Today I lubricated it with no positive result. It would move the shaft, but when the resistance of the arm and blade was added, it only goes halfway across the glass and stops I have nothing to lose . Tomorrow I will take it apart. You and Richard have given me the confidence. I may have to buy a case of Rain x I am also troubled by a fair amount of air noise from the control valve/switch, but that can be another day.
