I had the same problem with now power to windows, mirrors and seat. The common soulution is the orange and or black wire in the boot have broken between the door and post.

SOURCE: Rear window on driver's side slides down

I've had this problem and I believe its a common problem with S types. There is a white plastic slider that wraps around a metal strut and moves up and down as the window opens and closes. The problem is that the plastic slider breaks if the car door is slammed when the window is half way down, When this occurs the slider breaks free and the wire that pulls it up and down wraps itself around the motor and jamms everything up. The fix is to replace the window regulator as a complete unit. This fairly straight forward and worth the effort as you most likely will be replacing the other regulators if you keep the car for a while. Buy the regulator either from Jag dealer or OEM part which is approx 1/2 the cost (I found mine on ebay!). Make sure your get the correct unit, left, right, front and rear are different. Take off the door panel, its all clips except you need to unscrew the two scews under the rubber insert in the door pocket first. After you have removed the panel remove the black plastic cover as well. You need to detach the glass window from the regulator, This is done by punching out the brass insert in the middle of the plastic plug that is pushed through a hole in the glass. Be careful, if you hit it too hard you can break the glass, I ended up drilling it out as this was easier. Once you have the plastic plug out the glass is detached and you can remove the regulator. This is just a few screws, the only tricky part is to get the angle right to pull it out the door frame. Installation of the regulator is just the reverse. Good luck.

I had the same problem on the rear door of my 1998 528i and it was the door actuator that had gone bad. I had to take the rear seat out to get the door panel off. Once I had the door panel off it was not that difficult to replace the door actuator.

It sounds like the linkage connecting the door handle to the latch has disengaged....you'll need to remove screws that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. You'll need to lift the door panel upwards in order to get it off the window ledge. You can then pull off the weather seal in order to see the inside of the door....
