Hello, I did bodywork on my truck listed above four doors, 1500 HD. I had to take all 4 doors off my truck and now I have installed them back on. When I did that, I could control my front driver side and back passenger side window from the switch controller on the driver's side that should control all the windows. But I could control the other windows by using the switch on the door. Now I have lost control of the passenger back window and the switches on the other doors do not work. Now I only can control the driver's side window, and only lower the back passenger side window, but can't roll it back up. How do I fix this, and do you possibly have a wiring diagram for this truck?

It sounds like one of the grounds is not connected or you have a window relay that is not working.

Here is a guide to help you test the wiring and the 4 door window wiring diagrams.

I found that I didn't connect a line that came through the hole where the electrical wires came through from the door into the cab. It was hung up inside the door grommet. It had the two power lines.
