Door hinge stop worn out.

I'm trying to stay on top of little things that wear out on my car.

The hinges are fine, what i'm talking about is the spring inside the hinge that holds the door open at a certain point. Mine is busted to the point that the door just swings open all the way with no detents to hold it halfway open. \

hAs this ever happened to anyone before?

How do you fix it?
