I replaced the bulb in the AC Control Panel today..
Very Very easy.. I needed to get the Radio keys to remove the AC Control Panel. I made my own out of a plastic hotel key. I cut the thin plastic with a pair of scissors I cut them 3/8in. wide and made a taper at the end. I positioned the taper to face inward toward each other. I slide them in, and used the rest of the plastic card to pry the unit out... The bulb is in the center in the bottom. It came right out with a twist..
