My 2000 Volvo S70 non-turbo's air conditioning isn't running consistent. The cabin air flow turns off when I'm idle , along with the a/c compressor (I can feel it turn off as well). It picks back up and the air flow increases when I start accelerating. I've put the car in neutral and given it gas to see if that would work, but it doesn't. It only wants to flow when I'm moving. These sypmtoms occur irrespective of whether I have the control on "Auto" or on the manual fan flow. Plus, the air flow is not as strong as it once was when it is working. I live in FL, so during the winter, this isn't a huge priority, but summertime's just around the corner! HELP!
