Ok, your still not being clear. Try all this first. Go out to your car and get in the driver seat.
1) Does the seat move back and fourth using the controls on the side of the seat? Yes? Read on, No? Probably a fuse, go to the dealer and have them fix it for you, or open the owners manual and locate the fuse and replace it yourself.
2) Yes? the seat does move? Now hit your memory 1 button. Does the seat return to the saved position now? Yes, Keep reading, No? You just need to set the memory using the steps provided in your owners manual, or take it back to your dealer and have them do it for you.
3) Yes? It did return to the starting position, then your done, it's saved, and you didn't have a problem. :)
