I have an 03 lancer oz rally (5 speed) with 104k miles on it. I noticed that when I'm sitting in traffic or wherever that when I turn my a/c on while stopped, I feel some vibration on the clutch pedal. When I turn the a/c off, it goes away. I can also hear some loud noises under the hood that my 03 es automatic doesn't make. Does this sound like a belt problem or a compressor problem?
