My AC clutch just went bad.
Had the same symptoms as yours.
You can buy the clutch bearing from a parts house.
They should have a listing.
First you need to make sure that your clutch is still working and that the AC fuse under the hood is not blown.
The clucth will cost about $150.
I have found a remanufactured compressor for $190.
To take you cluch off you will need to remove the 10mm bolt from the front of the clutch and remove the front clutch plate. There will be a snap ring at the front and then one holding the back part of the clutch to the compressor.
Two snap rings total.
