First few guesses would be either a worn out but non-seized compressor, or a bad expansion valve. The system should be hooked up to a manifold gauge set and the high and low pressures monitored. Other possiblilty would be that you are only seeing the pulley turn and the compressor clutch isn't actually engaging the pressure, although you seem to think you see some flow or movement in the receiver-drier window, whch would indicate the compressor is in fact doing "something" although a worn compressor is still a possibility.
