PWR. ANTENNA NOISY WHEN IN USE (REPLACE WITH NEW DESIGN)

SUBJECT: POWER ANTENNA NOISY WHEN EXTENDING OR RETRACTING (REPLACE WITH NEW DESIGN ANTENNA)

MODELS AFFECTED: 1991-1992 DE VILLES, FLEETWOODS, ELDORADOS, SEVILLES, BROUGHAMS, AND ALLANTES

Some 1991-1992 model DeVilles, Fleetwoods, Eldorados, Sevilles, Broughams, and Allantes may experience a condition where the power antenna may create unacceptable noise when extending or retracting. This condition may be worse in colder weather.

To repair the condition replace the antenna with a new part number as shown below. The replacement antenna has a lower viscosity oil in the upper motor bearing and revised plastic shim washer. Antennas built after February 10, 1992 (Julian date 041 92) will use the lower viscosity oil and have an "O" suffix after the part number. Refer to Figure 1 for location of part numbers and production dates.

IMPORTANT: The telescoping portion of the antenna should be periodically cleaned but never lubricated as this will collect dirt and may cause premature failures.

For failures due to a bent mast, the replaceable mast section service kit should be used. A bent mast is usually considered damaged and not covered under the terms of the new vehicle warranty.

Parts are expected to be available on June 15, 1992. In case of limited inventory, parts will be placed on 400 control to waive VIP surcharges. Only verifiable emergency VIP orders will be accepted. SPO will make every effort to obtain parts. However, the part will be shipped premium transportation at dealer's expense, and all other order types will be placed on back order until the 400 control is removed.

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.
