Sounds like the controller box, does selecting the manual defrost (icon above left over selector) work? When mine has frozen a hard reset fixes, but it doesn’t cycle through in that scenarioI've had the Phoenix radio installed for about a year now and I have only recently noticed an issue. All A/C controls work including the physical buttons, however changing the airflow position does nothing. It doesn't matter if it is set for foot vents, dash vents, or defrost, air only come out of the dash vents. I can press the button and the icons cycle and light up as expected however there is no change to the airflow out of the dash vents.
I realize this could be a mechanic issue but I was hoping someone here had and hopefully fixed a similar issue.
