What Causes the Windshield Wiper to Stop Moving Completely?
2 Answers
The reasons for a windshield wiper not moving at all include: dislocated transmission linkage, blown fuse, burnt-out motor, and obstruction by debris. If the wiper has minor issues, it might be due to loose screws on the wiper assembly, which can be fixed by checking and tightening the screws promptly. Additionally, if sand or mud is stuck around the wiper preventing it from moving, gently shaking it a few times by hand may resolve the issue. Dislocated transmission linkage: This could occur if the linkage is incorrectly connected to the wiper arm. Some arms are secured to the linkage with screws, which might be locked in place, preventing movement. Blown fuse: Open the fuse box and check if the corresponding fuse (refer to the manual on the fuse box cover for specifics) is blown. If so, simply replace it, but remember to turn off all electrical systems in the vehicle before replacement. Burnt-out motor: During testing, pay attention to any unusual noises from the motor. A critical sign is when the wiper motor emits a "humming" sound but fails to rotate, indicating rust or obstruction in the mechanical transmission parts. In such cases, immediately turn off the wiper switch to prevent motor burnout.
I've been driving for over a decade and encountered non-functioning wipers several times. It's usually caused by a faulty motor or blown fuse. Last week when the problem occurred again with completely unresponsive wipers, I immediately pulled over to inspect. After opening the fuse box, I found the corresponding wiper fuse had melted – replacing it with a spare fixed the issue immediately. With motor problems, you'll typically hear strange noises or complete silence; loose wiring connections are also common and just need re-seating. Sometimes wiper arms get jammed by leaves which simple cleaning can resolve. I recommend checking the wiper system during every car wash and lubricating the joints to prevent rust. Safe driving depends on clear visibility, so never ignore non-working wipers – get them repaired promptly.
