Errors / Flashing air conditioning panel (Climatronic)

Q: How to fix Errors / Flashing air conditioning panel (Climatronic) in Ford TRANSIT CONNECT?

In many models, the air conditioning system (EATC) is controlled centrally from the multimedia touch screen (SYNC 3). Due to a system error, the screen freezes, turns black, displays a blue screen or displays constant Wi-Fi errors, which cuts off the driver from any control over the temperature and airflow in the car. Solution (per TSB 20-2363): Reinstallation and calibration of the APIM module (display module) using a USB drive with a software patch from the manufacturer.
