Intermittent HVAC control lights on 93 Corolla

I have a 93 Corolla and for the last year or two the light behind the center console HVAC area (heating ventilation and AC controls) has been intermittent. Usually when I start driving at night this area is not illuminated, but will often become illumintaed at some point later and stay on for the remainder of the drive. All the other lights (dash, etc) work 100% of the time.

Any ideas?

Got the same problem on the wife’s Celica. The dealer fixed it once, lasted a few months. We just live with it. I would guess that if you disassembled everything an carefully cleaned all the connections using a proper contact cleaner, that would do it and likely cost as much as the car is worth.
