That was the first thing I tried...
Then, with the engine off I also noticed that when I depressed the power button on the other 3 windows the dome light dimmed, but when trying the passenger window the dome light did not dim...
I would agree that it could be a switch, but isn't it odd that the passenger window control on the driver's side AND the passenger window control on the passenger side both don't work? Yet the window would go down....very strange...
I'm a computer guy and trouble shoot computer issues all day long, but this has me baffled! And on a week old Edge too...
