'97 GMC Sonoma Squealing!!!

Hello Everyone,

I have a '97 GMC Sonoma w/ 4.3 Liter V6, it only has 98K miles. For some reason something under the hood is squealing all of the time. I used my stethoscope to try to find it but I can't figure it out!!!! I've replaced all of the tension and idle pulleys, I've replace the alternator, I replaced the water pump and it continues to squeal!!! Can anyone give me any ideas of what to look at. Thanks!!!

Just call me Sean

That just leaves the a/c compressor. Take off the belt and run it briefly to make sure it's coming from the belt driven accessories.
