This might seem overly simple but , can you get to the harness that goes to the seat ?

Can you find the motor ? , if so take the two wires that go to the motor and use +12V on them to see which way it moves, if int he wrong direction reverse the wires and move where you need to.

I helped a buddy recently with a Window that would no roll up in his 7 series BMW, we simply unplugged the harness going to the motor and applied 12v directly to the motor to get the window up.....I used a small gel-cell battery like you see in emergency lights or a childs electric car to do this.
