    If you hear it when engine is switched off, most likely alternator decoupler pulley!!! Sounds like something is still running after eng. stops. IF alt. is ok, pulley can be replaced. This is all one possible cause of your noise, others exsit!

    Yes if i turn the car off it sounds like a fan or something but i only hear the noise when i turn the car off. I got to different opinions and I was told it was sounded like the ac compressor was going bad. I got the ac compressor replaced and it is still making the same noise....so I will see what the alternator decoupler pulley does..thank you.

    Thank you. I replaced the alternator and the noise went away. Could have saved money buying the ac compressor.
