Does anyone know how to adjust the rear wiper blade so that it will actually wipe the glass? The motor and arm are both moving fine. New blade and blade sits on glass when off. When I turn the rear blade on everything works except the wiper blade moves just off the glass and wipes air!

im not sure but the only thing i could think of is that you may have baught a blade that is too long and when it starts moving and the angle changes it hits the arm and comes off the glass. i have no idea if im right or what im saying makes any sense at all but i thought id try

wiper arm nut may not be tight, arm nut fully seated on shaft, arm could be bent or debris in hinge of arm not allowing blade to contact glass, or spring on arm that pulls arm towards glass is weak,broken or missing.
