What Causes the Wiper to Wipe Automatically?

[Quentin]

The wiper may wipe automatically due to a circuit short, sensor malfunction, or accidentally touching the switch while driving. Analysis of Automatic Wiping Causes: Accidentally touching the window washer switch may cause the wiper motor to operate for about 3 cycles as set to clean the glass; the car is equipped with an automatic rain-sensing sensor, and if the sensor malfunctions, it may mistakenly detect heavy rain and activate automatically; a short circuit in the wiper switch circuit may directly connect to the wiper motor, causing it to operate continuously and requiring inspection of the related wiper circuit. Solutions: When turning off the wiper, be cautious. If it does not stop at the initial position, stopping it immediately may block the view and affect driving safety; if the car is equipped with an automatic rain-sensing sensor and the sensor malfunctions, the rain sensor or its wiring needs to be replaced or repaired; the wiper control is managed by the body control module, and if the body control module program malfunctions and sends incorrect commands, the body control module needs to be inspected and repaired.
