I have the vehicle listed above and I don't have any power to any of the windows and the 30-amp braker has power to it.

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.

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.

Here is the quarter window wiring as well which is powered by the same yellow wire and how to replace the window switch. Check out the images (below). Please let us know what happens.
