Moaning sound from windshield area

For all Montana owners (SV6 and previous) who are experiencing a moaning sound from the windshield/dashboard area at highway speed especially in crosswinds, here is what fixed it for me in my late '04 Montana:
Open the driver's and passenger's doors to expose the edge of the windshield. There you can see where the edge of the moulding the windshield sits in and the edge of the door seal meet. Take a screwdriver (not a too sharp one) and tuck the lip of the door seal under the lip of the windshield moulding; start at the top or bottom and work to the other end. That's it! Fixed mine in about ten minutes.
