under this bulletin, including but not limited to
handling, deploying, preparing, classifying,

3. Once the clip is in the interface, use a flat-head
screwdriver to ensure the clip is snapped on the
shoulder of the bolt.
Note: The clip is designed to have a tight/interference
fit in the joint. Since the gaps available could vary from
seat-to-seat, it is recommended to apply cross-car load
in the direction shown, in order to aid the installation
process. Load required to create a gap should be less
than 150N.
Note: Please ensure the clip is fully seated. Clip
‘snaps’ in position when fully seated.

4. With the clip installed, try to duplicate the customer
concern and verify the cross-car looseness is no
longer present.
5. With the seat in upright condition, function the seat
with the recliner handle to ensure the seat stows
unassisted to fold flat position. If the seat stalls,
please perform service rework procedure per the
latest version of bulletin 21-NA-129.

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.
