Both blend door actuator locations needed

The left side actuator is on the left side of the HVAC case, you can get to it from the drivers footwell. It's above the accelerator pedal. Remove the screws and it comes free. Install the new one and tighten the screws. The right side is a bit harder. It's behind the airbag module. To get to it you open the glove box, remove the two bolts that hold the airbag in the dash and push up on the air bag module. With it held out of the way you remove the screws from the actuator, reverse the process to install the new one.

Nope. The bag itself has no sensors in it. If you wish you can pull the fuse for the bag system, it's in the fuse block under the left side of the dash. It's fuse F25. With it out the bags will not have trigger power. Just be sure to reinstall it.

You are welcome. Please return anytime.

Take a look in through the glove box opening. The actuator you are looking for will be on the left side of the opening. Behind the area the airbag was mounted.

There is one on the end where you show but that is the recirculate actuator. The image shows looking at the rear of the dash. The one you have in your pictures is the recirculate actuator at the far left of the image. The temperature actuator is farther over. It should be visible in the top left of the glove box opening. The second image shows the blend door at bottom left, mode actuator above it. Then the passenger blend door on the opposite side of the case and the fresh/recirculate actuator at the top right.
BUT something I didn't ask and just assumed from you asking for both blend doors, Does your car have dual zone heating where you can set passenger and drivers sides at different temps? If not then that is the problem, it only has the single blend door actuator above the gas pedal. Then the mode door above that and the recirculate on the other end.

Okay, if it's single zone there are a total of three actuators. There are two on the left end of the HVAC case above the gas pedal. The bottom one is the blend door which controls the air temperature out of the case. The one above it is the mode actuator, it controls where the air goes, either floor, dash vents or defrost (or mixes of those depending on setting) the one on the far right that you took a picture of is the recirculate actuator. It controls where the air comes from. With it in the normal position the air comes through the outside vents and into the case, with it in the other position it pulls air from inside that cars body and runs that through the case.
If you cannot select floor/dash/defrost air then it's the top unit over the gas pedal.
If it's that you cannot control hot/cold air temp then it would be the lower one on that same side.
If you cannot control if it's outside air or inside air then it would be the one that you had in your picture.
The sheet you got from Ford shows the blend actuator on the left side and the recirculate actuator on the right.
What is the actual issue you are having with the heat/AC?

Okay, that would be the two actuators on the drivers side. The blend and mode. You should be able to watch the linkage on the mode actuator and see if it's moving as they use external plastic pieces to move the various doors. The blend one however just slides over the shaft behind it so nothing to really see.

The passenger side would be the recirculate door and it's working. Except if you had the dual zone heat/AC. Then there would be an actuator as I originally said.

The blend door number for your car should be # 6E5Z-19E616-B and is in the second image while the mode door unit is # 6E5Z-19C772-A and the last two images
The blend door part is a bare actuator but the mode door has a cam assembly attached and those like the come off or break.
To replace them you need to remove the lower motor first, so the blend door, then the mode actuator. To reinstall you want the mode door pins to fit into the slots on the cam on the back of the actuator.

You should be able to get to it from underneath, it's a tight fit but doable. You can pull the lower trim if it has that panel, some do others don't. Then you remove the lower actuator, it's in the way, once it's out then it's just the screws that hold the upper one you need to change. I normally do them laying on my back on a board stuck between the seat and door. That way you don't need joints that bend the wrong way.
