INFORMATION ON INSTRUMENT CLUSTER ASSEMBLY REPLACEMENT

SUBJECT: Service Information on Instrument Cluster Assembly Replacement

MODELS AFFECTED: 1991-1994 Saturns

PURPOSE: When servicing an instrument cluster assembly, the following guidelines must be followed in order to ensure an efficient and cost effective repair.

SERVICE PROCEDURES

Removal and installation procedures can be found in the "Instrument Panel and Console" section of the "Body/Collision Repair Service Manual."

IMPORTANT: Failure to remove power when removing or installing an instrument cluster assembly may cause the fusible link on the back of the instrument cluster assembly to open.

Diagnostic procedures can be found in the "Power Distribution" section of the "Electrical Service Manual."

Instrument Cluster Assembly Technical Tips

Following is a list of normal performance characteristics of the Saturn instrument cluster assembly that have prompted unnecessary instrument cluster assembly replacements:

1. Odometer steps, instead of a smooth continuous movement.

2. Odometer makes a slight ticking noise.

3. Main odometer and the trip odometer may not synchronize when they turn over. The roll over point of the trip odometer versus the main odometer is determined by when the reset button is pushed in, during the main odometer cycle.

4. Speedometer may not start to move until the vehicle has reached 13 km/h (8 mph).

5. Perception of a large gap between the white metal wheel and the first black wheel on the trip odometer is similar on all instrument cluster assemblies.

6. Fuel gauges on 1991 and 1992 vehicles retum to zero when the ignition is turned Off. On 1993 and 1994 vehicles, fuel gauges will stay within five angular degrees (about 2.5 tick marks) of actual level when the ignition is turned Off.

SERVICEABLE COMPONENTS

The instrument cluster assembly is serviced only by replacement. The only authorized retailer repair is bulb replacement. The following bulbs are available through Saturn Service Parts:

Part Number Description ----------- ----------- 21020635 I/P Cluster Telltale Lamp 21020634 I/P Cluster Back Light

PART NUMBER IDENTIFICATION

To identify the correct part number for the replacement instrument cluster assembly, obtain the full vehicle identification number (VIN) and record VIN positions four, five, six and ten. Match these VIN position numbers to the "Instrument Cluster Assembly-Part Number Reference Chart" shown on the last page of this bulletin.

MILEAGE DETERMINATION

The replacement instrument cluster assembly mileage must match exactly with the mileage of the instrument cluster assembly being replaced. Since the instrument cluster assembly cannot be repaired, the mileage must be stated when ordering the replacement part. Sublet repairs to speedometer shops for mileage changes are not authorized.

In order to ensure an exact mileage match, the vehicle must not be driven after the replacement part is ordered. If the customer requires alternate transportation, obtain prior approval from your area team leader at the Saturn Assistance Center. If prior approval is obtained, submit a claim for reimbursement from the Saturn Dealer Systems as follows:

Labor Case Operation Type Description Code ---- ----------- --------- GW Instrument Cluster R & R N4180

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.
