INSTRUMENT CLUSTER EXCHANGE REPAIR PROGRAM

VEHICLES AFFECTED: - 1988-89 EXCHANGE UNIT NUMBERS - PASSENGER VEHICLES AND ALL TRUCKS

The Instrument Cluster Exchange/Repair Program for digital and quartz electric speedometers and Driver Information Centre (D.I.C. modules has been expanded to include the 1988-89 models. This program provides repaired component assemblies in exchange for inoperative ones.

When a replacement assembly is required for a 1988-89 model, the following chart should be referred to. Please pay special attention to those clusters where only the speedometer assembly is exchangeable.

The remaining portions of the cluster such as fuel gauge, temperature gauge, etc., are replaceable through the normal parts channels.

NOTE THAT INSTRUMENT CLUSTERS ABOVE HAVE TEMPERATURE TELLTALES, BUT NOT LOW COOLANT TELLTALES. ALSO, GAUGES ARE OUTLINED. (WITH TAN/WHT WIRE TO ALTERNATOR).

1st Type Clusters contain a 470 ohm resistor which provides a reduced voltage through a brown wire to the alternator "L" terminal for field excitation, if the warning light indicator bulb burns out.

2nd Type Clusters do not contain a 470 ohm resistor. There is no voltage from the cluster to the brown wire going to the "L" terminal of the alternator, if the warning light indicator bulb burns out. The alternator field excitation is achieved by supplying 12 volts from the #4 fuse through a Tan/Wht wire to the "I" terminal of the alternator. The alternator "I" terminal is internally connected to the "L" terminal through a 470 ohm resistor.

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.
