After watching the videos...I pulled my side vent cover off "DRIVER'S SIDE" and looked down in the hole.
I found this inside...it was not attached to anything just sitting there...It feels like a pieces of packing, but it looks like it should be attached to something, but was not...it was just laying in the hole until i reached in a pulled it out.
I don't know what it is or what it does? Is the purpose to stop water from gaining access to the truck through the vent? Which in turn could prevent water intrusion into the intake? I have no idea?
Its to keep hot underhood air from getting sucked in from the area near the hood hinges. There is some heated that can escape from under the hood.
