My passenger window will only roll up from the passenger side switch. It will not roll up or down from the drivers switch. I tested the motor with a battery and it will roll up and down. I also have replaced the drivers and pass door window switches, and it still does the same thing. Any help would be appreciated. Thanks, Craig

 

make sure you have 12V on the green/black(EK) or blue/black(EG) wire.

the passenger's window gets it's ground from the driver's switch, so there has to be connection from the passenger-driver's switches. (both wires)
But the power for the master switch (passenger control) is run from a different wire.

That is provided you have a factory power window setup, anything aftermarket or "tampered" with, you'll have to get in there and troubleshoot.
