Nearly identical problem, will post if I learn more mysdelf!
Hi there, I have a nearly identical car, and I have nearly identical problems. What I discovered is that some of my windows aren't getting any power at all, then I went to the switches, and poked around. What I found (by swapping switches) is that all my switches were functional (all the switches are in effect capable of opperating the working window (driver side rear)). That pointed to me that the switches weren't even getting power. Unfortunately there is one fuse that keeps blowing, but a previous owner has lost the fuse diagram, so I don't know what it opperates.
Now with the winter comming this is no longer as much of a priority as it once seemed (summer) but I would love to hear from you if you have made any progress on your windows and what you discovered. As soon as I get something I will post it for all to see, it's just that for now I haven't got any news yet! (Guess I'll post this anyway)
Hope to hear!
