I dont know if this can help:
I had the right connector wiper motor TSB done this summer. Upon taking my car back, I have notice that the exterior black molding that cover the whole base of the windshield (and the wiper motors) was not clipped/snapped correctly back in place. I had to do it myself. Theyre was a good 1/8 inch of open space between the molding and the base of the windshield. The molding/trim piece should fit very snuggly against the base of the windshield.
Doing this, I also noticed that the 2 large vents located near the wiper arms had loose cover on them. I have secured the cover so they dont jiggle anymore.
While upgrading my air filter to a K&N, I have noticed that the battery cover was loose aswell...The cover is in 2 pieces. You must secure the rear part first, and you are going to love this if you got big hands. Once the rear part is firmly secured, you can attached the front part to it.
Doing this got rid of a weird buzzing giant fly like sound I had when accelerating with the car. And no, it wasnt the actual car engine noise :)
Also, check for loose roof molding ''rails''. One member here had one of them ''fly away'' due to faulty assembly. I have a loose one on the right side but I dont think it's loose enuff to fly away. I keep an aye on this gy every time I wash the car to see if it becomes ''looser''
