Remove the blower and I can put my hand in there to feel the door open. I can manually close it with my hand and heat and cold will flow with no outside air? Basically recirculate only with heat or cool.
I ran the second test scenario and got no errors. The air will switch from defrost to front to floor fine. It is not hot or cold just current outside temperature. Any other thoughts on solutions? Thank you for that diagnostic link!
I have a 2003 expedition. The front fan blowers work, but will not blow heat in the winter or AC in the summer. It is the outside air. The back blows cold air and hot air. I replaced the front actuator between the glove box and radio. Still ambient outside air. Anyone solve this before?
