Each drivers door window switch is a DPDT switch, Double Pole, Double Throw. On each of the two poles of the switch there is a NC and NO contact (Normally Closed, Normally Open hence two "throws") When you press the button to open the window the "NO" contacts of the switch close and the "NC"s open. The drivers door switches are the "Masters switches, if the driver operates a window switch none of the other switches can work. The other switches go through the masters and rely on their NC contacts to pass the window motor current.
In a nutshell I believe one of the NC contacts on the drivers door switch for the passenger window has failed. That make any sense?

Yea, bringing back my college courses on me. So if this is the contact is bad the passenger window won't work because the NC contact is no good right?? Hate it cause these things are expensive to replace if I can't get the module apart to try and fix it.
