Did you test the motors at the motors themselves - meaning you took apart all 4 (or 2) door panels? If there is power at the motor, then the motor is either bad or a ground has failed. Check and double check the ground. All 4 window motors failing at once is rare, but it could happen.

If there is 12 volts at the motor (as you stated) then the switches (and relays) are good. The body control modulator has nothing to do with the power window circuit. How many wires are connected to the motor? Was this vehicle ever in a flood or up to the doors in water?
