Crown seat heater malfunction

Hey, I have a 2021 Toyota Crown hybrid. The seat heater isn't working. It doesn't get warm at all, and there's an error stored. From what I've read, the seat heating mat is likely defective. Has anyone else experienced this?

I had a similar problem with my Crown. Does the temperature control show any unusual readings, or is it just completely inactive? It might be a faulty thermal sensor, but a defective heating mat seems plausible too.

The temperature control seems normal, no unusual readings. Just no heat at all. Where was the thermal sensor located in your case?

Okay, that sounds like exactly what I experienced. I didn't dive into the sensor location myself. I'd recommend taking it to a workshop; they can diagnose it properly. In my case, the seat heating mat was the issue, just as the error code indicated.

Thanks for the info. Took it to the shop, and you were right – defective seat heating mat. Repair cost me 390€ Appreciate the help!
