Rain Sensor Windscreen Replacement & Calibration
Many modern vehicles use a rain sensor mounted behind the windscreen to automatically operate the wipers when it detects rainfall. If your windscreen needs replacing, the sensor has to be removed and correctly refitted — and in many cases recalibrated — so it keeps working properly afterwards.

What is a rain sensor and how does it work?
A rain sensor sits behind the windscreen, usually near the rear-view mirror, and uses infrared light to detect moisture on the glass. When it senses rain, it automatically triggers the wipers and adjusts their speed to match the amount of rainfall — no need to operate them manually.
Do I need recalibration after a windscreen replacement?
Yes. When a windscreen fitted with a rain sensor is replaced, the sensor bracket (and camera housing, if fitted) is removed from the old glass and refitted to the new one. Budget Windscreens checks and recalibrates the sensor as standard so it operates correctly, and where the vehicle also has ADAS cameras, these are calibrated at the same time.

FAQs
What is a rain sensor on a car windscreen?
A rain sensor is a small sensor fitted behind the windscreen, usually near the rear-view mirror, that detects rainfall and automatically operates the windscreen wipers, adjusting their speed to match the amount of rain.
Does a rain sensor need to be recalibrated after a windscreen replacement?
Yes. When the windscreen is replaced, the sensor is removed from the old glass and refitted to the new one. Budget Windscreens checks and recalibrates the sensor as part of the replacement so the automatic wipers continue to work correctly.
How do I know if my car has a rain sensor?
If your wipers turn on automatically without you touching a control, or your wiper stalk has an “auto” setting, your vehicle has a rain sensor fitted.
Does replacing a rain-sensor windscreen cost extra?
Refitting the existing rain sensor is included in the standard mobile windscreen replacement service. Call 0800 282 785 for a quote for your specific vehicle.
