both sides stopped working,fuses not blown,how do i find wiring diagram(don't have a manual), how do i fix it

check the feed to the switches. Fronteras are problematic with electrics but with a meter just keep going until you find the problem. Once fixed be careful of the windows coming loose of the regulator. This happened on mine and fouled the door opening mechanism resulting in the door swinging open as I turned a corner!
