Hi traxdog. Welcome to the forum. A common problem is broken or frayed wires between the door hinges but you can rule that out since the other windows work. The next most common possibilities are a defective motor, burned or pitted switch contact, or a cable that has become frayed or broken.
If the problem is with the cable or anything else that is causing the window to bind, a trick to prove the rest of the electrical circuit is ok is to watch the dome light when the engine is not running. If the circuitry is working, the light will dim a tiny little bit when you press the window switch. You have to look very closely to see the slight change in brightness. If there is no change in brightness, suspect the switch or motor. Voltage tests at the the motor's electrical connector will determine if the switch is at fault. Another trick is to switch the two wires to the motor to make it run in the opposite direction. If that makes the window move the other way, suspect the switch. Using a pair of clip leads to connect the wires to the motor is a lot easier and faster than physically pulling the wires out of the connector body and switching their locations.
