The illumination on my heater/ac panel appeared really dim, so I attempted to take it out to check the light bulb; when I tried to remove the bulb holder from the socket at the back of the panel, the holder broke and part of the sides seem to be stuck inside the socket (the light's never been changed since I bought the car in '92) Now, I don't have any illumination at all at the panel; is there a way to replace just the bulb holder and socket or do I need to get a whole new panel? If I do have to replace the panel, how hard is it to do?

Thanks!
