The instrument cluster contains all of the important gauges on your Silverado truck like the speedometer, odometer and the fuel gauge. If any problems arise within the cluster itself, like a needle going awry, you will generally need to replace the entire cluster. It is possible, however, to rebuild the cluster in small ways by replacing components like the lights and their bulb holders. The cluster is mounted within the instrument panel above the steering column.
Disconnect the truck's battery, loosening and detaching the black cable clamp with your wrench.
Pry the instrument cluster bezel off of the dashboard. Older models may require a trim stick, but you should be able to grasp and pull for 1999 and later models.
Lower the steering column using its tilt lever.
Remove the screws fastening the instrument cluster and pull this cluster from the instrument panel. Disconnect all the electrical connectors in the back end of the cluster.
Rotate each bulb holder counterclockwise and pull them out of the instrument cluster's back end.
Pull the light bulbs out of the bulb holders.
Insert new light bulbs into the bulb holders, using a rag or gloves to hold them so as not to get oils on the bulb glass.
Insert each bulb holder into the replacement instrument cluster and turn them clockwise to lock them in place.
Insert the cluster into the instrument panel, connecting its electrical connectors, and fasten it in place with the screws.
Raise the steering column back into place and reconnect the instrument cluster bezel on its clips.
Reconnect the negative battery cable.
