The first thing to check is the connector on the back of the instrument cluster. A female connector is mounted to the instrument panel, and a male connector is mounted to the back of the instrument cluster. When the cluster is installed, the cluster retaining screws are the only means of keeping the two connectors tightly together. If the screws that hold the cluster in place become loose, no tellin' what instruments will go crazy!
