Wow, people using A/C? I am still using my heat! Heh!!! Though, I can't use A/C in my VX with my S/C cause it causes too much overheat anyways.

I will agree it doesn't sound like the unit as much as it does the electronics/wiring. And sadly, that is where I draw the "dumb" straw. I heard of a similar problem with a buddy who has a VW. His auto temp control had a mind of it's own. A visit to a VW dealer revealed and solved his issue. I never heard what the issue was though. Pesky dashboard poltergeists.
