Had some free time to diagnose my A/C. Had the car for 3 years and it has never worked, but never really cared as it is a convertible. Put gauges on it and it is basically empty and obviously the clutch does not engage. Checked out the compressor - big question - Shouldn't the compressor spin fairly easily with the car off (I know the clutch isn't engaged because the pulley spins fine when running)? Just trying to figure out up front if the compressor may be locked up. Thinking they knew this and may have evacuated the system so the clutch never tries to engage. I did note this car already had the compressor swapped out once under warranty. Thoughts?
