climate control problem, please help!

[jimbo1]

I have recently purchased A GT TDI with Climatronic.  The problem with it is that it seems to be adjusting the fan speed and which vents are open continuously.  I know that climate adjusts as and when necessary but mine is doing it constantly.  Whether I'm at standstill or driving it still does it.  It sounds like someone is turning the fan speed up and down and opening and closing the vents constantly.  Sometimes the windows just steam up mid journey like the re-circulate button has been pressed but I've not touched a thing!  Guess I'm kind of hoping the climatronic unit can be reset or get a replacement off ebay I guess.  PLEASE HELP

The fan flap motors fail for a passtime:

Get it on vag com or a fault code reader to see what fault codes pop up

Thanks for advice.  It's not the same problem in that my temperature changes up and down normally it's just the fan speed and direction that is going funny.  Could it still be the positioning motor for a temprature flap causing it though?
