Pretty self-explanatory title, I can't move the air flow from the mid/head level. I press the buttons and the lights change, but I don't hear anything inside and it stays where it is. Anything I can do easily to change this? I wanna be able to use my defrosters this winter.
I have done some research and heard some possible issues could be a vacuum leak, blown fuse or an issue with the blender door or mode actuator.
