In response to Bret Bodas answer to A/C Shutoff

Great, so the A/C is turned on, the clutch is receiving voltage, and the compressor is not working, this means you will need to replace the clutch. You can get just a clutch, but you will find that a new compressor w/clutch is very close in price, and with labor and the miles on the compressor it doesn't justify replacing just the clutch.
