The rain sensor has a system that activates the windshield wipers automatically by detecting rain on the vehicle's windshield.
Rain sensor operationThe rain sensor can be found behind the rearview mirror and it is easy to notice the sensor because a strip of the lens can be seen facing the outside. The sensor is usually alongside the light sensor, and the sensor can detect it is raining by calculating how many drops are on the windshield. The rain sensor is a helpful system that keeps your sight light clean and engages the windshield wiper so you won't have to worry about turning it on or off.
