Well your system is stuck and defrost mode which is the default mode when there's a problem with the HVAC system. And that's all computer run you might disconnect the battery for 5 minutes and see if it resets itself but if not you going to have to find a mechanic like me with a dealer level scan tool to do bi-directional testing of that entire HVAC system and for my experience on those it's often a control module failure

Thanks Mr Kilmer this helps a lot and thanks for all you do i watch all your videos and im a huge fan. I found one of your videos when i had a problem with my car when i bought it and keep making videos they do make a difference in peoples life's im sure learning more. I feel like people like me waste money because of a lack of education so thanks for everything.
