So, I almost always drive with my windows up so normally this isnt a problem, but the other day I was driving with my buddy and he rolled down the window as we were going down the high way and little black bits started flying about originating from the air vents. I'm assuming its from the insulation, but I have no idea where its coming from, other than under the air vents, and I don't know how to fix it or what is causing it. Please help!
