It's coming from that same area.
Well, that would be the A/C compressor, so try removing the A/C belt and see if the noise goes away. If it does, you've just found the culprit.

I know some belts when new can cause a different pitch or noise because they are new. If it only started after you replaced your belts. Or like stated before a bearing could be going out.

This, but I don't think it's the compressor.

Take the AC belt off and see if the whine goes away. It sounds like it is the bearings in the AC idler pulley are going bad. Common and cheap and easy to replace.

I wanted to report my experience with this. About a week ago a whine started up suddenly and remained, but everything else ran fine otherwise.

It was the AC pulley bearing. My cousin and I took the front belt off first. I started it and the whine continued, but it was still difficult to determine whether or not it was the pulley or something up higher. Since he lives near an auto parts store we took a chance and just went and bought a new pulley bearing and popped it on there. No more whine.

It's an 2002 WRX, so it had been on there a long time.

i'm betting on AC compressor clutch

one thing you try, if it's above 32F outside, is putting the AC on and off to see if it's changing the sound..

it won't work below 30F i think as the compressor has a sensor to stop it from working when it'S cold so it won't get damaged..

also, put a LONG flat head screw driver on the compressor and put your ear on the other end, do it on the altenator as well and other things you can think of.. it will help pinpoint the source instead of just having a hunch on where the problem is.


EDIT: BE CAREFUL WHERE YOU PUT THAT SCREWDRIVER SO YOU WON'T GET HURT..
