I have a 1995 Ford Ranger 2.3L It Runs fine but when its cold out the belt makes noise. It sounds like its coming from the A/C Compressor. Is this something that will go away when it gets warmer outside or will I need to get it fixed? How much do you think it would cost? I took it to a tech. at the dealership I work at but it stopped making to noise when he checked it out Any Suggestion Welcome!
