If you look at the front of the ac compressor under the hood, you will see where the belt rides on the compressor pulley. Here is a picture:
Now if you notice, there is a pulley and inside the pulley is the clutch. With the AC off, the pulley will spin with the engine running and the center (clutch) will stay still and not move. When you turn the AC on, that center (clutch) will lock up with the pulley and begin spinning. That is what ment by the compressor running (cycling). It will run for awhile, then go off for a few seconds, then back on. That is the cycling part. Check that and let me know what it does, or if you have other questions.
