How rain sensors are handled
Your rain sensor sits behind the glass near the mirror. During a proper replacement, the sensor is carefully transferred to the new windshield and re-seated with the correct gel pad or bracket so it reads water on the glass accurately. Done right, your automatic wipers work exactly as before.
Why the right glass matters
Rain sensors, humidity sensors, and cameras rely on the glass having the correct sensor mounting area and clarity. Using glass that matches your vehicle's features — and, on camera-equipped cars, doing an ADAS recalibration — is what keeps everything functioning.
What to check afterward
After the install, test your auto wipers in a spray or light rain and confirm the sensor responds. If anything seems off, tell us — our work is backed by a lifetime workmanship warranty. Learn more about OEM glass options for sensor-equipped vehicles.
Frequently Asked Questions
Will my automatic wipers still work after a new windshield?
Yes — with a proper install, the rain sensor is transferred and re-seated on the new glass so auto wipers work as they did before.
Do sensor-equipped windshields cost more?
Often a little, because the glass must match your vehicle's sensor and camera features. We'll confirm the exact glass and price up front.
