Hey all, having a issue with my 2005 Navi. The heat blows hot, the A/C blows cold, but it all comes out of all the vents - defroster, dash vents, and floor, no matter what the auto climate is set to. I'm assuming there is a widget that directs the air to one vent or another, but I have no idea where to start with this one.

Could it be an electrical issue? I would think that any issue with the HVAC would cause the display to be inop, but who knows? In my case, the heat is bloody hot, the A/C is freezing cold, but it will not switch between vents.


Any help is appreciated!
