Power seat movement ... slow, intermittent.

If the drivers seat can't be adjusted so the driver can reach the pedals etc then it's a fail point. It's possible if a similar rule exists where you are that this is why the car was in the yard and you struck unlucky with it.

That aside, the symptoms you suggest point to a fault in the ECU - the big flat box underneath the seat. If you (or someone you know) knows about electronics, it might pay to have a look inside for dry joints.

Just read your latest post about going for another seat - that might be the answer. If it works, you can swap the cushions and/or covers to get the colour scheme you want/need so colour isn't important.

I didn't bring a battery to test it. I'm learning

I will look at the ECU again before starting the job of tearing down / swapping parts to the manual seat. I am leaning, however, to just going ahead and going straight manual if the parts are swappable.

I'd like to swap:

1. Full seat back from the powered to the manual, as the lumbar in the manual I have is faulty and I'll need to swap the foam and cover anyway. (can I convert the power driven seat back position to using the handle?)

2. Move the foam and leather from the power seat bottom to the manual seat bottom.

3. I will test the heater in the seat bottom and probably just leave the heater cables and springs there. They look decent.
