Apparently my search foo skills are weak but found a few threads but not much. I took the seat out, the side with the motor works fine. The other side doesnt move. The cap is missing on this side and the shaft pushes in and turns when I hold it with my finger but the screw drive doesnt move. I am assume the gear is stripped and I need to order one and a cap like this seat parts ? Anyone know of a thread that walks you thru it ? I appreciate any help you could provide.
