Mitsubishi Outlander 2011. AC is working well, heating working well. Air is coming out from all vents except front panel center vents. The Air Flow switch/knob however is not responding to the position it is put; i.E. If put on the position for front panel air flow, air comes out full on the leg and windshield.
The flap that directs the airflow between your front defrost and those Center vents sounds like it is become disconnected from your control
SOURCE: front panel temperature control switch
Very likely the blend door is broken. This door is mounted beside the heater core, blends cool air with hot depending on the position of the door. At the bottom of the door at the hinge point, there is a gear and coupling driven by an electric motor to position the door. The coupling is a drive much like a square drive ratchet and socket made of plastic and often cracks allowing the drive to turn without changing the door position. I've heard you can drill through the outer housing and put a screw in the door through the drive gear, but you would have to know your way around this area well.
I repaired mine by replacing the blend door, a big job at best. The entire dashboard must come out to access the top of the heater core housing which must be removed.

The climate control was poorly designed on these cars.
There is only heat on the floor and defrost settings, due to the layout of the ductwork.
SOURCE: Very low air flow through vents despite the fan working well
It is very likely that the Air conditioner evaporator core is restricted due to leaves or some other object may be blocking air flow like a plastic bag, does it do this on both outside air and recirculation setting?

You probably have a vacuum leak on the passenger side. its a small plastic hose some times they come unpluged from the engine. or brake.

THe blend door seems to be stuck. When you change settings from defrost to floor air or, vent, the blend door opens and closes directing the air to the place you want it to go to. I have had some success spraying a lubricating oil such as WD40 under the dash on the blend door. You need to get under the dash with a flashlight to locate it. It looks like a flap. Spray it with a couple of shots of the WD40. Go easy on the spraying as you may be inhaling the fumes. Keep the doors and windows open to minimize the fumes. Wait about 1/2 hour and try the A/C functions. (defrost, floor, vent air)
