There are a couple of actuators that control the airflow by opening and closing the doors inside, one of them control the front vents, I suggest you get a manual to find out which one. This happens when the battery is disconnected and reconnected the computer is not given enough time to reset before the ac controls are turned on, the computer needs minimum of 2 minutes. But you would not know this until it happens by reading the manuals after it is too late like me.
