Make sure you try the switches on the rear doors as well as on the driver's door. If the rear switches work but not the driver's switches then you either have a driver's switch problem or the wiring near those switches has gone bad.

If none of the switches work then I would be suspect of the wiring if they died at the same time. It *could* be both of the motors are fried or seized, but it seems unlikely that this happened at the same time. In any event, if none of the switches activates the rear windows, you are probably looking at taking off the rear door panels and checking for power at the motor with a multimeter. If you have power you can try banging on the motors a little but you would probably need new ones.
