What are the causes of intermittent failure of car wipers?
3 Answers
Car wipers intermittent failure causes are: 1. Wiper fuse blown; 2. Wiper motor burned out; 3. Wiper switch failure; 4. Wiper blade damaged; 5. Wiper linkage failure; 6. Wiper circuit failure. Solutions for intermittent failure of car wipers: 1. Replace the wiper fuse; 2. Replace the wiper motor; 3. Replace the wiper switch; 4. Replace the wiper blade; 5. Replace the wiper linkage; 6. Check the wiper circuit. The functions of wipers are: 1. To remove raindrops and dust attached to the vehicle's windshield, improving driver visibility; 2. To use wipers to determine the position of the wheels.
As a veteran driver with over 30 years of experience, I find intermittent wiper failures quite annoying. The main cause is aging wiper switches - the buttons controlling intermittent mode wear out easily, leading to poor contact or complete failure. Wiring issues are also common, such as loose/corroded plugs or rusted connections at the wiper motor. Relay failure is another major problem since it controls the wiper's delayed switching - when broken, wipers may stop or move erratically. Blown fuses can also cause this phenomenon by interrupting the current. Jammed wiper arms or overheated motors may also trigger irregular movements. When I was younger, I encountered a broken switch and replacing it with new components solved the issue. From a safety perspective, this can't be ignored - blurred vision during rain is extremely dangerous. I recommend regular wiper system maintenance or prompt professional inspections - don't wait until an accident occurs. Though small, wipers are life-critical components that demand serious attention.
As a car enthusiast who loves DIY, intermittent wiper failure may stem from issues with the intermittent switch or relay. Switch wear can cause mode switching to fail. The relay controls the circuit's intermittent power supply, and poor contact can lead to a shutdown. Corrosion in the wiring, especially at the motor connections, is a common culprit, with rainwater seeping in and corroding the joints. A blown fuse directly cuts off the power. Motor faults like stuck bearings or overheating can also cause problems. It's recommended to use a multimeter to test the switch voltage or directly replace the relay for repairs. Regularly check the wiper arm's condition when parked and clear debris to prevent jamming. DIY can save money, but if the repair isn't successful, visit a repair shop. Safe driving is always the priority. I once fixed a loose wiring harness, and it worked normally afterward.
