Why does the Tesla wiper keep wiping when it's not raining?

The Tesla wiper keeps wiping when it's not raining due to a sensor malfunction. Tesla wiper: The key issue is that there is no switch in the car to turn off the wiper, you can only adjust it to 1, 2, 3 gears or automatic. Extension: The cleaning system involved in Tesla includes a set of components that can emit laser beams, which can cover a certain area of the car glass. The detection circuit can monitor whether dust accumulates in this area and automatically adjust the parameters of the laser beam emitter based on the results to ensure sufficient exposure to clean the dust.
Recently, when I was driving my Tesla, the wipers were going crazy without any rain. The issue usually lies with the automatic wiper sensor or settings. The rain sensor is located at the top of the windshield, right below the rearview mirror area. If it gets covered with dust, bird droppings, or water stains, the system may mistakenly interpret it as rain. I remember last month after cleaning the sensor, it worked fine again—it operates based on light reflection and can be overly sensitive. Setting the sensitivity too high is also a common issue in the software; my friend adjusted it lower in the settings and it worked normally. Not addressing this promptly can waste wiper lifespan and even scratch the glass, affecting safety. I recommend first cleaning the sensor with a dry, soft cloth; if that doesn’t work, check if the wiper stalk is stuck in auto mode; finally, reboot the car’s infotainment system. EVs can be a bit more troublesome than gas cars in this regard, but proper maintenance can prevent issues.
