Source: Chevrolet Service Bulletin
Bulletin Number: 91-115-8B - (01/15/1991)

The 1991 Corvette is equipped with a Delayed Accessory Bus (DAB) which allows operation of the power windows and audio system for 15 minutes after the ignition is turned off. This owner convenience feature is cancelled when the driver’s door is opened.

No attempt should be made to override this system.

Operation of the DAB is covered in the 1991 Corvette Owner’s Manual and Service Manual.

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.
