What are the reasons for the failure of the Focus wiper not working?

Possible reasons for the wiper not working: 1. Wiper motor damage; 2. Wiper fuse damage; 3. Wiper motor circuit open; 4. Wiper relay damage. Additional information: The power source of the wiper comes from the motor, which is the core of the entire wiper system. The quality requirements for the wiper are quite high. A DC permanent magnet motor is used, and the wiper motor installed on the front windshield is generally integrated with the worm gear mechanical part. The function of the worm gear mechanism is to reduce speed and increase torque, and its output shaft drives the four-bar linkage mechanism, which converts continuous rotational motion into left-right swinging motion.
Last time I went camping in the wild with my Ford Focus, I encountered a heavy rainstorm and the wipers suddenly stopped working, which almost panicked me. After checking, I found that the fuse had blown, located under the left side of the dashboard, and a simple replacement fixed the issue. It might have been caused by an overloaded circuit or dust accumulation recently. Problems with the wiper motor or switch are also common, such as oxidized contacts leading to poor connection. I also noticed that in cold weather, the mechanical linkage can freeze and requires anti-slip treatment. It's recommended to regularly clean the wiper groove to prevent leaves and debris from getting stuck. Safety first—if you encounter a malfunction, slow down and pull over to a safe stop before fixing it. Daily maintenance isn't difficult; doing it yourself saves time and effort while also improving vehicle reliability.
