It's very high pitched, not a rumble, and intermittent: it comes and goes, chirping several times a second, occasionally lasting for a couple of seconds. To check belt deflection set a straight edge across the top of both pulleys, push down on the belt and measure the distance between the belt and straight edge. Just like many other parts of a car, the noises can indicate some problems or potential problems. It is used for slowing or stopping a moving vehicle, wheel, axle, or to prevent its motion, most often accomplished by means of friction. With the vehicle in idle and the AC on Max AC the vehicle has an intermittent squealing sound. The defrost is also not being used. If you don't hear a noise, proceed to step four. Looking for suggestions, I have a 2000 C5 and recently the a/c compressor started making a squealing noise when turned on. For AC Clutches & Compressors, shop Advance Auto Parts.
