My AC cluster has a button that says Auto on it but I can also manually adjust the driver and passenger side separately so not sure if that means I have auto. I mean every vent in the car blows only hot air regardless of the temperature set. Yes, all of the vents switch modes normally. Hmmm ok, I will have someone check into the AC pump failure. I have an appointment scheduled at the stealership in a few days and they're telling me there is a $180 fee just to diagnose what issue it is. 9 months ago I got all the refrigerant recharged so I doubt that is the issue.
