Instrument lites are on a small amp fuse 3 or 5 amps. The lite switch may supply the power to the instument lites. to the fuse box first,then to the instrument panel. LOOK for the color code of the wire to the fuse panel and to the instrument cluster,check for power,in this wiring.Check bulbs and the grounding wire for the panel.Check all the plug ins.
