What is it with my rear wiper? The blade actuates but it cleans only 50% of the arc. As if the blade is straight on a curved glass. A new blade did not help and it seems like thre is planty of tension to press the blade against the glass. Happens in the summer as well as the winter (the summer heat should make the rubber more pliable). The problem seems so simple yet is confounding me.
I can only think tha the arm is not putting enough pressure on the outside tip of the blade so that when it reaches vertical, the tip area loses contact. This would also coincide with the greatest curvature experienced by the blade. I think this is correct so another inspection of the arm is warranted (But it looks good with no hinderances).
