Sortly after buying my 2002 NB GLS TDI last month I noticed that the HVAC controls under the radio do not light up. They normally do, don't they? 
Lnzbug, did you need pliers to pull out the fan control knob? My headlight switch came out easily when I replaced it with a Euroswitch. The fan control knob doesn't seem to want to come out that easily.Yes they do. You need to change the bulb that is located behind the fan control. Turn it to the second speed and pull the knob straight out.Cover the knob with a piece of rubber to protect it. (I used a jar opener gripper)
That's why I used one of those jar opener gripper things. It worked like a charm, no scratches either.98silverbeetle said:on my '98 it took quite a bit of effort, it was really annoying because you are trying to keep it covered so you don't scratch it, yet you want the thing to come off.
Here's what I used, a #2721 bulb from Advance Auto. jasonwinters3 bought his from Advance:Lnzbug, I am so glad you posted this fix as I am having the same issue! I have a question though. Can you get the bulb at Autozone or Advanced Auto, and if so, any idea what the number is? The dealer is out of the way and the others quite close.
