i'd love to say you were, but i think mine is slightly different...
correct me if i'm wrong, but my seatbelt works 100% of the time, it just gets stuck once it's in the all the way down position. it moves about an inch up when i open my door, and once i wiggle it "free" it opens all the way. e.g., if i close my door, and open it right before it latches, it'll go all the way back up. so i don't now. i read that other post to see if it was the same thing. if that's the solution for mine though, i'll take it.
