The wiper starts as soon as the car key is powered on. It may be that the rider did not turn off the wiper switch. You can check whether the wiper control switch is on, and if it is turned on, just turn it off. It is also possible that the wiper control switch or motor has malfunctioned. Generally, individuals cannot solve this situation. It is best to go to the 4s shop or related maintenance organization for inspection and repair in time.
At the same time, you can also check the wiring of the wiper by yourself to see if the wiring is incorrectly connected. Those with strong hands-on ability and knowledge of automotive circuits can try to connect the wiring correctly.
Why does the wiper start by itself occasionally?
The car wiper has a variety of working methods, specifically int, lo, hl, auto and other four. Int stands for automatic intermittent wipers, lo stands for continuous working wipers, hl stands for continuous high-speed working wipers, and auto stands for automatic sensing wipers.
If the wiper starts automatically occasionally, it may be that the auto-sensing wiper is turned on by the rider. In this mode, the wiper will automatically work through the amount of rain sensed by the sensor. Just switch the wiper to other working methods to solve the problem.
In addition, if the auto-sensing wiper starts by itself when there is no rain, it is possible that water droplets or debris have stuck to the sensor of the wiper. Just remove the foreign matter. If you don't find the specific reason, you must turn off the wiper, because dry brushing of the wiper will cause scratches on the windshield.
