Hi, I can give you wiring diagrams for the instrument cluster illumination, but, you have to track the circuits. Did you check applicable fuses? You also need to check for voltage on the fuse circuit. Even if the fuse is good, if no voltage on the circuit, the circuit is dead. I can't tell you exactly what is causing the problem with inst lamps, I can help track the circuit. You see the int lamp fuse, the circuit goes hot when you turn on the headlamp switch, check for voltage on the fuse circuit. The gray wire from dimmer module carries voltage for instrument lamps. The dimmer control for interior lamps may be turned all the way down?
