I have had a random rattle that sounds like it's coming from behind the driver side AC vent. That or the wiper area, I could tell it was wind related. After our last road trip it was very prevalent and even the wife noticed...so it was time to find it. She hopped in the driver seat while I ran a leaf blower into the front end at various locations waiting for her to signal that she heard it. It wasn't until I hit the wheel well that I got the thumbs up. The plastic clips that hold the inner fender liner were loose. I put I tie wrap under them for now and the noise is gone. It is funny how sound travels because sitting in the truck you would swear it was right behind the dash.
This has worked for some or try..
