Renault fluence 2011. 1.6 16v.
The customer bought car with non working rear windows.
I don't have any wiring diagram for this car and couldn't find any good.

I found that the problem is that there is no voltage on one wire (acc). Also found that front windows are with auto open/close, rear are simple.
All fuse diagrams I could find say that there should be 2 25A fuses for rl and rr window but it can't be - has to be only one.
All fuses are ok, all wires from doors also.
Tried to trace wire, but it is real PITA.
When I connect 12V on that wire, rear windows work. I can fix it this way, but I want to find what is the problem. So, if someone has wiring diagram or some idea, please help.
