It sounds like the main switch went out. But we should check the PWR WDO circuit breaker, this guide can help:

If the circuit breaker is okay here is how to change the main switch out and I have included the window system wiring diagrams so you can see how the system works.

Check out the images (below). Please let us know how it goes.
