S320 drivers seat won't adjust

[amosfella]

I was in town today, and wanted to change the position of the driver's seat while I waited, but none of the switches would move the seat one iota in any direction at all... I checked the passenger seat, and it seems that the seat there works. I tried restarting the car, nothing, shutting the car off, taking the key out, and opening the door and adjusting while the door was open. no luck... I pulled the fuses, and all appear to be in good condition.
I recently changed the battery and the horns on the car, as well as doing a brake job....
What would be the next things to check to try to fix this problem??
