Have you done a diagnostic check for codes yourself. If you get any it might help to troubleshoot. If not suggest you use manual controls during the winter on long drives. Maybe one day you'll find a technician who can repair it. Drive safe.

thanks for the help. i have also some ideea, due to the fact that we have dual zone clima, is it possible that the in car sensor have some kind of error and register wrong to the left and right temp ? is only an iddea

 

Good you also have some idea. Have you tried decreasing the temp on LH side to get more flow from the face vents? Are the LH & RH temps set differently? Looking at the wiring I don't think temp sensors control the RH & LH. The control panel ATC does that just by upping or lowering one or other side. That is why asking if you did the system test on the panel which I made a copy of but forgot to attach.

yes i made the test and i have no errors. i did not check what happens if i decreasing the temp on LH side, i will try. But if i have more blow in this situation for sure i will have also colder air then on RH, witch also is not in my interest. If the sensor is not the problem and for sure it is nothing that is the stopping the air because on manuel it works i see it only an electrical problem that comands to blow slower on the LH

 

It doesn't blow slower on LH. More flow is going to the floor and less to face. The LH blending servo motor & it's commands controls the blending.

Try having different LH and RH temp settings that might get the flow you want. If that doesn't work keep warmer clothing available until repaired.

the hole ideea is to repair what ? if someone can tell me what to fix, i will gladly do it

 

I have given an opinion after spending my time looking over the diagrams and description/operation to try to help you out.

Hire an expert or go with the suggestion in the first reply if you would like.
