Door switch?
That switch is in the latch itself. If it's sticking, you can try to spray some wd40 in it, and slam it a couple times to try and free it up.
As for the window switches not working, that sounds more like a broken wire, where the wires go from the door to the body, in that black boot looking thing. You are going to have to inspect the wiring real well.
