I am the second owner of an 02 mountaineer(rip mom). I believe the mode control is vacuum actuated to change the airflow from vents to defrost. I cannot change mine from vents to defrost. Does the mode control module fail or is It most likely a broken or cracked vacuum line. Thanks for any replies and help as I am going to give this car to my daughter and want to make sure that the defroster and vents work properly
