most likely your a pillar trim is coming up a bit at some part.

I had a similar sound and it turned out to be a piece of flimsy cardboard paper stuck in the area by the windshield wiper. Some idiot put an advertisement for dry-cleaning under my wiper blade but it must have been pushed so far down that I couldn't see it when I looked at the car. So annoying. Anyway, lift the wiper and take a peek. You never know Good Luck

I had the noise as well and the rubber trim on the a pillar was the problem (where the a pillar met the roof)

Mine was the pillar was separated from the windshield. Removed it and added a bead of silicon glue on the outside edge - never happened again. Easily removed it with a blade when switching to HKFEVER's carbon fiber pillars.

What Plack said... Same issue with mine, first A-pillar whistled, second creaked, found out neither had any adhesive/sealer between the cover and the window. Replaced with CF covers and added a bead of silicon adhesive, problem solved.
