Before replacing it try this:
Remove wiper arm assembly from motor shaft. Work the joint/hinge back and forth and lubricate it with some wd40.
Lots of times dirt and grime can get built up in the joint and cause too much resistance for the spring to pull the blade tight against the glass. In your case you may have some snow or ice built up in there. This is a fairly common problem on this type of design of rear wiper blade. I have had to clean mine out a couple of times.
