bruthaman: have you tried running a jumper wire from the battery to the compressor , to give it a full 12 volts , just to see if it still squeals , if its not the belt , see how easy the compressor turns by hand , say about 15 or 20 rounds, if the belt is off you can do this with a socket, with the belt on turn the clutch off, see what it does both ways, belt on clutch off, belt off clutch on , and off, hope this helps.....good luck....
