Analog Instrument Cluster

CAUTION: The instrument cluster requires special handling to avoid damaging internal components. The cluster MUST be kept FACE UP or in the in-vehicle position. Leaving the cluster face down may result in a loss of dampening fluid used in the gauges. The lost fluid could stain the cluster face or result in excessive pointer waver.

NOTE: Federal law requires that the odometer in any replacement speedometer must register the same mileage as that registered in the removed speedometer.

The instrument clusters are serviced as a complete assembly. The only instrument cluster components that are serviceable at the dealership level are:
a. Cluster Lens (10B885).
b. Illumination Bulbs (13B765).
c. Lens Attaching Screws (804988).

If the diagnostic procedures result in a determination that any other instrument cluster component is faulty, the complete instrument cluster must be replaced.

The service cluster received will be pre-programmed with the vehicle mileage (eliminating the need for circled S odometers) and the Programmable Speedometer/Odometer Module (PSOM) speed signal conversion constant.
