Hello, my wiper is kind of glitched. It turns itself in the middle of the of the rear window or anywhere(rarely in the right place) + i can only turn it once, then if i want it once again i have to hold it to release window fluid and then its out until i start my car all over again. I have a smart wiper function but it works only once when i turn on the car. Is it wiring or what? I doubt it is the motor cause wouldnt that be that it doesnt work at all?
