What are the reasons for the wiper not moving?

Reasons for the wiper not moving: 1. Fuse blown; 2. Motor burned out; 3. Wiper switch failure. The wiper is a tool installed on the front windshield of motor vehicles to perform simple cleaning to prevent rainwater and other debris from obstructing the view. The power source of the wiper comes from the motor, which is the core of the entire wiper system. The wiper uses a DC permanent magnet motor. 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. The output shaft drives the four-bar linkage mechanism, which converts continuous rotational motion into left-right oscillating motion.
When I first encountered the issue of the wipers not working, I hastily checked my car. Recalling that heavy rain day when the wipers suddenly stopped, I had to pull over. Flipping through the manual, I found the most common cause is a blown fuse – it protects the circuit and cuts off when overloaded. It could also be a faulty wiper motor, the component that drives the wipers back and forth. Or, the wiper arms might be jammed; if debris like leaves gets stuck in the linkage, the motor can't push them. Aging wires or loose connections might also prevent power from reaching the wipers. Additionally, a faulty switch could stop the signal from being transmitted. That time, I learned to pull out the wiper fuse from the fuse box and try a spare – replacing it fixed the issue immediately. But some problems, like a damaged motor, are too technical and require a mechanic. Regular checks of the wiper system before the rainy season are crucial to avoid trouble on wet days.
