GT86 Auxiliary Heater Issue

Hey, I had something similar happen on my GT86. Is it throwing any specific codes? For me, it turned out to be a faulty glow plug. Might be worth checking out, could affect the heating system's ability to start.

Thanks! I don't have the specific code right now, but glow plug sounds plausible. Was it a difficult fix? Any other symptoms besides the heater not working? Trying to see if I can do this myself or if it's best left to the pros.

No other symptoms really, just the heater failing to start. Honestly, I'd recommend taking it to a workshop to get it properly diagnosed. They'll be able to pinpoint the exact issue and replace the glow plug if that's indeed the problem. I ended up paying around 440€ for the whole repair.

Thanks so much for the information and advice! I'll get it checked out at a workshop. Knowing about the potential glow plug issue and the approximate repair cost helps a lot.
