climate control knobs wont light up!!! help

hello everyone. i have a 94 camry le and the weird thing is that none of the knobs used to adjust the fan speed or temperature will light up at all.
the only one that lights up is the AC green button when pressed in. everything else works, like my instrument panel, etc. i checked fuses under hood and by my knee, but maybe im missing something. i highly doubt theyre all blown out seeing how they have to be on the same circuit. thanks in advance for any help!!! i roughly  checked the harnesses in back too

Mine's doing the same thing. Intermittment problem. I believe the only "fix" is to replace the entire HVAC panel with another one.

Try your local import salvage yard or Ebay. I've seen them under $20.
