2015 blend door actuator clicking

[Todd]

My daughters 2015 fiesta started clicking under the dash this past winter when you shut the car off, today she turned on her ac and all she gets is hot air, could the blend door actuator be the reason that she is not getting cold air?

So I changed out the blend door actuator and the clicking stopped all modes are working as they should, however the heater seems to be stuck on full on hot no matter where I set the temperature dial I get full on hot including when I put the ac on, anyone ever come across this issue before?

The "blend" for Air circulation - is its own separate sensor and actuator.

But when you put it together, did you see where the thermostat for the cabin air temperature was? IF that got damaged or not seated or it's wires pulled, it could explain the problem.

IT's is close by, wondering if it's connector got pulled or something jammed it when you put the trim back on.

Thanks for the input I just checked and that sensor is plugged in, I changed the actuator on the drivers side,
I pulled the glove box out to verify that the actuator on the passenger side was operating as intended and it appears to be operating as intended. I am almost leaning towards the climate control module is the culprit. Unfortunately I have gone as far as I can go and booked an appointment to have it checked out apparently they can hook it up and test sensors actuators etc. off of a lap top.

Ok, so you have your ducks in a row, check fuses too - read the owner's manual on their location - and make sure all the fuses are good - not blown.

It will save you the embarrassment of knowing you could have saved some money - for if the climate control is really out it can blow a fuse and you would not even know it - except for the constant hot/heat setting.

Let us know what you find out.

So I think I got it figured out, I was reading that there are 3 blend door motors, 1 controls the mode that’s the one on the driver side that lots of people are replacing. The other 2 are on the passenger side, one is for the recirculate door it is right behind the glove box super easy to change, the third one is up just above the cabin air thermostat it controls the hot/cold door and it is a freaking bear to get out. What I did was I pulled the ducting for the passenger floor heat, it just pulls out then you can see the actuator the top screw is easy to get out the bottom screw takes a lot of patience. I ordered the part not looking forward to putting it back in. I manually worked the hot/cold door AC works great.
