Driving back from Airteriors the other day and had my 12v heater plugged in to the fag lighter. It was happily blowing for most of the journey until I stopped and turned the engine off. Got back in to drive off again it had stopped working. I unplugged it and plugged it back in and still nothing. Swapped it for my sat nav but that wouldn't charge either. I changed several fuses today to try and eliminate if one had blown but still no luck. So, my question is, do you think it is a fuse or something else? Tried the heater in my Disco and it works so I know it's either the lighter or the fuse or the wiring. Which fuse is for the lighter? What do I try next?
The fag lighter will have been put in by a previous owner, so how it's wired will depend on how they've done it. I'd fuse the socket at 8A, as the socket can't handle much more: suspect your heater has overloaded it. Trace the wiring from the socket back under the dash to check for signs of damage.
Traced it best I could but couldn't see anything obvious. I guess I need to spend a bit longer upside with my head in the footwell!
