# QUARTZ AND DIGITAL INSTRUMENT CLUSTER REPAIR INFORMATION

Applies to: 1985 FWD Deville and Fleetwood 1981-1985 Eldorado or Seville with Digital Instrument Cluster

The 1985 FWD Deville and Fleetwood standard quartz and optional digital speedometer are availabe as an exchange unit from authorized AC-Delco service centers listed in this bulletin. The quartz replacement cluster requires the odometer to be transfered by the dealer from the inoperative cluster to the replacement cluster. On 1985 FWD Devilles and Fleetwoods with digital speedometers it is necessary to remove the odometer chip from the inoperative cluster and transfer it to the replacement cluster when service is required. Reference Serviceman Bulletin T-84-105, 31 group 8 for both procedures. Dealers should continue to handle repairs of 1981-85 Eldorado and Seville digital cluster service as in the past through any of the AC-Delco Servic Centers in this bulletin.

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.
