The passenger side power window intermittently works no matter which button is used?

I can't trust to get the window back up. Once I banged on door and it came up (some time ago). How can I tell if it needs a new window motor or new switch?

Problem2: passenger door lock switch will not lock all doors. It unlocks them, but I have to go to the driver's door to relock all doors. Again, is this the switch or an actuator problem?
