I have a 2013 S8 and on the way home from work today the front AC vents are not blowing any air. The back vents are working just fine. The air is cold in the back. I've tried opening closing the vents, turning the system on and off, turning off the car. Can't get it to work. Is there a fuse for the front AC? How is this even possible? Its like the front 2 zones of the climate control some how got set to off and wont turn on but the back is cranking away. Any help would be much appreciated. Thanks in advance.

Both of my D4's had an issue with passenger side vent. It was a small motor underneath the dash that control inside flaps. That could be a good place to start.

With VCDS you can both look for any specific codes for moving doors and such, and run a test routine on them to check function.
