Get a ladder and check the top of your windshield and make sure the black rubber seal is really doing it's job. Mine was not in front of the driver, and it was allowing a small amount of air to come through and whistle. Also, a small amount of water in driving rain. I posted it, but so far nobody has taken notice ...
