Have the system diagnosed by a qualified shop. AC only happens at a certain system pressure for a given ambient temperature. There is a chart and the tech will refer to that, and not just "throw in" more refrigerant.

I need to replace a serpentine belt on a 2001 GMC sierra 4.8L. I see the belt tensioner for the AC belt, but the tensioner for the main belt is less obvious. There is an idler pulley but it does not look...

it is decieving. if the tensioner has an extension of about two inches from the base, it takes a 15 mm to lift it, be easy, make sure the wrench is not going to touch anything as you release it after taking the belt off
