans may experience a seat belt fouling condition on the door openings causing damage to the door trim panel and/or door opening when closing the door.

This condition, if experienced, may be corrected by replacing the seat belt assembly. The revised seat belt assembly has a modified shoulder belt stop location. The new seat belt assembly was released as standard equipment effective in production April 3, 1989. A seat belt assembly with this new feature can be installed by ordering:

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.
