Wind Noise Reduction around Windows

[BranZ]

What is the best approach to eliminate or reduce wind noise in a 1988 suburban. The seals are good shape. The problems is that it was noisy new and still is today. I have seen some people switch the side mirrors out. Does this help? Also, would the plastic vent pieces that go around the windows help. You know the ones that allow you to roll the window down an inch or so. I really do not want to go this route but I want the noise reduced. Thanks for your input. BranZ
