Right around Christmas I noticed that the wiper blade on the drivers side of my car was busted so I bought a new one while shopping in Bemidji New Years Week End. When we got home, I put it on and thought nothing more about it.
A couple days ago my wife told me I should have changed the wiper on the drivers side while I was doing the passenger side because it absolutely did not work. It WAS the drivers side I changed. Apparently, the wiper doesn't like working when you forget to take the protective plastic off of the blade itself. That said, It works great - now.
