Hi I have a faulty earth connection for rear door where would be the ground wire in door loom or does anybody have a wiring diagram 2010 s-max?

Door harnesses don't have separate grounds, they run through the door to body connector on the B-Post then ground in the cabin harness.

Check for broken/damaged wires in the main door to body connector

Hi I've checked for broken wires in main door to body connection and none broken also checked two earth point on passenger sill under carpet perfectly fine could it be a faulty door module I have a replacement but it is a year newer

What, exactly, isn't working?

Rear right window and door lock. I've already changed the lock and wiring loom

Swap the module from the LH door, it'll work, but the other way round, or they may even be the same, some are.

If it works it's the module, if it doesn't it's something else

It works turns out door module not working replaced it now working 

But for some reason I have abs and traction lights on solid amber but no fault codes could that be down to moving wires as I took the front passenger seat out lifted carpet to check earth points on sill
