UPDATE!!!!
I finally got a chance to look at her car. We found a burnt 30A fuse in the fuse box located in the dash, left side behind the coin tray (wild location for a fuse box). Anyway, it fixed everything but the driver's side window. So, it looks as if the motor, switch or controller on the driver's side must have shorted out and taken the fuse along with it. Now, with new fuse in place, the driver window is dead - but everything else works.
Any hints on how to troubleshoot which window component is bad?
Also, how hard is it to get the door panel off and what's the best source for a replacement part?
