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. http://www.specialtauto.com/delorean-parts/images/AC-clutch-assy-1.jpg 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.
