Ok not sure how much we can do over the net on this one but let see what we can figure out. Ok let me ask some questions first. Is this an extra cab truck and if so does it have a bug sheild that was recently installed that is a metal one? Secondly have you checked to see if this truck has a cabin air filter system if not check that and see if the filters are dirty. Lets start there and see what happens. Get back to me on what you find.
