Electric window & mirror issues

Sorry if this has been covered but think this is not quite what others have had.

So drivers switch works for all windows, the passenger or rear drivers side will not work from the switch.

However,

I have moved the working switch from the other rear door (that works by it self) to try on the passenger and other rear door that don't work from their own switch. Neither of these work with the confirmed working switch, but also both switches work in the fully working door. So from that all switches are fine?

The electric adjustable mirror also do not work either wide.

Didnt get any errors with standard obd2 but I think I got a vag scanner somewhere.

Is this likely to be broken wire to the switch (as the drivers control works all of them) or is this a bcm issue?

I checked the drivers door and there were some old dodgy connections to the wing mirror which I redone properly.

Are there separate door control modules too?
(all fuses are OK)

Appreciate the help.
