Replacing the air-conditioning system regulator and flashing display

NOTE: If the air-conditioning system regulator is replaced, the display flashes after the ignition is turned on. In this case, the system test must be carried out first. The air-conditioning system regulator hereby learns the upper limit stops of the drive motor and the entire system is checked simultaneously!
