I have a whistling noise from somewhere???? I know that is lame and probably not enough information but I cannot detect where it is coming from. It is not from the sunroof though it is louder when the sunroof is open. I can also hear it if I drop the windows whether the sunroof is open or not. It is not the trim around the windshield because I had the windshield replaced for a crack and the whistling is the same. I guess I'm hoping someone else has had a similar noise and can point me in a direction to look for possibilities.

Thanks in advance for any help.
