My truck is a 2007 ford f150 4x4 with 5.4 engine

I get good air flow on the feet/chest or just chest settings but not the other settings

Expert:  chris replied 3 years ago.

ok,, on a 2007 F150 the doors in the plenum chamber to control air flow are controlled by three electric motors ,, there is no vacuum used

 

if there is a problem with the system and you have ATC,, push buttons to control your a/c ,,not three knobs like manual a/c ,, then there is a self test you can do on the system

 

so do you have ATC ,, buttons you push to control the a/c and heat ,, if so , I will tell you how to do the self test ..

There is a push button to activate the air conditioning and then three knobs to set fan speed/temp setting/air flow control

Expert:  chris replied 3 years ago.

ok, so there is no ATC and you can not do a self test ..

 

I guess you can take a look at the main air direction motors on the left side of the dash , grab a flash light and get on your back in front of the drivers seat and look toward the center of the dash , up high ,, there you will see a electric motor , its called the mode door motor ,, as you look at the motor , operate the functions of the a/c from floor to panel to defrost and see if the motor is moving or anything is loose
