Yeah, the shinier rectangle shaped device is a auto-resetting circuit breaker. There's nothing for a human to reset. It does it on it's own. That's why I said earlier that it might have been forced into a loop of tripping and resetting, over and over and over again. That might be the noise you hear. Why is it doing that? The circuit is overloaded for some reason. Much like when a breaker trips in your residential panel, only those do have to be reset manually when they trip. Why did it overload? Might be that the wiper motor has locked up for whatever reason like the other guy mentioned. You'll need to check into it.
