Thank you Justin, the center blend motor has stopped working. Now I have another issue.
When the car is idling, it does not produce cold air but as soon as I start driving (rpm goes up) I get cold air.
I just came across this post. I have the same issue. I used to hear a gurgling noice for awhile before the front center and side vents stopped working.
I see the stopper motors and the one behind the center console (difficult to get to) seems the only one that’s not moving.
I have a 2008 s-type
