I'm going to do the same thing to replace the bulbs this weekend. The instruction I found just mention to remove the radio and unclip the control from the frame through radio hole. Keyword for search is "climate control".
What kind of bulbs are you getting to replace? Can I find replacement bulb at Pepboy or Kragen (I'm in California)?

I didn't want to break anything. Do i need to take some molding and panels off ?
