I had a broken wire between drivers and passengers, have the same problem. Mine was broken just where the lookin goes into the drivers door. Very difficult to find, I just re wired it from one switch to the other.
You need to take both for cards off and get a multimeter in there and continuity test the wires, it was a year ago so can't remember where I got the wiring diagram, but the wrote which links both switches had no continuity
Other than that yeah there is a passenger windows lock button
