The light behind the ac/heater controls doesn't come on when you turn light switch on but will when you hit the dash.
SOURCE: How do you replace the light bulbs on the dash heater control
u must pull the entire cluster out to replace the bulbs.

to get to these you need to remove the box above by taking out the rectangular screw cover at the back and take out the one screw. gain access to the edge of the box with a flat tool and gently pull the box clear from its clips. now the 2 retaining screws should be visible that hold the controls in place after removing these you need to pull the controls quite firmly from its clips being careful not to damage the wiring to the back. this multiplug has to be released by pressing a retaing clip on the plug itself. once removed the whole unit needs to be separated into 2 halves being careful of static, by removing the screws on the back.once inside there are grey and white bulbs, white for the illumination and grey for the buttons (heated rear window and a/c etc)

the problem is with the blend door it controls the blend of hot and cold air. there is a small electrical motor that can go bad or they can hang up
you will probally have to take some covers off to find out whats going on

trying to do the same on my 01. ready to change the bulb but can't find it anywhere.
anyhow, here's how you do it:
remove the dash by taking out 2 screws behind the ashtray and 2 above the instrument cluster
begin prying off the dash from the ashtray up, when you reach the heater vents stop. next take a flat head screwdriver and pry off the dash from the left side with the door open. work left to right till you reach the heater vents and it'll come right off. you don't necessarily have to unplug any of the electric connectors if you don't want to, but you;ll have to reach around the dash while working. all you need to do now is remove the heater control unit via the 4 screws around it, then unplug the electric harnesses from the back of it. make sure you remember which goes where. the bulbs are the 3 white (or is it 2 white and 1 grey) circles on the back of the control unit. just turn them with a flathead screwdriver and turn it over and give it a little bump to get 'em to fall out (or grab 'em with a needle nose pliers if necessary). anyhow, that's how it's done, question is, where do ya find the bulbs?
, the middle of the three heater control knobs pulls off. The bulb is right in behind it and lights up the whole panel. I would think a beatle will be the same. give it a try.
