Rain & Humidity Sensor

About this product

The Rain & Humidity Sensor (#89941-11010), an Electrical part of Toyota's Windshield Wiper system, plays a crucial role in maintaining visibility during inclement weather. It automatically detects rain and changes in humidity, prompting the wipers to adjust their speed accordingly. The sensor’s functionality hinges on a system of infrared light. If rain or high humidity is present, the light's reflection alters, triggering the sensor. However, like any part, it may degrade over time, become clogged or break. A malfunctioning sensor can lead to poor visibility in changing weather conditions, risking driver safety. To uphold compatibility and optimal performance, always opt for genuine Toyota parts. These parts, including the Rain & Humidity Sensor (#89941-11010), come with Toyota's genuine parts warranty. Remember, regular replacement of this sensor substantially contributes to the safety and efficiency of your vehicle's windshield wiper system.
