Hi I have a strange problem with the air circulation in my 2010 prius. The vents are stuck in one position. When I try to go to different mode (windshield, floor, etc) it doesn't do anything. This happened when I was alternating between windshield and other modes to get small parts of glass from the vents (car had a windshield damage due to a "meeting" with a deer). Anyway, I don't know what could be wrong. Is there a motor that overheated (due to constant switching of modes)? Is there a piece of glass blocking the system from switching? I'd appreciate any feedback. Thanks
