A surprise for me today, on the way to work. The lights that make the active button brighter than the rest, on the a/c control unit, came to life! I thought the bulbs were out, as this has never worked since I owned the car! Now I am worried I have a different problem altogether....

Any input on this? I have recently repaired the relay controlling the driver's side activation of the interior light, maybe this has something to do with it? I do not have the schematics here at work to check yet, just looking for some advice.
Thanks!

It is surprising how often things like this occur. The probability of all the bulbs being burned out at the same time is just so low. Probably a dirty connector or intermittent open. Don't worry though, it will probably come back.

No matter what you fix, there will always be something else to fix..
"Warranty" is just another way of postponing the inevitable.
