Some 1985-1990 Fleetwoods and 1988-1991 Fleetwood Sixty Specials equipped with memory seats may experience a 1/2 to 2 inch loss of horizontal position on recall. This condition may be caused by grease migrating into the horizontal drive motor from the outboard horizontal drive cable. This grease can coat the motor armature contacts causing the memory module to see an incorrect position signal. To repair this condition use the following procedure:
1 . Remove seat bolts at floor pan and disconnect electrical connections.
2. Tilt seat backward to gain access to seat adjuster.
3. Remove the outboard horizontal drive cable and motor assembly and discard. Refer to Figure 1.
4. Replace the outboard horizontal drive cable with P/N 20515599. Do not grease this cable. Replace motor assembly with P/N 20560003.
5. Replace seat bolts. Tighten to 28 N.m (21 lbs. ft.).
For warranty purposes use Labor Operation T5199 at .6 hour.
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.
