A blade that lifts off the glass, streaks from weak spring tension, or a bent or cracked arm can mean the arm is worn. Before you replace it, rule out a worn blade, a tired wiper motor or loose linkage, since those can leave similar marks on the glass. Arms are normally replaced as a left and right pair.
