I have no idea what's up with my floor vents. Ever since I got the truck, heat has worked, and when I put it on defrost, the floor vent shuts and I get defrost like it should normally work. My problem is when it's not on defrost, that flap is wide open on the bottom and my foot gets HOT. When I'm on the highway, it's bad. Of course city driving it's not bad, because it's just engine heat blowing through. So what is letting the heat through?
