Power window passenger side motor moves one direction only

Thanks for your answer and information. I disassembled the passenger door. Connections and pins looked good. I took away the motor itself, but I could not find anything wrong. Took out the switch box, opened it (is that the module you are talking about?). Green circuitry looked good. Interestingly, a tiny pink wire was coming out and going nowhere, literally hanging. Lights does not dime when up switch is operated, from both the passenger and driver side. I assume motor must be good, as it moves in one direction, and so it must be able to move backwards if appropriately commanded.
I would like to avoid buying a switch box for nothing (new is $330.00).

Hello. Thanks. So, I ran a test on the cable that than is connected to the green cable that goes to the motor (electricity come so from the switch box). One of the pins is hot when switch down, cold when up. The other is cold all the way, switch up or down on passenger side.

Hello, thanks. It comes from the switch box on passenger side. However, up command does not work from driver side as well. By module you mean the passenger side switch box?

Thanks so much. Both driver's and passenger's side up commands are faulting. How can I know which one I have to replace? I guess replace because I am not sure it can be repaired, is it not?

Thank you. Would you replace can passenger or driver side (or both)? Also, would you know what is that funny pink wire coming out of the switch box? It goes nowhere, attached with tape to the door plastic.

Okay thanks. So I should replace passenger side switch box?

Are they independent or interdependent? Maybe I am missing something: in the diagram you provided there is no command for passenger window in driver module. However, drivers module has a command for passenger window. However, motor is connected just to the passenger side, meaning, I believe, that command from driver side goes to passenger side switch and than from it to the motor. Is my reasoning correct?

Thanks. As I can hear a tiny little click when driver switch for passenger up window is operated, I am crossing the finger and assume that the passenger module is faulting, replace it and let you know how it goes.

Thank you so much.

Hey, look at that.
