you can control the vents by hand by the gas pedal there are a few levers and stuff fiddle with those..........also you might be on recirculated air make sure you are on fresh air it's the picture of the truck with the arrow coming from the outside in.......the control for the fresh air is on the fan motor box on the pasenger side...also there should be ducting running from that fan box to the heater box you shouldn't be able to stick your fingers into it lol
