Condition

Some customers may comment that the 2nd row center seat belt is not retracting fully or
will not extract from the seat.

Cause

The cause of the condition may be that the seat belt may be twisted within the belt guide,
in the back of the seat.

Correction

Verify the condition, then follow the Service Procedure below to untwist the seat belt and
replace the seat belt opening bezel with a new designed bezel. The new design has a
reduction in the belt opening which will eliminate the belt twisting during retraction.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these
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 your GM dealer for information on whether your vehicle may benefit from the
information.
