Hi All
Have the same recurring problem-
When I moved the selector I hear various sounds from under the dash but no change in airflow to different vents.
Took it into a dealership who had a mechanic who also owned a Mystique...he said that there was a "fix" in putting a star fitting (I don't quited know what he is refering to) on the control arm that moves the "door" tha changes the flow direction.
He did that and the fix lasted for about 6 months before it failed again. Now I get no sound from under the dash when I move the selector.....but at least it worked for a while longer.
