CASSETTE TAPE WILL NOT EJECT RETURN CTRL. HEAD TO AC-DELCO

SUBJECT: CASSETTE TAPE WILL NOT EJECT

MODELS AFFECTED: 1992 BROUGHAMS

Some 1992 Broughams built before VIN breakpoint 707550 may experience a condition where the cassette tape will cycle up and down but not eject when the "eject" button is pushed. The condition may occur on vehicles built with either the standard or optional radio system and is sensitive to the dimensions of the cassette tape cartridge. Some tapes will eject normally while others may repeatedly fail.

This condition may be caused by an interference between the tape door and internal circuit boards on vehicles with a certain tape door design. Refer to Figure 1. Early 1992 radios have a tape with a larger, symmetrical "bump" feature where the height and width dimensions are nearly equal. The revised door "bump" has a teardrop shape with less overall protrusion and is relatively narrow, similar to the design used in the 1991 model.

To repair the condition return the radio control head to an authorized AC-Delco repair shop with a statement of the problem, and request that bulletin RD92TBA03 be performed to change the tape door. Or, request a pre-exchange control head using the procedure described in DSIB 92-I-1. Request the repair sh verify that AC-Delco bulletin RD92TBA03 has been performed on the pre-exchange control head.

For warranty purposes use Labor Operation R0765, Radio Control Assembly R&R, at .2 hour.

NOTE: AC-Delco Service Centers listed in DSIB 92-I-1 will have inventory to do pre-exchanges. If a listed center does not have model 16153946 (cassette) or 16149006 (cassette and CD) radio control head in stock, contact the AC-Delco locator service as described on page 3 of DSIB 92-I-1.

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.
