The door check strap on 1984-86 G Vans equipped with RPO E24, swing-out side cargo doors, was designed with a detent position at 90 degrees. However, the detent on some door check straps may be inoperative and permit the cargo door to travel beyond 90 degrees and contact the body of the vehicle. To address this condition, a new side door check strap that restricts the travel of the cargo door to 90 degrees has been released. If door travel beyond 90 degrees is required, the check system can be disengaged to permit full 160 degrees door travel. The instructions for disengaging the check system are on a label affixed to the check strap.
The service procedure and parts required to modify the swing-out side cargo door are as follows:

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.
