It looks like there might be two lights behind the three knobs for the vent, heat and temperature knobs. The knob on the right, the one where you choose how cold or warm you want the air to blow, is not lit up at night. The other two knobs are lit up fine. Is there a way to fix this?
So googling this, I found one other person with the same problem. He was told he'd have to replace the whole "A/C control head assembly," but I can't find that part anywhere online. Guess I have to ask a dealer
It doesn't necessarily involve replacing the whole assembly. I did when I had to replace the bulbs in mine, but that was because I broke it trying to get it out.
The bulbs are replaceable on their own, but it is not generally a fun process. Here is a pretty nice writeup:
I'm having the same annoyance. It worked fine 2 days ago, last night was a no show. Looks strange with just 2 working, and the third one dark. Seems there would be an easier way to fix this than removing the radio and all the surrounding stuff just to reseat or replace a small bulb.
