Electric fault left side doors

Hi,

I tried searching the forum for similar faults but did not find anything exactly like my fault.

My 2 doors on the left side have no current running to them. Driver side if the left side on my car. Operating windows doesn't work from the left side, locking the doors with remote doesn't work. Everything on the right side is working. There is no fault with the fuses. The fuses have 12 V against the door metal (grounding). But measuring out at the wires in the door itself gives me 0 V. There is no visible damages on wiring. Yes, I checked under the rubber were the wires leaves the doors over to the rest of the car.

I have no wiring diagram to follow unfortunatly. I guess there must be something common for all the positive wires after the fuses but before the doors. Any idea is appreciated.

Thanks
