Defender Seat Heaters Dead, Quick Help Guide Needed

Hey there! I had a similar issue with my 2010 Discovery 4 TD last winter. The heating elements in both front seats stopped working even though the switches were lighting up normally. Like you, I was getting no heat at all. Took it to my mechanic and it turned out the heating mats under the seat covers had failed. They often wear out due to constant folding and pressure from sitting. In my case, both mats needed replacing as they had burned out sections. It was a serious repair since they had to remove the entire seat covers and padding to access and replace the heating elements. Took them about a day to complete both seats. My advice: Get it checked soon because faulty heating elements can potentially cause electrical issues if left unchecked. Also, while they're in there, have them check all the wiring connections as these can sometimes come loose over time. Worth noting, I was at 98k km when mine failed, so the timing tracks with your mileage. Hope this helps!

Thanks for sharing your experience! That's really helpful info about the heating mats. I've been worried about potential electrical issues too. Just curious, do you remember roughly how much you ended up paying for the repair? Also, has everything been working properly since you got it fixed? Mine's getting worse in this cold weather so I should probably get it sorted soon.

Hey again! Just wanted to follow up, yes, everything's been working perfectly since I got it fixed! Both seat heaters are now pumping out heat like new. I actually just had this repaired last month and it cost me 390.00 € to replace the faulty heating mat. I totally get your concern about the cold weather, that's exactly what pushed me to get mine fixed too. It was definitely worth every penny though. The mechanic did a thorough job and explained that they had to completely disassemble the seat to replace the defective heating element. Really glad I didn't wait any longer because apparently, these issues can get worse and potentially cause other electrical problems. Now I can finally enjoy my toasty warm seats again during these chilly mornings! I'd say go for it, don't wait like I did until it gets super cold. The repair was straightforward and has completely solved the problem. Let me know if you need any other info!

Thanks so much for all the details! I actually just got back from the mechanic today. You were spot on about the heating mats, mine had totally burned out too. The repair cost was a bit higher than yours at 450 € since they found some damaged wiring that needed fixing too, but honestly, it was worth every penny. The whole process took about 6 hours. The mechanic was really thorough and showed me the old heating elements, they were completely fried! I'm just glad I got it sorted before any serious electrical issues developed. Took the car for a drive this evening and the seats heated up perfectly, such a relief after dealing with cold leather seats for weeks! Really appreciate everyone's help on this. It's so much better going to the mechanic knowing what to expect. Time to enjoy my warm seats again!
