Why is the passenger rear window motor always energized?

The motor always has 12 volts on it except when I remove the up and down switch on that door. Is the switch bad or the switch on the drivers door? a relay?

    When I checked the motor for the window it was burning hot. I verified it had 12 volts going to it all the time. When I remove the window switch on that door it removed the voltage. The gear box is not frozen, the window will move properly. Why is there voltage all the time? Window switch have a relay that's stuck?

    Depending on the model and year of your car the windows are either directly controlled by the switch or there could be a module involved. Since you said when you remove the switch the power went away its likely this is just a bad switch. The switch applies the ground circuit all of the time on both pins at rest, and then it opens the ground circuit and applies power to that pin it when being activated.
