DIGITAL AND ELECTROMECHANICAL INSTRUMENT CLUSTERS
MODELS: 1989 C/K, S/T, AND M VANS 1990 C/K, R/V, S/T, G AND M VANS
THIS BULLETIN CANCELS AND REPLACES GMC TRUCK SERVICE BULLETIN 89-T-17, CORPORATE NUMBER 868305R TO ADD THE 1990 MODELS, AND TO UPDATE THE LIST OF SERVICE CENTERS. ALL COPIES OF 89-T-17 SHOULD BE DISCARDED.
The purpose of this bulletin is to announce an Exchange/Repair Program for instrument clusters used on the above listed models. This program provides remanufactured instrument clusters in exchange for inoperative clusters.
IMPORTANT: The 1989 VAN and 1990 R/V, G and M van clusters have nonreplaceable gages and MUST be serviced using the "Instrument Cluster Procedure" listed below.
The gages in the 1989-90 C/K and S/T clusters are individually serviceable, and available through GMSPO or service centers through cluster exchange. The dealer should use good business judgement when determining which course of repair to follow on these models.
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 any of the twenty-eight authorized AC-Delco Service Centers listed on the last three (3) pages of this bulletin. They are shipped with memo billings within 24 hours of the request via next day UPS. The memo billings are cancelled when the inoperative instrument clusters are received by the service center from which units were obtained. If a unit is on back order at one of the service centers, it may be ordered from any of the other service centers.
Please adhere to the following procedure when a vehicle requires exchange service for an inoperative instrument cluster:
NOTICE: If odometer is reset, refer to applicable "Policies And Procedures Manual," Section 1.10.3 Odometer Servicing. Odometer Servicing labels can be obtained from local office supply companies.
INSTRUMENT CLUSTER PROCEDURE:
1. Follow the diagnostics procedure in the appropriate 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 problem and avoid unnecessary removal and shipping of functional assemblies to service centers.
2. When diagnostics are complete and the condition is determined to require an exchange cluster, determine which exchange cluster 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 what mileage the cluster should be set at.
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 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 of 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. INSTRUMENT AND DISPLAY SERVICE CENTERS

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.
