If you're talking about the bulb that lights the area with the heat/AC control knobs, they explain it really well here: http://www.volkswagentalk.com/dash-%28heater-switch-lights-%29-replace-t1093.html
If that's not the right light, sorry.
Begin by removing the heater control cover. Take hold of the lightbulb, push in and turn at the same time. The lightbulb will come out and can be replaced in the same manner.
