What's wrong with the wipers not moving?
Recently, discussions about car failures have continued to rise across the Internet, with "wipers not moving" becoming one of the hot topics of concern among car owners. Especially in the rainy season or severe weather conditions, the normal operation of the wiper is directly related to driving safety. This article will analyze the causes, solutions and recent hot topics of wiper failure to help car owners quickly troubleshoot problems.
1. Common causes of wiper failure
Wiper failure may be caused by a variety of factors. The following are common causes and corresponding solutions:
| Cause of failure | Specific performance | Solution |
|---|---|---|
| blown fuse | The wipers are completely unresponsive, but other electrical equipment is normal. | Check and replace corresponding fuses |
| Motor damaged | The wipers have no movement and the motor has no running sound. | Replace wiper motor or repair circuit |
| Linkage mechanism failure | The motor is running but the wiper does not move, which may be accompanied by abnormal noise. | Check whether the connecting rod is detached or rusted |
| Poor switch contact | Wipers intermittent failure or abnormal speed | Clean or replace wiper switch |
| Line short/open circuit | The wipers suddenly stop, possibly accompanied by a burning smell | Maintenance line connection point |
2. Recently popular topics about car breakdowns on the Internet
According to data monitoring in the past 10 days, the following are hot topics related to car failures:
| topic | heat index | Main discussion points |
|---|---|---|
| Waterproof performance of new energy vehicles in rainy season | 8.5/10 | Battery pack sealing and charging port waterproof design |
| Autonomous driving system’s ability to recognize rainy weather | 7.2/10 | Sensor interference case |
| The circuit aging problem of old vehicles | 6.8/10 | Spontaneous combustion risks and preventive measures |
| Wiper replacement cycle controversy | 6.5/10 | Comparison of service life of strips made of different materials |
3. DIY maintenance step guide
If you encounter a wiper failure, you can follow the following steps for preliminary troubleshooting:
1.basic check: Confirm that the ignition switch is in the ON position, and try to operate other electrical equipment to eliminate vehicle power supply problems.
2.Fuse detection: Consult the vehicle manual to find the location of the wiper fuse, and check whether it is blown with a test pen or visually.
3.Motor test: Disconnect the wiper arm and directly supply power to the motor (12V power supply) to determine whether it is running.
4.Mechanical inspection: Manually move the wiper arm to feel the resistance, and check whether the connecting rod connection is stuck.
5.Switch detection: Use a multimeter to measure the on-off status of different gears of the switch.
4. Professional maintenance suggestions
For complex faults or circuit problems, it is recommended:
- Give priority to 4S stores for diagnosis to avoid misjudgment leading to secondary damage.
- When replacing the motor, be careful to choose original or certified parts. Inferior motors may burn the control module.
- Special maintenance of the wiper system should be carried out before the rainy season, including lubricating the transmission mechanism and cleaning the contacts.
- When modifying a vehicle, special attention must be paid to the line load. Installing additional equipment may cause the fuse to blow frequently.
5. Sharing of real cases from users
Popular discussion cases from car enthusiast forums:
| car model | Fault phenomenon | final solution |
|---|---|---|
| 2018 XX sedan | Wiper low speed gear failed, high speed gear worked fine | Replace the combination switch assembly |
| 2015 XX SUV | Wiper automatic reset failed | Motor position sensor calibration |
| 2020 XX electric vehicle | Wipers don't move when spraying water | Update body control module program |
From the above structured analysis, it can be seen that although the wiper failure is a small problem, it involves many aspects such as machinery, circuits, and control systems. It is recommended that car owners master the basic identification methods and pay attention to regular maintenance to ensure safe driving in rainy days. Recent relevant hot topics also reflect that as the degree of electronics in automobiles increases, simple mechanical failures may hide more complex system problems, which require comprehensive judgment.
