Yup. In all the cars I've worked on power windows and windshield wipers use thermal circuit breakers that reset automatically when they cool down. That usually takes just a few seconds. That's a safety feature that gets those systems working again if possible. If there was an intermittent short, a blown fuse would cause a total loss of function. A circuit breaker that resets by itself, even for a few seconds, can provide just enough operation to get the job done.
Circuit breakers can fail too but that is not real common. There will be an arc each time the contacts open, just like with a switch, and eventually the contacts will burn away. That doesn't happen very often with a circuit breaker because the contacts don't open very often so little arcing takes place.
