I'm assuming Driver Door works? Used to happen alot, even on the new cars. Make a jumper and connect to the switch, see if it works now. If switch and motor good, then most likely it's in the wire coming from the body and into the door. The wire breaks after repeated opening and closing of the door. Does the door speaker work and no static? Any recent work under or behind dash, such as HVAC or radio work? You will have to trace starting at the relay. Assuming driver door no issues... Then it's not the power relay or fuse, the issue will localize in pass door. If driver door also not working, then check power relay and circuit to and from relay. Always check grounds as well. Connectors get rusty and then circuits fail.
