I think Jeff's problem is that those items don't work when the key is in the on position. That's definitely not normal.
There might be a problem in the power separation relay (code E?) that decides whether the seats and windows get power because a door is open or because the key is on. I believe that relay is in the main fuse box. In a US car I believe it's the relay along the passenger side edge of the fuse box second from the front. So two rows of fuses, one relay, then the power separation relay.
This might help identify the relay -- have someone open and close the driver's door as you feel which relay clicks. Hopefully one and only one clicks.
Hope that helps.
