how about a bad switch ? what you could do is put a voltmeter on the wires at the motor and check but I guess that you have nothing otherwise at least one window would shut ? I guess both motors would not die at the same time? If you get stuck with them open and it going to rain then apply 12 volts to them to force them shut ,I guess it just reverses the polarity for open and close I don't know ? If the motor has only 2 wires then what I said is true and if the motor has 3 wires then you will have to figure out what pair to use it would be nice if someone had a service manual or diagram . Good luck and keep us posted to keep these vans on the road.
