Dash And A/C control lights no longer work

All of a sudden my dash (speedo and tach) and A/C control lights on the knobs no longer work.........all fuses are good......message center light works along with check engine.......etc.........its only the light lights that you can adjust with the dash light control knob.

Possibly a bad dimmer control module in your Light switch. See if you can find another unit at a Junkyard or perhaps a friend with the same vehicle...

Does the Dome override control work and can you turn the Dome lights on with the dimmer switch???

check the knob its self
