Greetings all. My 6 month old 2012 model Leaf cabin heater failed in May. Yes Vanessa it takes that long for new tech to filter down here to Australia. I was going to wait for the 2013 model with the reverse cycle AC to arrive but decided I might be in a retirement home by then & decided to go with the kettle.
Anyway, I checked the water temperature sensor resistance (with an ohm meter) & the heater fluid circulation pump (liquid moving in the reservoir) & both were OK so decided it must be the ceramic heater. I was confident of a fix at my 10k service. It didn't happen!
The dealership have been swapping parts seriously now this last month. They have replaced the heater, the pump & the centre console, still no joy. I'm worried this device swapping methodology could drag on forever & was hoping for a more diagnostic approach.
I've read all the service manuals I can find for the 2012 model but can't actually find a circuit diagram for the cabin heater wiring. Does anybody know where the switch that routes traction pack power to the PTC heater is physically located? Surely checking that should help narrow down where the problem lies?
Any feedback not involving lawyers gratefully accepted.
