I have a 1998 Buick Le Sabre, used it last on Friday (1/14/11) and now on Monday we got some snow by me (4 inches or so) and there's no electric power at all. Remote doesn't work, power windows, interior lights, car won't start, everything. I don't really know much about cars but the battery looked fine, and the battery is only 7 months old. The car has worked fine until now. Any ideas?
