Have you noticed on your Edge whether the black trim/pilars between the driver door window and back driver passenger doors are flush with each other? I have noticed that the trim on the back driver passenger door sticks out past the driver's door trim. I believe this is the cause of the window noise. I am actually able to push the trim piece in and it will stick for a little while but it ends on popping back out. I'm going to see whether the dealer can fix this the next time I bring my Edge into the dealer to get it serviced. If your pilar is the same, then this could be the source of your wind noise as well.
