There is a problem with the internal switches. That is why they only stop when the fuse is out or the switches work intermittently. I would say a new motor is needed or you can dismantle the wiper motor and try and fix the problem, you would see how they work anyway, quite clever and simple.
If I remember correctly there was a long court case in the '60s or '70s when the inventor figured his idea had been stolen from him, he won and got millions.
See what I mean 🤗 I told you he would know.
