Every time I turm my AC, I noticed a shake in the engine as soon as I accelerated. As it turns out, the serpentine belt vibrates wildly when the AC is on. There is evidence of a belt that had broken before I got the car, and I've already replaced the belt once because it was damaged. Is this more likely to be the belt tensioner, or the AC compressor?
