I've got an '02 explorer. when i am on the highway and have a cross wind, i get a loud buzzing or humming noise that sounds like it is coming from the top of the windshield area. It doesn't happen all the time and i have checked the trim around the windshield and it is all tight. I can't figure it out and it can be very annoying on a long drive. Anyone else have that problem or an idea of what to look at?

thanks

 

same whistling noise issue between 55 and 65. No fix.
