lighting problems in temperature control box

I am wondering if the lights in the temperature control box are replaceable, I have the adjustable heating controls in my car, and now have both burned out right and left temperature control knob lights out, the lights that glow and make the red and blue arc illuminate everything else is fine, I was trying to look inside the box and see what was in there, but I thought I would ask the question first before I go and explore to much. thanks..

There is a guy on clubgp who repairs them for pretty cheap.

His username is grandprixfamily, shoot him a PM and ask.
