2014 A/C not changing direction
Friend of mine has a 2014 F150 FX4 and a while back his A/C and heat wont change direction and only blows out at the floor. we took the dash apart and replaced the blend door actuator and now when I select the head vents on the controls it blows a very tiny bit out of the head vents but the rest at the floor still. Im thinking maybe the door itself is stuck but want to see what others have to say about it. heat and A/C both work as well as dual climate, it's just not changing direction. Any help is appreciated!

Blend door actuators have nothing to do with the outlet selection, they're for temperature control (reheating or bypassing heater core).
You need to look at the mode door actuator and see if it and its door is working or not.

Those actuators, blend air and mode also need to be allowed to self calibrate after install. DO NOT turn the key on before they are installed or you will lose proper orientation.
From the Ford shop manual.
The purpose of the module actuator position calibration is to allow the HVAC module to reinitialize and calibrate the actuator stop points. To carry out calibration, carry out the following steps.
Remove Body Control Module BCM fuse 46 for at least one minute. When the ignition switch is switched to the ON position, the HVAC module will initialize and calibrate the actuators. Calibration of the actuators will take approximately 30 seconds.
Reinstall BCM fuse 46. Turn the ignition switch to the ON position and wait 30 seconds before verifying correct mode door actuator operation.
