BMW e60 no power to passenger door

[Jrc2002]

Hello, this is my first time posting, so i don’t know if I’m in the right place but, I recently had a friend replace both doors and fender on my passenger side and due to different trims, he had to replace a lot of the leather, trim and other parts of the panel. I got my car back and realized immediately I had no power to my
passenger door. No locks, windows or mirrors. I’ll try cleaning the harness, but it’s a long shot as he already did. I’m not familiar with this sort of thing so any help is much appreciated, thanks!
