Already Tried:
Trying different settings on the dash panel and the passenger control. It is like a duct door for the drivers side is stuck on vent.

Hi. You most likely have a bad controller. On the dual climate zones the controllers tend to go out. Before replacing it though you need to ensure that it is not what is called a delta t lock. turn both sides to hot and wait and see if they get warm. Then slowly turn both to full cold. If they still do not work then the controller is probably bad. The controller cost about 250 from a dealer and requires no special tools to change.


If I answered your question choose accept but if you still need more help just ask, I'm here for YOU.
