This could be a problem with Ground #302, which is located below the center console. Both the instrument cluster and the Integrated Control Module are connected to this ground. I have included a Ground Distribution Wiring Diagram of your vehicle showing this in the diagrams down below. Check this ground and make sure that it is clean, tight, corrosion free, and making good metal to metal contact. Using a toothed washer on the bottom of the ring connectors is advisable, as it unsure good metal to metal contact in case paint is in the way. Please get back to us with what you are able to find out.
