I just watched the A/C Leak Testing and Repair part 2 - 95 Jeep video. At the 56th minute Paul had compressed air in the system and then turned on the A/C compressor with the engine running. The readings in the manifold gauges were changing. I didn't know the A/C compressor will work with compressed air inside the system. So my question is: Did he turn on the A/C from the cabin or did he manually supply 12 volts to the clutch to check operation? Thanks.

Hey Charles! Moved this one to the SD Video/Book section, FYI.
I think this is the video you're talking about?
Pretty sure he just turned the A/C on in the cabin. And yep, the compressor will work with regular old air! Won't cool at all, but that doesn't stop the compressor from trying. :lol:

Yep, just used the regular controls inside. Not only is this a nice stress test for the compressor, it is also a way to verify all of the controls work. (inputs and outputs)
Don't be a parts changer!

Thanks guys! Originally my compressor was making noises while idling and when I charged it the clutch engaged but the noise was louder.. Found the bearing inside was shot. Changed it and now the noise is gone. Next I will try to engage the clutch with compressed air. Once that is verified the next thing to do is find the leak using again...compressed air! The money I save on freon going to waste is great!
I used compressed air and the first thing I noticed the air was leaking from the front of compressor with the PAG oil w\dye exposed. If I'm correct I suspect the shaft seal. Its a Calsonic V6 compressor but I don't think the shaft seal is serviceable. Can't find any info online. I don't mind taking the compressor apart again.
I bought the compressor from ebay and installed it. Used the vacuum pump for thirty minutes and turn it off and waited another half hour in which the vacuum was maintained close to 30 in hg. Added two ounces of oil and and about twenty eight ounces of refrigerant using Paul's techniques from his three part series.

I haven't replaced one of those since college, since everyone just changes the compressor. :lol:
