Has anyone ever replaced the entire Climate Control Module? I have the usual broken buttons (Max and Fan) but also the Recirculation and Foot button lights are burnt out. So instead of just replacing the buttons I figured I might as well replace the entire unit.

How difficult is this?

Also, when I inquire about the part, I'm always asked if I have rear A/C. How can I tell? My center console has the fan and temp dials for the rear, but does this qualify as rear A/C?

I have a 2001 3.0i.

Thanks.
