Question 5650
What happens when the windshield wiper rain sensor is faulty?
- The wiper blades work properly, but they do not clear away all the water accumulated on the windshield.
- The system cannot correctly detect the amount of rain that has fallen.
- The wiper blades leave streaks of dirt on the windshield.
Show answer and explanation
Correct answer: The system cannot correctly detect the amount of rain that has fallen.
In automatic mode, the rain sensor detects water on the windshield, and the wipers move faster or slower depending on the rain. If the sensor is faulty, the system does not correctly measure how much rain is falling, and automatic wiping does not adjust as it should. Streaks or water left behind are signs that the wiper blades need replacing.
