Why Won't the Wiper Blades Move?
2 Answers
Here are the common reasons why wiper blades won't move: 1. Power supply issue to the wiper motor, commonly caused by a blown wiper motor fuse, resulting in the wiper's inability to function properly; 2. Damage to the wiper motor itself, either the motor is faulty or the integrated control module is damaged; replace upon confirmation of damage; 3. The mechanical linkage between the wiper motor and the wiper arm is detached, improperly installed, or damaged; 4. The wiper switch itself is damaged or its power grounding circuit is faulty; 5. Issues with the wiper motor wiring, such as open or short circuits in the power or ground lines.
Throughout my many years of driving experience, the issue of windshield wipers not moving is quite common. It's usually caused by a burnt-out or stuck wiper motor, especially after prolonged use or during heavy rainstorms. Another possibility could be a blown fuse protecting the circuit. I always start by checking the fuse box inside the car to see if any circuit breakers have tripped. Sometimes, the linkage mechanism might get stuck due to lack of lubrication, making it immovable. Once, while driving on the highway, my wipers suddenly stopped working, which scared me into pulling over immediately. It turned out to be caused by short-circuiting due to aged wiring. I recommend regularly testing your wipers, keeping them dry to prevent rust. Safety should always come first—never take it lightly to avoid accidents.
