No power going to rear side doors

Hi there. I had a wiring harness installed because of an airbag issue. I noticed the other day my power locks on my two back doors don't work. My mechanic accidently bumped my drivers side rear door...they are getting it fixed at a local body shop. The body shop calls and says they can't roll the windows down.

Is there a common point from where the power goes to the two back side doors?

 

I can't see my two power lock mechanisms and two rear door power window modules going at the same time. As far as I can tell, there is only one fuse for the power door locks and one for the power windows.
