    I had this faint sound for a few days that sounded a bit like the wheel on the Wheel of Fortune. I took the car out today and the sound is louder now, sounds a bit like a quiet helicopter under my dash. I notice it seems to let up when I have my foot on the gas pedal and is worse when I am slowing down. I can only hear it inside the car.

    Any idea what that might be? Is it dangerous to drive like that?

    Do you have your HVAC fan on??
    Do you have leaves in the vent??

    I had it both on and off, didn't seem to make any difference. I don't think it is leaves, the sound to me is mechanical.

    Could it be the motor mounts are weak or exhaust pipe is flexing?
