Windshield Humidity Sensor

About this product

The Windshield Humidity Sensor (#89941-76010) is a crucial component in Toyota's Electrical Heating & Air Conditioning and Electrical Windshield Wiper systems. This sensor monitors the level of humidity present on the windshield and enables the system to respond accordingly, either by activating the defrost function or adjusting the wiper speed. Over time, this sensor can become clogged or broken, impairing its ability to perform accurately. This can cause the windshield to fog up or the wipers to function improperly, negatively impacting visibility and road safety. Choosing genuine parts from Toyota ensures compatibility with your vehicle and is backed by Toyota's genuine parts warranty. Replacing this sensor at proper intervals supports the overall efficiency and safety of your vehicle, keeping the windshield clear for optimal visibility.
