Window and mirrors not working on Alfa 159. Driver`s door-side

Probably your issue have been solved by now but for in order to help others then:
Replace the whole block of window buttons on driver's door. It that doesn't help - inside the door there is a small dedicated ECU which some purpose is getting windows up or down.

has anyone solved the problem? It's not from the module in the door, it's not from the installation, it's not from the motors, it's not from the buttons, only the body computer I haven't changed.

Knowing how 159 are sensitive to voltage, I would check battery voltage and alternator, if all of the above doesn't help.
Also, try tracing the CANBUS. Probably windows are on a line of their own.

Battery is 5 months old, Bosch S5. The alternator has been repaired. I'll check and share what I find. I'll check the ground circuit and the voltages to the modules.
Thank you

Problem solved. I have a Chinese multimedia on which the CAN module did not detect the buttons on the steering wheel. I put a separate module for the buttons on the steering wheel and it together with the CAN module of the multimedia weaves the CAN communication with the Body computer. After removing both modules everything worked normally.
