Power Window problems on my 84

[CN84C10]

OK, heres the deal. I'm a newbie, you can tell by my small number of posts. I bought this 84 C10 that had been sitting in a body shop for the last 2 years. An overall paintjob was done and everything was still apart. I had to put the doors back on, have glass installed etc. Once I got the doors together the power windows weren't working. So I diagnosed the driver side as a bad motor(The motor would run, but the gear would not move) So I replaced that along with the belt molding and the run channel which by the way was all in brand new GM packaging behind the seat I then noticed that someone had plugged the power lock connector to the window motor on the passenger side which seemed like a quick fix. After that problem was fixed the window went down, Once and never would go back up. I assume its a bad motor and I put a new one in. well, same problem, window would move down, but not up.(Driver and Pass switches) I got frustrated and left it alone for awhile. I come back to it later, and the damn window goes up once, and now will not go down. Does anyone have a Schematic so I can try to see how this system works? when the switch is pushed either way, both wires going to the motor have 12V, It seems to me that this should swap power from down to up Correct? Any insight on this would be greatly appreciated.

Thanks
