When my truck reaches 70 mph it starts making a flapping noise by the drivers side windshield door frame brace. At first thought at first that the front windshield might not be sealed tight but it was checked out and alright. I also checked the black rubber strip that covers the hood bracket bolts. Again this was not the problem. The noise is not coming from the door weatherstrip. The sound seems to be coming from inside the windshield door frame brace.
