The gauges can be replaced individually on some models, but others require replacement of the entire gauge cluster assembly. The instrument cluster contains many components; inside the cluster are modules, printed circuit boards, fuses, and some also contain small microprocessor computers for the clock and driver information center. Diagnosis of this system is complex, and the cost of parts is high; since most parts are special order only, trial and error replacement is just not practical. It is advised to diagnose the failed component before replacement.

On models where the gauges can be replaced, simply remove the instrument cluster as outlined in this section, and remove the cluster cover. Remove the retaining devices (some use bolts, some are held in by tabs, etc.) and remove the gauge from the cluster. To install, reverse this procedure.

On models where the cluster must be replaced, remove the instrument cluster as outlined previously in this section. Remove the printed circuit board and any components necessary to remove the board, then remove the cluster cover. Unfasten the instrument cluster retainers and remove the gauge cluster assembly.

When replacing a speedometer or odometer assembly, or the instrument cluster, federal law requires the odometer reading of the replacement unit to be set to register the same mileage as the prior odometer. If the mileage cannot be set, the law requires that the replacement be set at zero and a proper label be installed on the drivers door frame to show the previous odometer reading and date of replacement.
