Customer comments that either cassette tapes cannot be ejected unless the radio or ignition is turned off or that the tape deck will not accept a tape cassette may be caused by an open or shorted tape eject button. This condition may affect some 1984 Eldorados and Sevilles equipped with a Bose radio or 1985 (FWD) Devilles and Fleetwoods equipped with any cassette tape deck.
Verify the customer comment with a known good tape because the normal operation of the tape deck will eject or not accept a tape cassette if the tape cassette is damaged (i.e., binds or jams). The unit should not be removed if the customer has the condition only with a specific tape cassette. Only after the condition is verified should the unit should be removed and sent to an authorized AC-Delco Service Center for repair. The specific condition should be described on the AC-Delco Repair Claim Form as "tape eject button inoperative."
For warranty purposes, use labor Operation No. T6120 at .4 hour for R&R receiver and cassette tape operation test.
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.
