Passenger Power Window Doesn't Work

The passenger power window has stopped working on my 2000 SR5. It won't work from the driver switch or passenger switch. I read an older thread that the guy replaced the relay it fixed the problem, but both of his windows were out, so what would cause only my passenger window being out?

 

is it locked from the drivers side?

 

mine did that,turned out I hit the small button by the passenger window button on the drivers door.it stops the passenger window from working,I think it's a kid safety thing.

later tig1

 

I don't have locks for the windows

 

it could be a few things causing that. like the master switch could be bad which thats the drivers window switch, if thats bad you cant control the window from both doors. or the passenger window regulator motor.
