Question lights on ac/heater temp blower panel

I've had my 05 TJ for a little over a year now - when I bought it the light on the fan control intermittently went in and out - the out for good - then my temp knob light - now none (on that control panel)

I pulled the panel but all bulbs are still functional - doubting the little lights wouldn't have a fuse of their own - I checked anyways - and all fuses functional - when I had the panel out I checked all connections to ensure proper seating

all the controls function - just cant see them in the dark - my only guess now is maybe the actual circuit board is malfunctioning - which if that's the case I'm sure its not worth replacing just for the lights -


tl:dr - ac control panels wont light up anymore - tried everything I can think of to make work - nada

I think the bulbs are dead. How do you know the bulbs are functional?

Yep, do an actual voltage check. Test light needed or a voltmeter.
See if you have power and ground at the circuit board, where the bulbs connect.
If so, then check the sockets and bulbs.

If not, start with a wiring diagram and find out where you are loosing the power/ground.

But, at least from your description it sounds like you have bulbs that one after another gave up.
