Hi, i need some help on my BMW f30 328i xdrive, so basically i had no power in front Passenger door and driver side window was moving inch by inch, i changed wires, whole mechanism and motor on my Passenger side, it came back to life but its too moving inch by inch. I read fault codes and there was 2, both for windows regulator not normalised. Did an initialization but it didn't do the trick, but after i rolled down and up i got 2 more faults with hall sensor, erased codes and the 2 with motor regulator not normalised disappeared. I've been searching internet for any similiar issues but i couldn't find anything like that. Is it possibile that driver side motor is done and the FEM module is blocking signal for both sides? If not what can be the issue here? Im really lost.

Update. Changed motor and mechanism on the driver side. Nothing changed, i just ordered new FEM module. I'll try connecting it and move windows, from what i found in internet fem doesn't need any coding to only test windows. If it doesn't do the trick then im out of ideas.

It's probably the window motor. Did you replace it with chinese junk or OEM parts? It's very rare that an input on a module goes bad. It's usually the input device, or wiring.

I replaced it with OEM part, now im waiting for new FEM to arrive and i'll plug it without coding to just see if the windows were moving like that because something is wrong with my FEM
