I believe it’s the pressure relief vents to allow the doors to close. If I hit the back of the seat with my fist gently it will rattle outsider.
Im gonna try to pull the rear seats this weekend
Has anyone been able to locate the RPO Code sticker? Previous Gen was in glove box. I've looked in upper and lower box and even pulled low glove box assembly out and could not locate it.
Still a bunch of crap buy a 60k truck and they can’t finely tune something that is used every day. Does anyone else have a rattle coming from in the cab back in the rear when going over bumps? I have yet to take the time to figure out what that is
