I'm trying to pin point if my compressor is making the noise. When I turn the AC on. I hear a very loud ratle after the car is warm. But I hear a very light one in the morning. I also hear a wooooooooooooooom sound from time to time. Whenever the AC is on the engine revs around 100 and the load is very significant. I had never noticed this whenever I turn my AC on. Is my compressor bad? I was doing some searching and people recommend to change the bearing, clutch, and coil. I am planning on doing that but I really need to know if this is the problem. The AC blows very cold air. Theres a very nice guide on changing the compressor clutch, coil on here. Thanks a lot for your help!
