My daughters Cavalier is making some noise. The noise pretty much goes away when the AC compressor activates. The noise can best be describes as the same as an alternator, or an idler wheel with bad bearings. The noise can be intermittent at times, but my guess is the Compressor bearing has gone bad. Vehicle only has 113,000 KM
Can this be diagnosed by taking the belt off and spinning the AC pulley?
