Tundra seat heater failure

Hey, I'm having an issue with my 2008 Toyota Tundra with a gasoline engine. The seat heater isn't working. It doesn't get warm at all. I pulled the codes and found an error stored related to it. I suspect it might be the seat heating mat itself, but I'm not sure how to diagnose it further. Anyone else experience this?

I had a similar problem with my Tundra. Sounds like the heating mat is the culprit. It's like a lightbulb filament, it can burn out over time. Have you checked the fuse box?

Thanks for the quick reply! I did check the fuses, and they all seem to be fine. Was it definitely the heating mat in your case? Did you end up replacing it yourself, or did you take it to a shop?

Yeah, for me it was the heating mat. I'm no electrician, so I took it to a shop. They confirmed the mat was dead. They replaced it, and now it's toasty again. Saved me the headache of ripping apart the seat myself.

Appreciate the insight. Sounds like a trip to the shop is in order. They quoted me around 390€, so I'll get it sorted. Thanks again!
