windshield wiper motor intermittent


Topic starter
I have a 1987 Caddilac Brougham D'Elegance, with ~150,000 miles and is automatic xmission. My windshield wipers stop working only during heavy rains, and start working when the weather dries out ... usually overnight. Any thoughts?

Well, if it only does it in heavy rains, I would guess that the wiring is corroded somewhere The rain gets there and shorts it out and then when it stops raining hard it dries up in a connection works. That's the only thing that would make sense if it works fine on their light rain. But of course it could be the whole motorist assembly that it gets wet and it shorts out internally to it. Might not just be the connection. It could be the whole motor assembly because the motor assembly has all kinds of wiring and circuits in them. That could also get wet and short out
