Why Won't the Car Wiper Stop Working?

[AlainaMarie]

Car wipers that won't stop may be caused by damaged wiring or a malfunctioning combination switch. Here is an introduction to car wipers: Function of wipers: Wipers, also known as windshield wipers, are devices used to wipe away raindrops and dust attached to the vehicle's windshield, improving the driver's visibility and increasing driving safety. Essential vehicle configuration: Due to legal requirements, almost all cars are equipped with wipers. Rear windows of hatchbacks and SUVs also have wipers. In addition to cars, other means of transportation such as trains and trams are also equipped with wipers. Some engineering machinery, such as cranes, also have wipers.

When I was driving my own car, the windshield wipers suddenly wouldn't stop, possibly because the switch was stuck in the automatic position or the relay was burnt out. Once the relay contacts fuse together, it causes the wipers to keep running, not only draining the battery but also making an annoying clunking sound. One time when I was driving in the rain, the wipers kept going non-stop, and I had to pull over quickly to turn off the power. During inspection, first try gently tapping the relay box with a screwdriver to see if it resets. If that doesn't work, you'll need to go to a repair shop to replace the part. Long-term use may lead to dirt buildup in the switch or spring failure, so it's recommended to regularly clean the wiper arm connections to prevent issues. Don't delay repairs as it could affect safety.

I've encountered the issue of windshield wipers not stopping several times, usually caused by a faulty control module. For example, when relay contacts are burnt out, the circuit remains powered, or when sensors are clogged with dust interfering with the smart system. Continuous wiper operation accelerates wiper blade wear, and the loud wiping noise at high speeds can be distracting. Before taking action, try switching to manual mode to see if they can be turned off. If that doesn't work, disconnect the battery cable to prevent overheating issues. It's best to use a multimeter to check if the circuit current is abnormally high before deciding on replacement or repair.

The wipers not stopping is likely due to a stuck wiper motor or a short circuit in the wiring harness. Damaged switch contacts can also cause the system to misinterpret and keep operating. Operationally, first check if the fuse is blown, then unscrew the wiper arm to inspect the tightness of the connection. Simple tools can be used for disassembly to easily troubleshoot the issue. This problem is common in older vehicles where aging parts become brittle and prone to failure. Regularly spraying some anti-rust agent on the pivot can help delay deterioration.
