Picked up my son's Mustang from shop (needed inspection, no repairs done). It was a little rainy so I turned on defroster and switched fan to high. Air only came out of floor vents. Temperatures and fan speeds were correct. A/C works and cool air comes out where it is supposed to.
My questions are:
Are any of the actuators/blend doors on this car vacuum controlled or are they all electrically controlled?

Where is a good place to start troubleshooting?

Could my son have left something disconnected on one of the control switches when the console was apart to reapair a stereo problem?

Taking the stereo is a hassle, i have a 2006 aswell if get get down on the ground and and like lean on the floorboard you can see the stereo wires and u can also put your have in there might try to do that to see if you see anything unpluged
