The seat motor starts up on the start and stop of the engine. CLicks a few times, before it stops. Can ot see any light on the memory set-button. Can not move the seat back-forward with the door switch.
Driver's side memory seat. on 2003 Lincoln Town Car
It definitely sounds like you have a short or at least a bridged circuit. Really, you need to get a wiring schematic and begin to trace down what is wrong. There are so many things it could be and with out being there, I would just be guessing.
