Re: Wiper arm problem.
Have you removed the cover and nut from the spindle. If so, lift the blade up from the screen until it locks facing out from screen. Now with one hand on the spindle and the other grasping the arm about 8" fron spindle gently rock the arm from side to side. This should free the arm which is on a taper.
