I had a spare NIB window switch. So I popped out the pax door one and replaced with the new spare. No change. So then I popped out the driver door one and voila, one of the wires had come undone. Plugged it back in and everything worked.

Thanks to your reminder that the switches are looped, I tried just swapping out the switches in the hope of finding a faulty one. Even better, they weren't faulty--just disconnected. Though how that happens inside the door is a mystery to me.
