no light in the instrument cluster. on 2002 Ford Explorer

When light switch is turned on no light will come on.

Check your fuses, then remove the light switch, and see if there is power at the switch. If there is power at the switch, see if you get a wire that increases in voltage as you turn up the switch. My guess is, there will not be, but test before you replace because it could be a wiring/connector issue.
