Hi,

Like many others, I was affected by broken cables in the wiring harness in the driver's door.

It appeared that the windows, electric mirrors, etc. stopped working.

I reparied the cables that were broken, but after this the central locking stopped working. The central locking worked before i repaired the cable.

Unable to unlock either with the button on the key, the button in the car or with the key in the door.

Any tips?

Can't find a fuse for the lock?

Reg or VIN please, to find build date and thus the best circuit info.

Any chance you crossed over some same or similar-coloured wires when repairing loom?

VIN : TMBEM65J1D3155191

I think I got all wires right, evything that didn't work before is now working.

Will dig out wiring info tomorrow for you. 🙂

This diagram shows the wiring associated with driver's door lock (F220), particularly (highlighted inside purple rectangle) their pin numbering at the 28-way A-pillar connector.

This should facilitate testing for continuity and short-circuits. The brown wire coming from lock module to pin 23 appears to be a candidate that would disable both lock motors if it were not intact.

Is it possible that the 28 way connector proved difficult to refit (poor access, locking lever not fully open, etc.) and pin 23 of the male connector in the A-pillar is bent or damaged?

Phone camera may be handy to be able to see where the head can't be.

Thanks!

I need to find some time to troubleshoot (and understand the drawing fully 🙂)
