try disconnecting your battery for 10 minutes and then hooking it back up. its a start.

Remove the related fuse(s) and drive it for 10 minutes. Put them back in and then see what happens. Just a guess.

you may need a new heater control unit for the console. you can sometimes find them for sale on the forum.

Not sure if the C6 is different than the C5 in this matter.
I had this issue when I owned my C5 sometime back and it turned out to be a vacuum issue, a small hose was disconnected in the back of the intake manifold.
Have you had any work done in that area of the engine ?
Honestly though not sure that the controller is vacuum controlled in a C6 like it is in a C5 but throwing some ideas out there...
