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.

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.
