Managed to get the passenger window working again by switching all the window switches for second hand BX switches. Minor victory

Also put some WD40 in the motor and friction parts while I was at it since I read elsewhere on this forum that people had success with that and so far it seems indeed to smoothen things up a bit.
New problem arose though. There seems to be no power on the switch on the passenger side now. A bit mysterious because there definitely was power on that a few days ago when I disassembled it to find the problem. Any hints where I should look?
The passenger side window switch on the driver side works the way it should by the way.
If you check out my FAQ (where it is fully described) and the wiring diagram, as I've said many times, BOTH window switches for the passenger door window have to work fully for the passenger window to work as they are linked. So first step is always to make sure ALL window switches function correctly.
So for instance there is no earth to the passenger door - the earth is via the drivers door switch. Also you will see that the power for the drivers door window switch is 3B whilst that for the passenger door is 3A. Trace those back to the circuit board and you will see they come from different terminals. This is why you always need to refer to a wiring diagram.
The switches themselves are quite common and easy to get, but not all switches are internally wired the same so you need to be careful. However the Citroën switches are probably the same as PSA would be using the same supplier.
