Windshield wipers would not turn on?

1997 Chevy Blazer mileage: 79,000. Two days ago when it started raining the wipers would not turn on and the washer motor did not work. Changed the fuse. They still did not work. Next I bought a rebuilt wiper motor. I checked 1 more time before changing and the wipers were working. Does the wiper motor have a circuit breaker that resets itself and is ok to leave it alone or should I go ahead and change it out.
