After that, you have to turn the ignition to the ON position to get them to move, if you don't want to close, and then re-open the door.
This is the behavior on Bat's '08 Convertible.
BC.
Not on my car I have found out, mine do not time out at the same time as the interior lights do if you leave a car door open. The interior lights are controlled by the BCM, the seat solenoid is not.
If they are properly working the seats can be adjusted any time, ignition on or off, doors open or closed.
If they only work when the doors are open then the diode indicated in the photo below has failed.
If they only work when the doors are closed then I would hazard a guess that the diode laying alongside the diode indicated in the photo below has failed.
The diodes cost $1 for ten, the relay costs $15 to $20 plus. You have to tear out the trim either way.
The Relay part number is;
MB #002 542 22 19
Siemens Part #72KD305
and mystery numbers, PA6-GF30 and A430303
The diode part number is SM4007 - SM means surface mount.
I replaced mine with part number 4007 - these come with a wire at each end.
I bent the wires and soldered them to the board keeping the diode flush with the board so that it still fit inside the relay housing.
Seat relay removed from housing.
Trim removed to expose seat relay.

Reason: Found out I was in error on seat time out.
