i finally got to move manually my electric drive seat "i own a 2006 hummer h3". No where i found how exactly to do it until i tried and and wow super easy. Probably will take about a hr or two but i doubt it. First remove seat's screws which are foour of them, two in the front and two in the back " then disconnect the wires under the seat towards the back then with the car seat out the vehicle remove the three motors under the seat "you have to remove all three to remove the motor for the seat to go backwards" which is the last one towards the back" once you remove the motors simple twist the middle bar "with one hand or two which ever works out for you" and you will see the seat moving manually backwards or forwards when done simply place the car seat sideways and place back the motors where they belong abd screw back the four long silver screws and place the seat back in the vehicle and screw back the four big screws "that hold the seat" its not hard at all

 

i must be missing something simple, why?

 

That's gotta be a real pain in the A$$ every time you switch drivers.
