Sooooo the sensor came today. Fitted it…. Still no hot air 😔 I don’t know what else to do. I’ve read some people saying they had cold air then turned fans on full then hear a loud pop then hot air comes out as a door is jammed or something? Is there a door of some sort I can manually turn to open a flap to let hot air in if it’s a thing? Also I know it’s probably fine but the heater blower resistor, is it meant to be warm or cold or hot? I have an original one in and took out earlier and was near on cold but don’t know if that’s because of the cold air flowing around it?

Each of the flaps is connected to one of the actuators on the outside.

If the flap is no longer connected to the actuator mount then it's pretty much impossible to move them.

The flaps seem complicated but actually there aren't that many of them. On one side you have the air diverter flaps which switch between face, feet and windscreen. On the other side you have the temp flap which either allows or restricts airflow through the heater matrix. And you have one final flap right at the top, that one cuts off outside air when you select recirculate.

I think the only flap that could cause this issue is the temperature one which should be the one with the actuator that you changed? This is what I mentioned before when you couldn't fit the actuator, that maybe the flap had rotated too far, which is why it wouldn't fit.

The fan resistor will get hot in use, but the airflow keeps it cool.

Ok. The actuator I changed was the directional one as you said that guides air to screen, face or feet. I can’t seem to find the other one people bang on about under steering column. I’ve removed all the panels said and there’s nothing there. 🫣

Somebody posted this like 7 years ago. I’m guessing I need to delve deeper and behind the air bag to try find this one. Great…

1 actuator is by the drivers left leg (by the drivers left foot is a panel with 1 screw and some clips) it's on the right side of the heater but the leg air bag is in the way (I managed to remove the actuator with a torx bit and a 1/4 drive spanner and left air bag in place) this controls the hot / Cold flap this is the one that broke on me

Ah ok. I can't remember exactly where it is on the Fiesta but will try and find a picture of one tomorrow when I'm on the laptop. I usually use eBay to search for HVAC boxes with loads of pictures to confirm this sort of thing. You're welcome to give that a go yourself in the meantime.

I've had a quick look on ebay this morning but they're all manual dials boxes unfortunately. No use here as the climate control version is different.

I finally have hot air. Temporarily. I removed the actuator near steering wheel. Had to cut a small section out off dash to unscrew it but I can live with that. Soon as I pulled off actuator the plastic arm fell naturally fell down and the hot air was there! I almost cried with joy. Now to find replacement, what number on the actuator is the part number I need do you know?

The Ford part number is roughly in the form of AAAA-AAAAA-AA.

But if you're looking on eBay then people list them with whatever number they see on them anyway.

Found it. And I’ve found a matching part on Amazon. Coming tomorrow 😬

All done and sorted. New actuator came. Fitted and works. Thank god. No more annoying messages from me. Want to thank you for your help throughout. Appreciate it 👍🏻

Excellent! Good to hear it's finally fixed. 🙂
