OPERATION OF ALLANTE TURNING SIGNAL DISPLAY

1990 Allante digital and analog instrument panel clusters will display a two-ended arrow which blinks when either the right or left turn signal is actuated. This condition is the design intention for 1990 models. There will be no repair for this condition. The Owner's Manual description of individual left and right turn signal display operation is incorrect.

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.
