Replaced my FSU with a new unit from autohaus, and my ac is still acting up. It turns on when it wants, or sometimes it will appear off on the display, but still blows out some cold air. I could hear some buzzing under the driver side of the dash but not sure where else to go with this. Could it be the climate control unit itself?? I don't think it is.

Actually, those symptoms sound exactly like a bad Climate Control module.

Is that the whole unit where the display is?? Damn I just replaced all those buttons,.. had I known this unit was gonna crap out,.. I would've replaced the whole thing.

Yep...

any update on this?
