    Beeping sound with the AC on

    I get a high pitch beeping sound, about every minute(timed it) when driving with the AC on and can't figure out what is causing it. It is annoying. Any ideas what it is???

    You are using AC already?

    Maybe a video of the beeping would help because this is the first time I have heard of something like this.

    Video would REALLY be helpful!

    Is you Airbag intact or is the airbag warning light lit?

    There is maybe 1.5-2 months where we don't run A/C down here.

    I was driving down the road the other day and while ac and radio was on i heard a low bezzing sound and after a cpl of minutes of trying to track the tone down i noticed my interior light was going on and off to the tone so i stopped the car. Opened and closed both my doors. Sound went away and liggt stayed off.

    Is this a "beep" or more like a high pitched "whine"?
    I have experienced the whine on my 91 NA when the AC is on.
    I assumed it had something to do with the pressure of the AC lines?
    Anybody else?

    I use the AC when we are Auto crossing. Gets hot with the helmet on, lol. Yes we are using the AC already here in South Florida , it's been high 80's and Sunday at the AutoX it was 90. The noise is a high pitch beep. It does it about three times and then stops for one minute. Then start again and does not stop until I stop driving and shut the car off. When I turn the engine off, it does it one more time, with every thing off. I don't think I have any thing that would record it and don't think you would hear it on the Forum. If I shut the AC off it goes away any time I'm driving, but still makes the sound when I turn the engine off.
