Hello. I`ll stick to the topic, when my wife was driving a new Passat, she had it for 5 days, suddenly her windshield wipers stopped working on the highway... sleet at night... The girl stopped on the highway, didn`t know what to do, turned on the hazard lights, didn`t she opened the hood, tried to turn the car off and on, hoping that the problem would go away. She panicked and started moving the wipers and they started working... it`s terrible... the problem occurs randomly! Not permanently!! So there must be something wrong with the contacts, I have to fix it, because this is not a joke. I will try contacts, connectors, everything you wrote.
