    Whinning sound near the alternator/AC area....

    2002 Subaru Impreza WRX Wagon

    There is a whining sound from my car. It seems to be in the alternator/AC area (near the pulleys/sprockets)... As the RPM goes higher the sound becomes louder. If i hit 6k rpm there is a crackling sound.

    It sounded like a bad bearing so i thought that my alternator was dead but i just replaced the alternator and the sound is still there.(i really suck at diagnostics) I am thinking maybe it has to do with the AC. My AC has not been working for a few weeks now but i thought it was because i needed a refill.

    Any ideas?

    Maybe the AC clutch is kaput. What happens when the car is running and you have the AC turned on?
    Life is like riding a bicycle in order to keep your balance you must keep moving.

    When i have the car running and i turn the AC on it seems to stay the same no loss in rpm. Maybe its not engaging? there is definitely no cold air coming out of the vents.

    I agree with oguitar, sounds like the AC clutch.

    I took the car in and the mechanic said it was the idler bearing. So he replaced the tensioner for the AC and boom done.
