Replace Power Window Regulator on 1999 Toyota Sienna

The power window broke on our 1999 Sienna minivan. Here is how I debugged and fixed it. Had to remove the door panel, figure out whether the problem was the switch or the motor, then remove and replace the entire regulator assembly. I believe that Siennas from 1998 to 2003 all have the same door, but no guarantees.
