ERRATIC MEMORY SEAT OPERATION REPLACE SEAT MOTOR

ERRATIC MEMORY SEAT OPERATION

VEHICLES AFFECTED: 1985-1988 C ------------------

Some 1985-1988 C-Cars equipped with memory seats may experience a condition of the seats not moving to the programmed seat position. This will occur in both memory 1 and memory 2 settings. This condition may be caused by a power seat motor sending a "noisy" signal to the memory seat module, which will result in any one of the three power seat motors losing or gaining distance with each successive use of the memory.

To repair this condition replace the motor assembly, part number # 20560003. Refer to Section 9C of the appropriate Body Service Manual for the replacement procedure.

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.
