short electric

I have a 2001 that won't roll down three of the windows. The drivers door gets power but wont roll down any of the other windows or work the locks. We checked the wires on the other doors but are not getting power. The speakers work but nothing else. Can anyone fill me in as to why the other three doors are not getting power. Thanks

Think there is a central 'brain' unit under the drivers seat(on early cars)that control those functions on all but the driver door. Old thread topic.
