My 2021 Longhorn floor vents just quit working today. Just turned over 30k. Thought they had this issue taken care of from prior years. Worried now I will need a new box. What I was wondering since this a dual climate control does each side have its own door and actuator and if so how could both fail at the same time? I did stop a my buddies garage and he did a scan on it came back with no codes so he did a recalibration on dampers and still nothing. Thoughts?
