The compressor is bad. I have the same problem. Apparently none of the tahoe's compressors are worth a ****! im having to replace mine too. You have to change the compressor, the accumulator/dryer, orifice tube and flush the lines. If you look on ebay you can buy a complete kit to change it all for about 300 bucks. The dealership tells me that you need to change the fan clutch as well. They told me that the reason for the noises is the fan clutch isnt working properly and it lets the compressor get too hot causeing higher pressures in the compressor due to the heat. They called it liquid slugging I believe. Mine doesnt break the belt but when you give it very much gas it makes a squeal and then a grinding noise like your trying to put a standard transmission in gear with it running without pushing in the clutch. I asked if you could just change the fan clutch and they told me no its too late, you have to change the compressor and dryer/orifice tube.
