Thank you for those links and pictures, I'm pretty sure it's the one pointing out with the ballast.View attachment 1715197217

I found a picture of my old wiper motor before I took everything off. And it is the one pointing out with the ballast resistor. And I found another wiper motor, but I have a question? What does the ballast resistor do and where can I get a new one?
