sorry Kris I tried the scanner on the Leaf tonight while I was looking at my other problems, and it is too old....must need a consult 4 for these things. I will check a local mechanic who does a lot of modern nissans to see if he has one.
Very kind of you Duncan. I got an email from Dean finally, he means to ring Javin "to ensure they are liaising with Nissan to obtain any diagnostic assistance they may require to resolve the concern." which I hope is PR speak for "put a rocket up 'em." Hope something develops soon, I notice a chill creeping into my marriage as the missus leaves for work each morning in the electric ice box!

Ok. This has me worried. My heater is incredible! I live in Canberra and last week after a party the LEAF read -1c on the dashboard, but I started the heater earlier with my iPhone by carwings. On the drive home I had it cranked to max and my wife and I were literally sweating!!!! We turned it down to 25c, heard a buzzing noise, then smelt a burning smell, pop sound then saw smoke. After that our heater only works at maybe 30% as good as it used to. So I booked it into Nissan. 1 day before I dropped it off, our heater gets really hot again. Nissan hafts had the leaf for 9 days, found the water pump ceased, motor brush fizzled which caused a short on the same circuit as the heater core. I'm not sure if that's possible but we get our car back tomorrow. I'll be glad to get rid of this stinking diesel VW car. Yuck!! Leaf is 10 years ahead of its time.
Saw that Facebook page. Not very realistic at present. The LEAF is sitting by the sea in a built up area so it must be a long way from the snow. I doubt if they'll make it to the snow as they'd need the heater on! Where are they going to recharge on the way???

The heater in our leaf used to be great, then one night we heard a loud buzz and pop then Grey smoke inside the cabin near the front windscreen then no heat at all. Nisan inspected and found it was from a short under the dash. They fixed and it's been going fine ever since
2012 models (listed as 2013 in Oz) can have heater issues Ruth, it seems to be related to the heater fluid temperature sensor, mine has quit altogether after 8 only 8 months. Checking the climate control kw on your energy screen will definitely tell you if the heater is drawing any power or not.
Just thought I'd renew this thread as my 2011 Leaf (UK version) is throwing an error code (as seen on LeafSpy): >B2770 0009 HVAC PTC Heater Circuit HAC-75 and the heater is no longer working. Darnit, atleast it's summer atm.
My Nissan dealer has no idea and I'm not very confident with Nissan Austs lack of knowledge. In fact, recently I had an issue with the AC (no cooling) and it took 7 days for my dealer to tell me that the HV compressor is stuffed. I purchased a 2nd hand compressor from California via fleabay (AU$240 + $105 postage), they installed it for $460 and all is now good on the cooling front. Incidentally, Nissan quoted $3600 for a new compressor!
So, any advice on how to identify if the fault is associated with the temp sensor, junction box or heater?
I'm not sure if the heater in the 2011 UK version differs from the 2012 AU spec. Anyone know?
I think your heating system is the same as the Australian models. They switched to a heat pump in the newer models. Some owners on the My Nissan Leaf forums had problems with the PTC failing and there's some discussion of it here: www.mynissanleaf.com/viewtopic.php?f=30&t=28105&start=20 - page has a link to a good write-up of the problem including photos. Assuming that's your problem. Good luck!
Thanks Feng, my Nissan service bloke suggested that the UK spec PTC heater differs from the AU spec but I can't confirm. Yeah, I noticed a lot of discussion on overseas Leaf forums, will checkout you link. Cheers
