Hey guys, I have a 1999, with the auto-climate control. I have heat/cold air, and all fan speeds work without any issues. The problem is, I can't redirect the airflow to the floorvents or windshield defrost vents, when the corresponding button is pressed on the panel. Usually I could hear a faint motor sound that probably moved an internal vent routing barrier as I would switch between the airflow settings. I'm sure someone else has had this issue and has a part number description. Any help appreciated, thanks.
