    A/C making loud squeal noise when on low setting when starting car

    It just seemed to start doing this. Seems to only be making the noise when i first start it up when it is cold. I have a 2011 with 10K miles on it. Anyone have any idea what would be causing this? Its annoying bc its loud in my car when its squealing. When I turn it up high it seems to almost go away but i can still faintly hear it for a few minutes.

    Loose belts on the AC compressor?

    Hard to tell without actually hearing it.

    the 2011 has the stretch belt on the AC....if it is squeeking, I would suspect the AC compressor clutch, and take it to the dealer to get it checked out.

    Turn on the AC after you start the car not the other way around.
