On my 2007 Kenworth T600 I'm having trouble getting air flow through my vents. I work in dusty conditions and have trouble plugging my evaporator up. So I blocked off the outside air inlet and run the controls on recirculate, but don't get much airflow. The blower motor works on all speeds, cleaned the evaporator, but can't figure out where the system gets the return air from inside the cabin. The blower acts like it's starved for air. Could someone give me some advice on what I need to do?
