The clutch as a bearing when the compressor isn't engaged that is turning.
If you look close you can see the bearing in the black pulley. These go out
quite often.

That's why the clutch or pulley will turn and the compressor won't.
Then when the compressor is engaged (Via the clutch)it also has a bearing
which rarely goes out.
