Should comments be received from owners of 1988 or 1989 Skylarks 4-door sedan model having a front seat that folds forward, as is the case with 2-door coupe seats, it is possible that the 2-door front seat control assembly was installed in the 4-door seat during production.
A new 4-door seat back control assembly can be installed in the seat should the owner wish to have it changed. The following information may be helpful when ordering the correct seat back control assembly from GMSPO.
Usage Control Assembly ----- ---------------- 1988-1989 4 door Passenger: 20718232 Driver: 20718233
1988-1989 2 door Passenger: 16602620 Driver: 16602621
Parts are currently available through GMSPO.
The current edition of the GMSPO catalog INCORRECTLY identifies the usage of part number 16602620 and 16602621 for 2-door and 4-door Skylarks. Usage is for 2-doors only. This correction will be made in the next edition of the catalog.
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.
