On the connector that goes from the rear door switch to the lift motor, you can measure the resistance between the two wires that run to the motor. I don't remember exactly what it is on these motors, but something on the order of 50 or 100 ohms. In any case, it shouldn't be open and it shouldn't be a short.
You can also apply 12V to those wires directly and see if the motor itself is working. One polarity will make the window go up, the other down. If neither works, you probably have a bad motor. If they do work, it's probably a switch problem (either on the rear door or the driver's door).
Did both stop working at the same time?
