The brown wire gets 12 volts switched onto it in the "down" position but the blue wire must remain grounded. You're showing it with 12 volts. That would be feeding through the motor. If you care to prove it to yourself, unplug the motor and that 12 volts on the blue wire will go away when "down" is pressed.
My guess is the window is all the way up already and at the end of its travel, so you can't tell that the "up" direction works. It's the "down" that is dead because of the switch. As another proof test, hold the switch "down" so that proper 12 volts is on the brown wire, then use a jumper wire to ground the blue wire at either end. If the window goes down, there's a burned or pitted contact in the switch. It is one that makes contact when the button is released.
