This happened to me about 6 months ago. First it would just lose electrical for a few seconds then regain electrical, when electrical came back wipers would cycle, spedo what cycle like it does when you start it and that would be it. It gradually got worse to the point it would do it non-stop which would mean the wipers would run continuously, and I had zero electrical while driving. I did a little research and decided to pull the gauge cluster and I unpluged the 2 connectors and reseated them. I havent (knock on wood) had a problem since.
