Wind noise from gap near mirror

[David N.]

I've been driving home on the freeway with the top up and noticed something odd. There is a high pitched wind howl noise coming from somewhere in the car, and as I tried to localize it I figured out it was coming from where the door window meets the plastic mirror triangle piece and the rubber trim on the A-pillar (right there at the top of the mirror piece). If I put my finger there it would suppress it, so I'm guessing it's just a little gap or something.

Has anyone else had this problem, or more helpfully has anyone else been able to fix this problem somehow? The trim on everything feels kinda dry, so I'm not sure if I need to re-condition the rubber trim to make a better seal or if there's something else I can do to close/silence the gap.
