Initially, I thought the chirping was coming from my sunroof on the right side (and i have a post about that). It was only till I coincidentally turned off the air circulation while hearing it that I realized it was actually connected to that - for me anyway. So now, I just keep it off most of the time. I only notice it when I'm travelling over 75 MPH (which is my usual speed but...). If I turn it on at that speed, I hear the chirping / whistling. Once off, its gone.
