No power to or from all windows??
Just picked up my car from the dealership because they kept asking me for more labor pay and not able to give me any answers or results. Bottom line is I'm getting no power to or from my window ECU or any of the window switches. Sunroof work fine and all of my fuses are good.. Can anybody help??

Where can I find the wiring diagram? All the other windows don't work either, Lexus wanted to charge me $125hr minimum 2 hours to trace the problem.. All fuses are fine and all window motors work with direct power to motors except drivers side. It's a 02 GS430 I'd like to trace the wires back myself and try to figure it out I'm sure it's something simple

Might be the Door ECU, its the black box that controls the regulators, I believe this is in the Driver's Door, you will have to remove the Trim and take a look. But if its bad its kinda hard to test yourself unless you have a wiring diagram. At least you can check for Power at the ECU.
Take a look at Sewell Lexus or look for a used one to test out.

Lexus rested out all door ECU's and window switches already with known working components. There's no power going to or from window ECU's or Window regulators. I need to find another power source before it reaches the drivers door. Fuses are fine so it's something else.. Backwards starting at window switch it goes to door ECU.... Then what's next? And after that? And after that?
Thanks for your help guys

Do they work if you manually go to each door and roll them down using the door switch? If so, you may have to reset them by holding the switch up for like five seconds and pushing the switch down. let me know if this works for you.
