Hello!
So to clarify - you're getting 12V to the window motor, but it's not moving?
Ok - Which window switch did you replace?
Ok, so we know the switches and motor are good from swap testing. If all the wiring an connections are good, I would suspect the up relay to be the failure on this one. I've attached an image below for you to locate it. Try swap testing this with your wife's car and I'm betting this will reslove the problem for you. If you have any other questions, please let me know.
Thanks!
