A month ago my window on my driver side would not roll up. I disconnected the switches from the door and took the switches apart. I switched the spring and plastic piece from the switch for the driver side window with a switch from the passenger side window. I resembled them to the door and all the windows worked fine for a day. then the driver side window did not want to roll up. So I called the Nissan dealership and they said it could be the switches or the regulator. (I think they said it was the regulator.) Does anyone know what needs to be down to fix mt window?
