I am getting a noise from my air conditioner pulleys when the car is cold. It goes away in about 5 minutes. It used to go away after a minute. I have checked the other pulleys on the other belt, they are good. How do you take the belt off for the air conditioner? I reached down and grabbed the air conditioner idler and tensioner pulleys and I can wiggle them a little bit with the belt still on them. Is this good?
