RADIO WILL NOT TUNE PAST 104FM (MAYBE SHORT TO GROUND)

MODELS AFFECTED: 1987-1988 ALLANTES

Some 1987-1988 Allante radios may not tune past 104 FM manually or when using seek/scan. This may be due to a short to ground on the radio export strap, circuit 945, which will keep the radio in the European mode. If the radio is in European mode, "50 mHz" will be indicated in the top right corner of the radio display.

If a vehicle exhibits this condition back out circuit 945, purple wire, from cavity 1 in the radio control head connector. The radio should return to the standard American mode and allow tuning past 104 FM. Leave the wire out of the connector and tape it to the harness to prevent a rattle in the dash.

For warranty purposes use Labor Operation N6360 at .5 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.
