I've got this Heat/AC control (pictured) that works fine, but definitely needs some cosmetic help. At the very least, the lens needs polishing and the two bottom knobs need re-chroming. I spent some time messing with it today, and I haven't figured out how to get the lens and knobs off it without possibly destroying something.

I also did some checking for a NOS unit (hey, you never know) and came up empty-handed. I also did a search here and came up only with threads about heater hoses, heater boxes... you get the idea.

Any advice is appreciated from someone who has done this.
