I can turn the clutch freely with my hand and the clutch fuse is good but does not work when the ac is on. Does it sound like the whole compressor needs to be replaced? Can I just replace the clutch or could there be an internal switch that has gone bad?
How did you check the R134 to know it was OK when the clutch doesn't work? Is it an XL,STX,XLT or Lariat? Jump juice directly to the compressor at the plug on the compressor. Jump directly from the battery. Make sure the compressor has good ground (Don't know how it could not, but I never assume because assumptions are often wrong). If the compressor doesn't work then, the clutch is probably bad, but they seldom go bad. You can replace the clutch without replacing the compressor, but I would make sure the compressor turns freely before replacing the clutch, if needed, you don't want to find out after replacing the clutch, that the compressor is locked up! I believe you would be able to put a socket and ratchet on the nut on the end of the compressor shaft to turn the compressor.
