Thank you for your response! You mentioned checking the wiring and plug connection. Were there any specific signs of damage or corrosion that you observed?

To be honest, I didn't see anything obvious at first glance. But when I wiggled the connector a bit, the heating started working properly for a few seconds. That's when I knew it was a connection issue. I'd recommend checking that first. But if it is not the cable, I think you should go to the workshop.

I appreciate your input regarding the wiring and plug connection. Following your advice, I inspected the wiring, and indeed, the cable was defective. The repair cost 95€. Thank you again!

Hey there! I have a Sonata too and I think I know what you mean. I had a similar problem with the heating in mine a while back. Have you checked the wiring and the plug connection to the sensor? That was the culprit in my case. I would check the cable first before spending money on a new sensor.
