2. Push down on the lever several times (pumping
movement) with high force even when the seat is in
the lowest position, then pull the lever up with high
force.
Important: Do NOT loosen or disassemble the
attachment nuts on the height adjust mechanism that is
attached to the cushion seat frame.
Important: This will solve the jamming of the gears
and seat is adjustable again.
Note: The lever and pump assembly can resist this
force easily and will NOT be damaged during the
process.
3. Once the mechanical function becomes
un-jammed, cycle the height adjuster handle to full
up and then full down 4 times for additional
break in.
4. If unsuccessful, then follow normal service
procedure for cushion frame replacement.

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.
