At this point, either we lost power from a fusible link in the under-hood fuse box, the window relay has failed, or the main driver's side switch has failed.
Here is how it works. Power is sent from the fusible link to the window relay. When the key is on, the relay circuit is closed, and power goes to the main switch. From there, it is distributed to all other windows.
I attached the wiring schematic below (pics 1 and 2) for you to review.
The first thing to do is check the 40-amp fusible link in the under-hood fuse box. See pic 3. If the fuse is good and there is power to and from it, remove the main switch in the driver's door. Locate the purple wire going to the switch. With the key on, see if there is power to that wire.
If there is, my first suspect is the main switch. If there is no power, we need to work backward to determine where it's lost. Additionally, if the fuse failed, replace it and see if it happens again. I have a feeling the problem is in the switch and it will cause the fuse to fail. Something was happening before you lost total power which may have caused the fusible link to fail.
