I have a leak into the door, running down where the front driver door hinge is. It will freeze, obviously in the cold. Do I have to replace the whole door seal? Any other ideas?

 

If the strip is damaged, go ahead and replace it. But I just looked at mine, and that is where the strip drains the water to. So I doubt it will help. The water can just go through the seam between the fender and door anyway.
