My passenger side windshield wiper hangs up about 4 inches above where it is supposed to lodge when not in use. While this hurts nothing, I'd like to get it to go down to its proper place. Do I have to replace the darn thing or is there an adjust I can make to correct this????

 

You can adjust the placement of the arm. Remove the retaining nut and pull the arm off. Reposition it on the splined shaft and reinstall the retaining nut.
