When AC is turned on, the compressor should be working. If the clutch is not turning with the engine, you need to test if power is being supplied to the clutch coil.
If no power present, it could be due to lack of freon or faulty power sources which can be blown fuse or faulty relay.
To test compressor, apply power to the coil wires and you should hear a click.
To test freon you need a pressure gauge, you can try asking at your local Autozone outlet.
