Found a problem. I diving in to check the harness and found a few cuts. Noting went through, but some monkey had a blade in that part of the kick panel. I also found two grey wires. One solid grey, one grey with black dashes. These where clean cut and also went up into the door. Reconnected, but no clue what they are for. Thinking heated mirror.

But clearly there was not major issue there. But it may have been the result of what I found. I too the seat "computer" out from under it. I opened it up and found a small copper lead had fried. I installed a jumper wire and put it back together.

For a brief moment there was the sound of trumpets as the seat, for the first time, rolled forward on command. Well, until plumes of smoke came from the computer followed by an abrupt halt of the seat. Now it does nothing at all. At least its no longer fighting itself in that endless loop issue. And yes, its now disconnected. I will take the computer out again and see what I can find now. I will put the seat back in and be on the look-out for a new seat controller.
