Heater problems??

[Saw76]

Hey Guys and girls, I have a strange problem with my 2000 Boxster. The climate control is working erratically. When my friend plugged it into a durametric computer it came back with four errors. (hot cold flap fail,blower fail, and two others i don't recall. We checked fuses all of them were good.So basically I get heat all the time not much. Then if I manually turn off the ac button I get heat out of everywhere. Then after a while some doors move and I get full heat. Anyone hear of this and know of a relay somewhere or something that would cause all 4 fails like that? None of the doors work and then they start working sometimes. The car has been sitting for two years.
Thanks
Seth
