It took care of the clicking noise.
It took care of the clicking sound coming from the heater controls. It works perfectly and was a good fit. The videos showing how to replace are very good. I plan to purchase more car parts from 1A auto.

Great part, misleading video
It was exactly the right part and fixed the problem. The video that prompted me to get the part ended up to be not effective however. It gave me confidence to buy the part in faith that I could install it. I tried the method offered but it did not give me the access I needed. In another video they used a ratcheting box end wrench. With that tool I had just enough room to turn the 3 {not two as in the video) screws and replace the part and screw it into place. Once I got the right tool I removed one panel and did not have to remove the other two as your video showed.

Heater Blend Door Actuator
It came very quickly. Fit perfectly.
I watched the 1A install video and it made it a simple replacement. Without watching the 1A video it would have been difficult just to find the actuator. I have bought many, many parts from them. All fit and work perfect. From brake pads to rotors to brake calipers. Fog lights and now this actuator. I'll always buy my parts from them. Plus prices are always very fair.

I will definitely order again in the future if and when I am in need of a part for my vehicle. I have also recommended 1A Auto to others.

Awsome item, it fixed my heater problem
works just like the original fixed my heater problem, be sure to match with the item in your vehicle because shaft on the item was different from the one specified in the Ford repair manual.

I had a clicking noise and knew it was the blend door actuator since I have had the problem previously. I had AC but no heat. The clicking noise is gone but now all I get is heat. How can that be?
You might check to make sure the actuator is getting power.

What could be wrong with my 2006 Ford Explorer Eddie Bauer Edition V6 thats blowing warm air and sometimes I can hear the air go low and back high?
Blower motor going bad. If it was the blender motor you would hear it.

No heat on floor, good air flow at other settings, does blend door actuator control this issue?
When you are experiencing a lack of heat coming from one piece of the vents (in this case being the floor), the most common issue would be that you need to replace the vent mode actuator which controls the direction of which vent(s) are pushing through heat or HVAC.
