Today I finally had it with the tweeter cover noise, so I pulled them apart. I found out that the noise is not only form the tweeter cover, but the A-pillar trim as well. After pulling off the tweeter covers (they just pop right out), and the pillar trim, you can see where the base of the pillar trim contacts the dashboard. The pillar trim has tabs that sit in a slot on the dash, so I installed some self-stick rubber weatherstrip. Also, the surface of the pillar trim's base rubs against the dash as well. You'll see wear marks on them. I used the same remedy, but the thinnest weatherstrip you can find. As for the tweeter covers, clean them up, and use some 3M automotive double-side tape (grey) to re-install them. They'll never move again.....and quiet as a mouse............PS - The pillar trim is a little tricky to remove. The pass. side has screws under the grab handle trim covers, take them out, and the trim pops off. The drivers' side, however, is different. The pillar has a small "badge" that says "side airbag". Use a small pick or screwdriver, and the whole "badge" pops out to release the pillar. Take caution to not scratch the trim.........
