Issue / Question:
My a/c belt broke. We replaced it with a belt from an autopart store with no problem. We test drove the vehicle and discovered a aweful noise which was the tensioner vibrating violently. We then replaced it 2 times; one time with an aftermarket one and it also vibrated violently. We then bought a gm tensioner and the problem continued. We have been told the compressor is going bad. It still blows cold air. Thank you for the help! 

Answer:
If you don’t have the problem with the A/C off it may very well be that the compressor is requiring excessive torque to turn causing the problem, this would mean the compressor is seizing internally and will need replacement.
