Yaris Rain Sensor Fault

I'm having trouble with the rain-light sensor on my 2006 Toyota Yaris diesel. It's throwing an error, the automatic wiping mode isn't working, automatic headlight control is gone, speedometer dimming is out, and the lights are always on. Anyone seen this before?

Hey, I had a similar issue with my Yaris. The rain sensor went haywire and messed with the lights and wipers. Have you looked for bubbles under the gel pad where the sensor sits on the windshield? That was my problem.

Bubbles under the gel pad? I didn't think of that. How did you confirm that was the cause, and what did you do next?

Yeah, it's apparently common. I gently peeled back the sensor and saw the bubbles. Cleaning didn't help. I took it to a workshop. They replaced the gel pad and recalibrated the sensor. It's working perfectly now.

Thanks for the advice. I checked the sensor and found those bubbles. I'm taking it to a local workshop to get the gel pad replaced. The repair cost 62€.
