Why Won't the Windshield Wipers Move?
3 Answers
Windshield wipers not moving is usually caused by a blown fuse (which prevents circuit overload). In this case, you need to open the fuse box and check it. Windshield wipers are tools on the front glass of motor vehicles designed to simply clean rainwater and other debris that may obstruct vision. The key to the effective functioning of windshield wipers is the rubber wiper blade maintaining sufficient moisture. Only with adequate moisture can it maintain excellent flexibility, ensuring tight contact with the car window glass. The term 'fuse' is a conventional name; in national standards, it is referred to as a circuit breaker. The function of a fuse is to protect the circuit (wiring) and electrical equipment.
Last time I was driving in the rain, the wipers stopped working, which gave me a scare. I quickly pulled over—safety first. Experience tells me that common causes include a blown fuse, motor failure, or the wiper arm getting stuck. Fuse issues are the most frequent; check the fuse box under the hood, locate the wiper fuse, and replace it if it's blown. If you hear a humming sound when starting but the wipers don’t move, the motor coil might be burned out. Wiper blades stuck by leaves or frost can also cause failure—try cleaning them. Additionally, don’t overlook switch damage or poor wire contact. Such issues are dangerous in the rain, impairing visibility and increasing accident risks. Regular maintenance is recommended to minimize faults.
When I find the wipers not moving, I first check the fuse box to see if the wiper fuse is blown—replace it if it's black. If there's no sound or movement, the motor might be faulty or the wiper linkage could be rusted stiff—especially common in rainy weather, so lubricate the linkage joints. If the wiper arm is frozen or jammed with debris, cleaning it should solve the issue. Switch failure is rare, but pushing it a few times might restore function. For electrical issues, use a multimeter to test for power, but if simple troubleshooting doesn't work, take it to a repair shop. Keeping the wiper blades clean and the windshield clear helps prevent such problems.
