RADIO BACKGROUND HASH ON FM BAND INSTALL RFI SUPPRESSOR

1988-89 REGALS

Some 1988-89 Regals may exhibit a condition perceived as weak FM radio reception. This condition may be caused by fuel pump induced noise which results in background hash on the FM band.

Vehicles exhibiting this condition may be repaired by installing P/N 25027405, RFI Suppressor Harness Unit. Instructions and applicable parts required for installation are contained in the service unit.

Parts are expected to be available on July 21, 1989. Until then normal part orders will not be accepted by GMSPO. Only verifiable emergency VIP orders will be accepted. SPO will make every effort to obtain parts. All parts will be placed on 400 control to waive VIP surcharges. However, the part will be shipped premium transportation at dealer's expense. All other order types will be canceled as incorrectly ordered while the 400 control is in place.

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.
