Now none of my window switches work on any door. What should I do with this in my 90 suburban.

You could start with checking the fuses

They are powered by circuit breakers (little silver blocks) remove your door boot and check for broken wires in drivers door. That was a very common area for wires to break.

They started by working on and off if that helps?

Sounds like a bad circuit breaker. Find the one for the window circuit and try a new one.
