I drive a 94 chevy cavalier RS with a 2.2 Inline 4 Engine
I've had this problem for a while with my car for a while and I've just been avoiding it but there's a mettalic sound under the hood that gets worse when i raised RPM's. It sounds like a bearing's going bad. After talking to some people and examining it myself I figure out that it might be something with the AC compressor...I think the clutch is going out on it.
I see that there are AC Compressors on ebay but I don't know what to do. I'm not certified to work on AC systems so I can't do it myself. Should I buy the part and give it to a mechanic to do the rest or what? I just don't want to put a whole lot into this car

and I wonder if they can just take it out and put something else where it was. I don't even use the AC
