I have a 2000 1.8T beetle. The AC has been cutting out. It switches between ice cold and warm musty air. So far I have replaced the cooling fan switch, cooling fan control module, coolant temp sensor, AC dryer, AC compressor, H block, and the thermal switch. I did the fan module and switch myself and after that didn't help I gave in and took it to a shop which resulted in a bill of nearly $1000 and of course no resolution. The shop seems to be a bit stuck trying to figure it out at the moment. I can jumper the fans and make them both run at both speeds, however I usually find the large fan not spinning when the AC cuts out. Any idea's as to what might be the issue?
