A Rock Chip Repair on a Rain Sensor Windshield

Question:

Will a rock chip repair of a rain sensor windshield affect the performance of the rain sensor?

Answer:

A rock chip or other windshield repair made in the area of the rain sensor will negatively alter the performance of the sensor. The rain sensor must be able to “see” clearly through the glass in the area where the sensor is mounted. The sensor depends on the light reflected and transmitted through the glass. A break in the glass where the sensor is mounted will cause the light to scatter as it passes through the glassmaking, the sensor work improperly. Even after a break is repaired, the break is slightly visible and will cause the light to refract differently than unbroken glass.
