It's not cheap, about a grand I think. I had one replaced under warranty as the clutch burned up in it. Might want to try the warranty route if still covered. At least point out the issue to the dealer so it's on record.
64-52-6-918-122 is the part #. List is around 900.00

Damn that is not cheap, I might need to try the slightly pre-owned route as my warranty has now expired. Buying used for an item like this is a gamble though. I have seen them used for $200, but they were a few years old and ~35K miles.
It might be a decent option though.
Oh BTW, how did yours go out? did it make any noises, smells, etc. Did the clutch just burn up and then stopped turning the actual pump/compressor, so it suddenly stopped cooling? -
My a/c compressor has been making that whining sound just as you describe for the past 20,000 miles and it still works. When it fails though, I'll get one of those idler pulleys and remove the compressor.
-
So, if you are going to remove the compressor and not replace, does that mean you do not use it now? So it makes the noise all the time, even when off? Hmmm, mine only makes the noise when the AC is running.
-
That’s just the way it is. You’ll also notice it doesn’t roar at night. If it is cooling that’s all that matters. So far malfunctioning behaviors haven’t been mentioned, so enjoy it while it lasts.
-
No problem on enjoying it while it lasts, I am certainly not going to touch it until it dies. Just wondering how long I might have, and if this is the predominant failure mode.
-
Mine sounds like a Harrier jet. I am just going to wait and see how long this bad boy lasts........

Does the sound change pitch along with engine speed?
-
Yes, barely noticeable at idle, and then can really hear it above 3.5K. And so from the start I knew it was something hanging off the serpentine belt: AC, alternator, idler pulley, etc. Then it was pretty much locked-in as AC compressor when turning off the AC made the noise completely stop.

Thanks for that, I will check out the link. And to be clear the AC system is cooling just fine. It is just getting noisy. Maybe I need to make the AC noise my new shift point for city driving. :^)

Yep, that nails it. I may be the odd example here, but you can hope I suppose. Those symptoms are the same as my Cooper had for a year or two, then it stopped. That is, the noise went away. It's been another three or four years now and still working. I thought I'd lost the compressor last spring but it turned out the body shop overcharged the system when they put my car back together....fixed the charge problem and it's working fine again.
I asked about the noise on NAM about four or five years ago and the overwhelming chorus of replies was something like "that's your supercharger, DUH!" Me: "Ummm, my Cooper doesn't have a supercharger." Reply: sound of crickets chirping. -

I have the same problem. It gets worse when the AC's running full blast, and definitely in lower gears at higher RPM's it's worse. Almost sounds like a vacuum cleaner. This happened to me last summer, and then it went away for a while... also known as winter. :lol:
-
My system is exactly like what you are all describing. Only has the whine when turned on, it is rpm dependent, louder above 3.5k, and is more pronounced in hot weather.
-
While misery does like company............ That noise is NOT normal and we should not be experiencing this compressor whirring noise, even if the unit still works fine, at least for the moment. Not that I can do anything about it, but this is a clear reliability issue. Nothing to do but wait for the defect to mature into a full fledged failure.:mad2:
-
I'VE HEARD THE COMPRESSORS DO THAT. YOU MIGHT TRY AN A/C SERVICE. EVACUATE AND RECHARGE, AND ADD SOME OIL. I FOUND REBUILT UNITS FOR $600.00, 1 YR WARRANTY, WITH NEW CLUTCH.
-
Well, I just paid a visit to my local dealership today and through some effort, I was finally able to reproduce the compressor noise with the tech riding shotgun.
I am now the proud owner of a new AC compressor. Yeah! -
Terry, it looks like the dealer helped you out. That's not am option in my case. What is everyone's opinion on getting a new compressor that is not OEM? I have seem the whole kit: expansion valve, compressor etc for $525. Is this too good to be true? I guess I could ride this out until after winter but in san Antonio that is about one month.
This could be the nail in the coffin as my wife wants me to sell the car now and stop putting money into it.I cannot let this happen! Anyway, thoughts and opinions would be welcomed.
Edit: just realized this was quite a thread necro. -
Before you put in a new compressor, go to the autoparts store and buy a recharge kit. It'll come with a pressure valve, stop leak mixed in, and a quick connect. All for about $20. My AC was just blowing air, no noise and a charge did the trick. Even if I have a leak and have to recharge it once a year, for $1500 to fix it , I can go 75 years before it costs the same
