In my 05 Grand Prix GT, the front up and down adjustment on my power seats seems to be stuck. I can kind of see under the seat, and when I hit the "button" up or down, the little shaft that rotates normally (from what I observed on the rear adjustment) is stuck and kinda just wrenches the thing securing it around a bit.
I honestly have no clue how these seats work so I'm not sure where I should start. Clearly the motor works, so something is stuck or broken and in a bad place.
