Instrument Cluster HELP

The steering wheel illumination, radio light dimmer, 4wd mode switch illumination, climate control and instrument cluster backlight are all on the same circuit. Since you lost the climate control backlight, it's probably not the ground side.
The hot side is all wired up to the pulse width dimmer module which gets its power from the headlight switch. It's very likely either you aren't getting 12v to the dimmer module from the headlight switch, the module is bad, or its output is shorted to ground somewhere
