You will need a multimeter or test lamp. First, turn on the light switch and check for voltage at the instrument lamp fuse. Either end will do if you know the fuse is good. If you have voltage, your problem is between the fuse panel and the cluster or within the cluster itself.

If no voltage, connect a jumper between the instrument lamp fuse and any fuse that is hot all the time, like brake and dome or cigarette lighter. Do the lights work now? If yes, everything downstream from the fuse panel to the cluster is good and your problem is in the switch or between the switch and the fuse panel. If still no lights, your problem is between the fuse panel and the cluster or within the cluster.

If the switch is suspect, unplug the switch connector and get it out to where you can work with it. Connect a jumper between the red and green wires. If the lights work now, the switch is probably bad. If they still don't work, your problem is between the switch and the fuse panel.
