---------- The memory seat may lose horizontal position on recall. Position loss is usually between 1/2 inch to 2 inches per recall. This may occur with the seat empty or occupied.
------- Grease, used in the horizontal flexshaft cover to quiet audible noise, is leaking into the horizontal drive motor. This causes a distorted signal from the motor to the memory module. The distorted signal causes the memory module to stop horizontal recall motion early.
------------ Replace the outboard horizontal flexshaft and cover assembly, part number #20515599. This assembly must not be re-greased. The grease is not required for lubrication. Replace the horizontal drive motor, part number #20560003.
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.
