do not have any power to any of the windows?

At the window switch do you have power to the yellow power wire? If not, I would check the wiring at the door jamb where the wiring goes through, this is a common place for the wire to break. Here are the wiring diagrams so you can see how the system works. Check out the images (below). Please let us know what happens.

Yes, i have power at the switch but neither one of the front door windows will go down and the back panel windows will not open.

I have checked all the fuses replace the fuse box.

Here is a guide to double check the yellow wire for power and to check the black wire for ground and if so, I would replace the main window switch.
