Default Re: need help...'03 H2 with AC problems

As was mentioned previously, try removing the serpantine belt and try turning all of the pulleys and see if you notice any dragging or roughness. It is most likely the idler or tensioner pulley that is making the noise. They are both easy to fix...you can replace them yourself.
