Summit Benz

So I have a faulty driver power seat switch or motor. The switch that lowers and raises the entire seat does not work. I do not have any type of wiring diagram to figure out what wires go where but the relay in the switch does click so I'm not too sure what component is faulty.

The long and short of it all is I really don't care if works I just need to lower the seat it is set up too high for me. So can I somehow manually lower it by hand? I was thinking unplugging / powering down the motor to manually turn the seat bars downward?? Would this work.
