I've had an issue where the power window motor in the driver side and passenger side have stopped working. I've replaced both of them and they work. However, I can't control the passenger side window from the driver side door controls. I've tried pushing the buttons down on both doors and pulling them up for certain periods of time and it doesn't work. When I use the button on the driver door, I don't hear any clicks like I do when using the passenger door. Is it possible that I've got a problem with something other than the motor? Could the switch be bad on the driver side? I've reset the switch in the past, so it's not a new concept to me. I just can't get it to work this time.
