Sorry, I should have mentioned that all of this circuitry is underneath the carpet. My control runs along the door side rail of the passenger seat on the floor under the carpet, and there is a red wire plus a multitude of other wires leading from the power window control unit that lead out to where the passengers feet would rest under the carpet. That is where my "connection" was, and also the source of my problem. I'm not sure if not having a switch in the back passenger side window would cause a problem. At least on mine, all of the windows were grounded through the main drivers side control and that in turn ran a ground wire back to the control unit and from there was grounded to the car. If the drivers side windows are working, I would assume that ground is good, although maybe I'm wrong.

OK, I went through this about two months ago with my 92 Loyale, and your system sounds just like mine. Basically, out of the relay switch comes one common red hot wire that feeds juice to all of your windows. In my car, it traveled about 18 inches and was only really taped to the other four wires goig to each of the individual windows. That connection in mine had corroded away and I lost one window, then another, then all of them. I replaced the wire, and put in a better connection system and all works to this day. My relay, control box and power supply was all situated under the passenger seat and the red wire ran under the rug, so removal of the passenger seat was necessary. I'm not sure if this is the way it works on your car, but hopefully it may help.
