Hi man, I did that fix today, there are actually two light bulbs that illuminate the whole AC control panel. Getting to them is actually pretty easy, but you have to dismount the A/C controls, because the lights are on the back of the panel:
They should look like this:
The blue color is actually a little rubber cover, be careful not to tear it apart or you will end up having a yellowish color on your AC controls, that happened to me at first, so changed the bulbs for white 12v LEDs and now it is looking good:
I hope this helps, man
