65 skylark fact A/C I simply added 134A and oil to my system that had no pressure at all coming out of restoration, and replaced my expansion valve because of broken tubing. Turns out I had a significant leak in the system at the dryer connection. But, the A/C air wasn't very cold even at the first charge with 134. I know there is a lot more that should have been done. I ran it anyway through the summer. My compressor failed. It wasn't that the compressor itself seized up. Instead, the bearing on the front for the pulley was destroyed...actually locked up. It did have oil in the sump. The compressor seems fine with the clutch disengaged. I think the clutch mating surface is ruined. I expect seals are ruined because it got really hot. I want to fix the A/C system and go back to R-12 I've pulled the compressor and the dryer. I have blown acetone through the remaining system to get out any oils. I also did the same to the dryer. My questions are: What do I do for a replacement compressor? I want it to look like near original, though I don't really care if the A6 compressor is the exact P/N that came with the car. Woudl it be recommended that I go to a scrap yard and pull one from a car that seems to turn OK by hand? Any compressor froma GM that looks to be the right dimensions and fittings? I see other posts here recommend I don't buy a rebuilt one because of poor quality? I assume the same for trying to repair mine, or should I try and where would I get parts? Can I do it? What about the dryer. Again, go to a junk yard and pull any one with right the fittings from the R-12 age? Or, would mine be OK? Buy new one from YO? Maybe post in this forum in the WTB section for both? Thanks in advance.
