Are there any members out there that have knowledge on how to adjust the rear wiper arm to clean/clear window completely. I took advice from other members and payed $20.00 for a FACTORY rear wiper blade. It clears identical to the one I replaced. My wiper only clears the upper most portion of the window. My question is short of replacing the wiper arm with a new 07 style arm, Can I adjust the arm so it "pushes" against the window more. This would help because while the wiper is on I push slightly on the arm while it's in motion and I get a perfect, complete sweep. Any info would be greatly appreciated.
