Automatic air conditioning. New, correct, air conditioner motors, correct adapters. The fan works, but the blowing towards the center does not work. When only the fan is tested, the flaps are opened and it blows normally in the middle. Diagnostics shows no errors, manual adjustment shows zeros. It just keeps reporting error B1901, but that shouldn't matter. Or does it have to do with blowing in the middle?

Carry out the Self Learn procedure as below.
CLIMATE CONTROL SELF-LEARNING PROCEDURE
The AUTO and MONO buttons must be pressed simultaneously within 40 seconds of the ignition being turned to the ON position in order to active this procedure. A few seconds later a figure will appear on the display (in place of the driver's side set temperature) which will count down to indicate the time remaining before the start of the procedure. At the same time (i.e. whilst the count down is taking place) the previous self-learning status is signalled on the passenger temperature setting:
'1' flashes if the previous self-learning procedure failed
'0' indicates that the previous self-learning procedure was successful
This procedure is not carried out if any of the above mentioned buttons are released whilst the figure on the left hand side is not zero (this is designed to check the outcome of the previous self-learning procedure).
Exiting the procedure zeroes the 40 second counting period from when the ignition is switched ON, to allow the procedure to be repeated without having to switch the ignition OFF.
Each time a new control unit is fitted, the flap actuator learning test must be carried out using the diagnostic equipment and the unit must be personalized through programming.
