I was reinstalling my passenger side door panel on my 2004 350z and I pinched the wire harness causing the wires to make a cross connection. The window instantly went down. Ever since I replaced both the window motor and the entire harness for that side and I still have no control of my window. It won't go up nor down.

 

Check fuses

 

I took a circuit tester to all three fuse boxes and they are all good. There's no designated fuse for the passenger side window as far as I know.

 

Try resetting the window motor. Search the forums for the procedure..

 

double check the window lockout on the drivers side

 

All great suggestions but none have worked.
