Hello,

My friend is having trouble with the blend door actuator in her Ford Fiesta
VII 5 doors 1.0 SCTi EcoBoost 12V mHEV S&S 125 cv
Engine = B7JB, Year = 2021


I replaced the blend door actuator

I aligned the arrow before installing the white gear

but it works for two or three days and then breaks down without even touching the temperature control knob
I've been reproducing it several times

It's not a clicking sound but rather a sound like the engine forcing and then releasing

I found online that you have to turn the ignition on without starting the engine and recalibrate by holding down the AC button for 10 seconds
There were a few very faint noises, and the temperature on the screen was flashing, but that didn't solve the problem—it's only blowing cold air now, no more hot air.

Does anyone have any information or know the procedure for this?
I've also found that sometimes you need to use FORScan to recalibrate—is that the case?
I've already used this software to activate the backup camera I installed


Thank you very much
Sorry, English isn't my native language
