There should be a lockout button on the driver's door. The other three window circuits go through that switch. Also, each of the three passenger windows has two wires that go through their corresponding switch in the driver's control panel. One is for 12 volt power and one is the ground. Their functions are reversed by either switch to change the direction that motor goes.
Every window switch has two switches built into it. When a button is pressed, one switch stays released and one turns on. Current flows through the lockout switch, through both released switch sections in one switch, through the activated switch section and the released switch section in the other switch, the motor and wires, then to ground and back to the battery. To say it a different way, current has to flow through both window switches twice, regardless of which switch is activated. If the power wire feeding the passenger doors is broken the windows will only work from the driver's door, not from the passenger switches. If that power wire is broken where it goes to the driver's switch assembly, none of the windows will work.
