Hello,
The compressor will be on the belt system on the front of the motor. When you look at it all the other pulleys will be turning like a wheel, the alternator and power steering pump etc. The compressor if it's not on the outside of the pulley wont be turning. It's an electric clutch and when it's turning on and off it makes a click sound and the idle of the car will change for a moment. There will be a wire leaving the clutch leading to a plug that's where you disconnect it to jump the clutch to turn on. Here is a picture of what your looking for. If you have a test light one side of the plug should be hot. It would be good to check that.
