Buick is pleased to announce an Exchange/Repair Program for instrument clusters and cathode ray tube 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 2nd day UPS, within 24 hours of the request. The memo billings are cancelled when inoperative instrument
clusters are received by the service center from which exchange 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 problems perceived by the observer to be in the
instrument cluster are actually problems with remote sensors and connectors. Proper diagnostics will identify the source of the problem and avoid
unnecessary removal and shipping of functional assemblies to service centers.
2.
When diagnostics are complete and the condition is determined to be in the unit, determine whether the unit is built by (DE) Delco Corporation or
American Yazaki. (The Park Avenue and LeSabre Quartz Analog Instrument Cluster, and some of the Skylark clusters are made by American
Yazaki.) The manufacturer of the cluster can be determined by matching the unit to the cluster illustrations on the attached pages. If the cluster is a
DE Corporation Unit, call any one of the Service Centers listed on the attached pages. If the cluster is an American Yazaki unit, only call one of
the service centers designated with an (*) asterisk. If the service center called does not have the exchange unit in stock, call other service centers
until an exchange unit is located. If the odometer is part of the exchange unit, tell the service center the mileage to which it should be set. Centers
designated by an asterisk repair both Delco (DE) and American Yazaki units.
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 instrument cluster. Hands must be free
of dirt and grease. Avoid touching electronic components, as electro-static discharge can degrade performance or cause failure.
4.
Remove the inoperative instrument cluster and replace it with the exchange unit.
5.
Include a description of the instrument cluster problem 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.
