    heard what sounded like a belt chirping (or a low P.S. Pump, it wasn't) as I was leaving the supermarket yesterday. Give it half throttle, it made the noise, but no noise at a steady speed. Today, it was worse, shut it off for a bit. Thought it was still quiet at steady speed or idle, but I heard a light chirp when I had it running, and opened the hood. Gave it some gas under the hood, made a terrible noise, and saw the clutch seem to slow down, then back to normal speed. I have a feeling I am going to hear, replace the compressor, just wanted to make sure I didn't have any other option. It's been awhile since a compressor went out, but don't recall having nice cold air, and a clutch that turned easily by hand (or is that actually a bad sign?)
    OH.....any thoughts of the best place to buy one? I checked a few months ago for my Dads car (a 79 Lincoln) but saw a lot of folks on Summit, amazon, etc hating the ones they bought, saying they only lasted a few months!

    I have used the Pro6ten. It is about 10 to 20 lbs lighter than the factory unit and it lasted 10 years before I had to replace it. Drop in replacement

    Yeah, I would make sure the belt is tight first, and maybe try some belt dressing. Simple things first.

    I like all the answers you’ve gotten so far. I’ll shut up now. :)
