All locks and windows work properly except the rear driver side. The driver side door will not roll down or unlock that door and the rear door does not operate the window or lock….. What should I start checking first? Maybe just came unplugged?

 

Wiring from body to door.

 

Just be warned that they do NOT sell the door boot separately so if you cut it like I did you have to buy a brand new harness. or do like I did and wrapped it in electrical tape. What happens is the wires snap or tear and you have to reconnect them. I've done butt connectors and have had no problems months after.
