Owners of some 1991-92 Bravadas may comment that their vehicle exhibits a condition where the seat back assembly has movement or a rattle which is perceived to be an improperly latched seat assembly.
The seat is designed with a cable-released latch on the left side and an inertia latch mechanism on the right side. The inertia latch mechanism allows movement of the right side of the seat unless a high deceleration stop, due to braking or a frontal impact, is experienced.
In an effort to improve overall customer satisfaction, a revision has been made to the design that provides a cable release latch to both the right and left sides of the rear seat back. The dual cable release mechanism was incorporated in vehicles built after vehicle number N2704546.
If a customer experiences this condition and expresses concern even after the latch operation is explained, the dual cable release mechanism may be installed in vehicles built prior to the breakpoint listed above.
To install the dual cable release, follow instruction sheets provided in the kit (P/N 15693919). If the seat back is difficult to release after the kit is installed, it may be necessary to increase the clearance of the seat back to the wheelhouse. This can be accomplished by the installation of two 2mm (1/1 6 in) spacers (P/N 20432548). Install 1 spacer over each of the left hinge mounting studs between the floorpan and the seat hinge. Verify correct seat latch operation after spacer installation.

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.
