Re: Need advice from mechanic
Not beyond the realm of possibilities. Without hearing the sound, it's guess work on our part, but if either one is seizing, particularly the compressor, it can put a drag on the engine. To rule them out, you can pull the serpentine belt and see if they rotate freely. If the AC is not working, and you have no plans in repairing it, it might be wise to pull the signal to it so that the compressor doesn't get engaged.
