Technical Tipo locking windows stopped working

[Sisu537]

Hello! i have a factory optioned Late tipo that has self closing windows when you lock the car but my passenger side stopped working. i dont understand wiring much so i would appreciate if anybody could tell whats wrong. The window itself works from interior buttons normally but doesnt self closed when locked, it used to close itself halfway then completely when i lock it again and it just doesnt do it anymore. Genius is the brand that has made this module

Hello,

I'm 100% sure it uses the same mechanism as if you use the interior button. If it starts to close the passenger window, the electric module should also be the same.

What happens when you close the driver side window before you leave the car (with the button) and then use the module to close only the passenger window?

Might be that the battery is too weak. Can you connect a multimeter to the battery terminals and observe the voltage when the windows are closing? What are the readings?
