I own a black 2001 SL500. One pet peeve however. There are no lights on the temperature panel buttons. I end up having to hit the internal light near rear view window to change settings at night.
Is there a fuse problem or do they simply not light up.

There is no dedicated fuse for the controller illumination. Assuming other components light up, then the problem is likely a bad bulb in the controller.
On the older-style controller, the bulb is easily accessible, and I would assume this is true of the newer-style like you have as well. All you have to do is remove the controller. You do this by inserting a pair of DIN radio removal tools into the openings on the face of the unit and pulling out. These tools are all over eBay for about $10 if you need them.
