The memory module might be looking for inputs from another computer that it's not seeing. You might want to start with finding another power seat without that option and swapping the wiring harnesses to get rid of it. If all the seat movements aren't moving it's probably something more then the motor part. When those go bad you loose forward/back or one of the up/down things not everything.
I'm looking for a non memory harnes and switch. I'm concerned that it's looking for inputs it's not going to get. I just don't know enough about how it works.
