I have a 2014 F150 with a 3.5L and it has a clicking sound in the dash that happens when I select the middle air location on the AC or fan. I thought it was the Blend Motor but I disconnected the power and removed the geared motor and it still makes a clicking sound. If I select the defrost or foot location icons the clicking stops, as soon as the center vent is selected it starts clicking again for about 10-15 seconds. Any help is greatly appreciated. Thanks, Mike

 

There are more than one actuators under there,you just started with the wrong one.

 

Thank you for the response. Do you know how I can find the number and location(s) of those acutators? I have looked on youtube with no luck so any help is greatly appreciated.

 

No such thing as "The easiest one", but one place you might consider to start would be to remove the glove box so you could see the duct work and the doors that are controlled inside them.
