I have the 2007 tc model. When the car is in park but running there is a very small noise coming from either a belt or one of the pulleys. It is very low and almost not noticeable. However, once you put the car in drive, but not driving (foot on brake) the sound is loud and like crickets. But..once you start driving the car..there is no sound..at least not from inside the car. Any ideas? I know I will replace the belt but how can I diagnose a pulley?
