| Spent some time searching for someone here that has had a similar problem...found some good info, but still can't figure out the reason my passenger window will not go up. - passenger window lock is not engaged - driver's side passenger window switch will not raise the passenger window. Passenger window switch will not raise the passenger window. - passenger window will go up if I switch the wiring around and cause the window motor to spin the opposite way when pressing down on the passenger or driver's window switch. - passenger window receives +12V and -12V when the switch is operated without the motor attached, bought a new switch anyway - the old switch looked old! - passenger window motor operates fine (both ways) when plugged into the driver's side window motor connector - found the small box near the bottom center of the driver's side door. When unplugged, the passenger window will go down, but not up. The driver's window will not operate. - do not have a blown fuse I guess this just leaves a wiring problem somewhere after the driver's side switch and before the passenger window switch. Unless, the small box that I found is bad. Anyway to test the box? Thanks!
