What, no one going to mention being blasted with cold air from the top vents in Winter just because its sunny!
Actually, although I opened the door for the elaborations, I've never really found it to querky in either the retro-fit on a 2002 Zetec or my current (from new) Ghia.

If I want to over-ride it, there are plenty of buttons to play with.
The thing that would be really nice though, but might cause even more confusion, would be a cabin temperature display option.
