CD VOLUME DROPS W/WIPER USE SEND CD PLAYER TO AC-DELCO

SUBJECT: COMPACT DISC AUDIO VOLUME DROPS MOMENTARILY WHEN USING WIND-SHIELD WIPERS - EXCHANGE OR REPAIR CD PLAYER

MODELS/YEARS: 1991-92 TORONADO

Some 1991-92 Toronados and Trofeos may experience a condition where the CD audio volume will momentarily drop when the windshield wipers sweep or park. The condition may occur on vehicles built with the U1H audio system (integral radio/equalizer/cassette and remote CD) and without the color CRT (U68).

This condition may be caused by transient electrical signals entering the audio system causing a momentary drop in volume.

To repair the condition, send the remote CD player to an authorized AC-Delco repair shop and request that bulletin RD91TBA14 be performed. There is no approved on-vehicle repair.

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.
