Getz Rain Light Sensor Issue

I'm stumped. My 2006 Hyundai Getz, gasoline engine, has a rain-light sensor acting up. Error in memory, auto-wiping is dead, and no automatic headlight control. Speedometer dimming isn't working, and the lights switch on randomly. Wiring and fuses seem fine. Any ideas?

Summary of the thread

A 2006 Hyundai Getz experienced issues with its rain-light sensor, leading to non-functional auto-wiping, automatic headlight control, and erratic light behavior. The problem was traced to bubbles forming under the gel pad of the sensor, interfering with its function. A workshop confirmed the diagnosis, replaced, and recalibrated the sensor, resolving the issues effectively.

I had a similar problem with a 2014 Volvo V60. Your symptoms align with a degraded rain-light sensor. In the Volvo, bubbles formed beneath the gel pad interfacing the sensor with the windshield. These interfere with light and moisture detection. Does your Getz have a similar gel pad? Have you checked for sensor damage?

Bubbles under the gel pad? Interesting! Where should I look on the sensor? Is it easy to spot, or do I need to remove the sensor from the windshield to see it clearly?

In the Volvo, sensor removal was needed to inspect the gel pad properly. The bubbles were small initially, so close inspection is critical. Given the age of your Getz, the gel pad may have deteriorated. While a DIY fix might be tempting, I recommend a qualified technician. Incorrect removal could damage the windshield or sensor. A workshop diagnostic scan would confirm the sensor fault.

Thanks a million for the insight! I took your advice and booked it into the workshop. You were spot on – bubbles under the gel pad! They replaced and recalibrated the sensor, and everything's working perfectly now. Cost me 62€, but it was worth it to have it sorted properly.
