Reply To: Need rebuild on my wiper motors


Rainex works exceptionally well on our nearly vertical windshields. The impact of a drop of rain just shatters and at worst leaves a very thin layer of tiny specks or water.  In a light to heavy rain, the windshield is easy to see through.

Regarding the wiper motors themselves, as Jim Chase mentioned the zinc or potmetal motor housing does develop blisters, or twists that prevent the flap or paddle’s sealed edge to fit properly.
