The 2004 double cab Tundra defroster only works on outside air, when in traffic the carbon monoxide comes into the vehicle making it dangerous and unpleasant. There needs to be a solution to clear the windshield with recirculated air. I do not enjoy driving the vehicle when the windshield fogs up and I have to use outside air to defrost.
