ELECTRO-MECHANICAL INSTRUMENT CLUSTER REPLACEMENT INFO

SUBJECT: ELECTRONIC AND ELECTRO-MECHANICAL INSTRUMENT CLUSTERS REPLACEMENT INFORMATION

MODELS: ALL LIGHT AND MEDIUM DUTY TRUCKS

GMC Truck and AC Delco have formed a joint program designed to help GMC Truck and GM Medium Duty dealers locate exchange instrument clusters. A service called the "Instrument cluster Locator Line" has been established.

For your regular service needs, you should contact the nearest AC Delco Service Center. If they do not have the required cluster, you should then use the Instrument Cluster Locator Line. To do so, call the Locator Line operator at (313) 974-0497 between 7:30 and 4:30 Eastern Standard Time. The following information is required:

- the name of the AC Delco Service Center previously contacted

- the part number of the unit needed

- your dealer name, address and telephone number

- the make and body style of the vehicle being repaired.

The operator will then locate another AC Delco Service Center which has the required cluster and call you back that same day to let you know where the part can be found.

You can then order the part directly from that Service Center. The part will be shipped within 24 hours and you will receive it within 48 hours. Please note that the Instrument Cluster Locator Line Program should only be used if the electronic or electro-mechanical cluster is not available from your local AC Delco Service Center.

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.
