man, i have the same damn problem....well, almost...the seat belts seem to work whenever they want to which is too unpredictable for me...sometimes they work as soon as i open the door, sometimes i have to wait for the automatic antenna to go down and other times, it just quits on me.....i'm as lost as you but i'd love to find out why....i'm not sure if this is related but my passenger side window takes forever to go up too....
