    whining noise when A/C is turned on

    Hey Guys...

    There is a new problem with my car but I do not know what it is. Hopefully somebody can chime in with suggestions or maybe they have seen this before.

    I have a 6spd 2000 Firebird Forumla with about 90K miles on it. The car runs fine but when I turn on the A/C(not including the settings where it just brings in outside air), I hear a higher pitch whining sound from under the hood. The moment I turn off the A/C, the sound goes away. This happens whether I'm at idle or driving at any speed, gear, RPM.

    Any ideas?

    Thanks!
    Ben

    Bad belt or bearing, would lean towards compresseor. Pop the hood with the car running and try to pinpoint where exactly its coming from.

    It sounds like its coming from where all the belts are. I used my digital camera and made a little avi of the sound with and without the AC turned on. The quality is not that great but you can hear the sound.

    Thanks!
