Power window and lock issue

I have a 2007 Focus. I bought it and subsequently found that neither the power window motor nor the power lock actuator worked on the right rear door. I've checked both with 12v direct power and they both work fine. Is there a common fuse or feed wire for them? Which fuse? It also has been a salvage vehicle due to collision. I don't know the details of the restoration. Could it be a common ground problem?
Help!! I can use a mulitmeter, just don't know where to check.
