I suppose I'd make sure your compressor clutch was connected to the head unit of your AC? I'm not certain about the 944, but one way to force the clutch to engage in some cars is to turn on the fan.
You should have a signal from the A/C head unit (the one the interior temperature gauge is connected to) that engages the compressor.
The other problem may be you have air in the system, which doesn't compress and expand as well as freon so it just doesn't work as a coolant.

I experienced the same symptoms as described in this thread when the climate control head unit failed. This temperature control unit can fail over time and is a common problem. See if someone near you has one to borrow and test in your car. Not difficult to swap out.
