Hello everyone.
So one thing that's happened over the past week or so, the passenger door window, mirror and locking is not working from the drivers side. The window still works using the passenger controls, however there is no auto up/down. The mirror adjustment, folding and heating do not work.

I've checked the door connector, BCU connectors and the connector into the door module and there is no corrosion. I checked the voltage at the door connector on pin 1, there was a constant 12v, no change when operating the drivers door switch. After looking at Rave, I need to check pin 25 on the black center connector on the BCU. I've also checked the fuse for the passenger door module and that is fine.

What should I be seeing in terms of voltage changes at these pins and does anyone have any ideas as to what to check?

Thanks
Qasim

So I got around to having a look today, there was 12V at the car side of the door connector, checked for continuity between pin 23 on the door connector (door side) and pin 1 on the white connector into the door module, there was none. Pulled back the rubber and the p bus wire was intact, after further examination I found a few slits in the wire that had some oxidation. After a little movement, it broke apart into 3 pieces. I soldered another piece in between and its all sorted.

Thank you for your suggestion

Hi, I have the same problem .. I am a novice so could you point me in the right direction to check which connector block you are referring to ?
My passenger door lock was the only original fault, but now the lock/window/ folding mirrror don't work from driver's side, plus courtesy lights!
Thanks
