Power windows/Locks interconnected?
 

2002 Civic 2dr

Several years ago the right side power windows stopped working. I changed out the regulator and motor and it still didn't work. It seemed to have power from the switch.

Sometime after that the power door locks stopped working. I replaced the lock module on the drivers door and not only did the locks work again but the right side window began operating too.

It's been a few years and the window stopped again yesterday. It was slow and jerky going down and stopped halfway down. Against my better sense, I picked up a new motor and regulator again because of the way it was running when it stopped. It still doesn't work and again there seems to be power from the switch.

Can anybody tell me if there is a connection between the power windows and the power door locks? I'm not sure where to go from here. It seems like a pattern.
