# EXCHANGE - REPAIR FOR INSTRUMENT CLUSTERS

#### MODELS AFFECTED: 1989 CENTURY, ELECTRA/PARK AVENUE, LESABRE, REGAL, REATTA AND RIVIERA

Buick is pleased to announce an Exchange/Repair Program for instrument clusters and cathode ray tube (GCC Monitor) units used on the above listed models. This program provides repaired instrument clusters in exchange for inoperative ones at a cost substantially below new replacement parts.

Instrument clusters are serviced by the exchange units listed in this bulletin. See pages with illustrations for part numbers and applications.

Exchange units are obtained by telephoning one of the twenty nine authorized AC Delco Service Centers listed on the last three (3) pages of this bulletin. They are shipped with memo billings, via next day UPS, within 24 hours of the request. The memo billings are cancelled when the inoperative instrument clusters are received by the service center from which units were obtained.

Please adhere to the following procedure when a vehicle requires dealer service for an inoperative instrument cluster:

1. Follow the diagnostics procedure in the Service Manual precisely and completely. Many conditions perceived by the observer to be in the instrument cluster are actually conditions with remote sensors and connectors. Proper diagnostics will identify the source of the condition and avoid unnecessary removal and shipping of functional assemblies to service centers.

2. When diagnostics are complete and the condition is determined to be the instrument cluster, determine which exchange is required by matching the unit to the cluster illustrations on the attached pages. If the odometer is part of the exchange unit, tell the service center the mileage to which the cluster should be set.

3. Upon receiving the exchange unit from the service center, take it into the vehicle still packed in the reusable shipping container. The container protects it from damage due to static electricity. Use care in handling the exchange unit and the inoperative cluster. Hands must be free of dirt and grease. Avoid touching electronic components, as electrostatic discharge can degrade performance or cause fallure.

4. Remove the inoperative instrument cluster and replace it with the exchange unit.

5. Include a description of the instrument cluster condition in the "Nature of Problem" area of the ACD-1078 form. Pack the inoperative instrument cluster in the reusable shipping container, together with five (5) copies of the completed ACD-1078 warranty form.

6. Enclosed in the reusable container is an addressed shipping label. Attach this label to the outside of the box and ship immediately to the service center from which you obtained the exchange unit. The dealer copy of the ACD-1078 warranty form will be returned and the memo billing cancelled upon receipt of the inoperative instrument cluster at the service center.

7. Failure to return the inoperative instrument cluster in the special reusable container, can result in a container replacement fee. Failure to return the ACD-1078 warranty form or the inoperative instrument cluster to the service center within 30 days of the date the exchange unit was shipped, can result in a repair fee or an instrument cluster replacement fee.

The success of the instrument cluster Exchange/Repair Program is dependent upon prompt return of the inoperative instrument cluster to the service center. Your cooperation is essential to maintaining sufficient quantities of exchange stock.

Please adhere to the following procedure when a vehicle requires dealer service:

2. If the cluster is determined to be inoperative when diagnostics are complete, call Nippondenso and request an exchange cluster.

3. After the exchange cluster is received, remove the inoperative cluster from the vehicle.

4. Install the exchange cluster in the vehicle. Handle the cluster carefully, making sure hands are free of dirt and grease.

5. Complete the Nippondenso Repair Order received with the exchange cluster and be sure to include a description of the cluster malfunction.

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.
