When my '94 RSW is idling or just driving around town, there's some part of the a/c up in the dash that sounds like it's trying to open/close a damper (???) and it just keeps cycling. It does this most of the time when the outdoor temp is close to what I'm trying to achieve in the cockpit. It doesn't do it when there are extreme temperature differences of I'm running down the highway. Any thoughts?
Thanks,
Ed
