The AC clutch on my 2000 Cavalier is very noisy when the AC is off. Can you clean/adjust the clutch or does it need to be replaced. It is quiet when the AC is ON
I heard there may be an adjustment for this, hopefully someone with A/C knowledge will help....
mine got noisy right before it died

I have been through 3 compressors. All b/c the clutch went. I have had my car for 5 months. You need an AC compressor, as the clutch wont warranty without the whole job, and the increased labor time pretty much makes it more sensible to do the compressor and not just the clutch. I am not sure why it keeps going, as i NEVER use the AC, its a PITA when its noisy scratching clingy stuff starts up, I have talked to GM Techs, and they have no idea why it would happen other than a fualty compressor or installation. Either way, it doesnt cost me any more, as ACdelco has great warranty's
Any cavalier I have owned and/or rented over the years always had a noisey air conditioning clutch and/or compressor. I remember reading somewhere, perhaps in this forum that there is a way to reduce the noise by removing a shield from the bottom of the compressor and adding some white lithium grease to the shaft. Keep in mind this is second hand information.
At the very outside edge, there is a plate on the outside of the pully. I am guessing this is the outer of the clutch. anyways, it was just sitting there real still, and the pully was spinning, but the plate itself will turn, if you put you hand on it and spin it. I took and sprayed some lithium grease on it, and the noise quieted.

That last statement was supposed to be a quote from the url.
You know the clutch is gone if you take off that plastic shield and there is metal shavings.

the reason it happens is BECAUSE you dont use the a/c. in order to keep the clutch/metal disc clean, it needs to be used almost once a month. if you use the defroster, it turns on the a/c (even if you have it set to 100% hot).cycle the compressor, and it will actually last longer.
