Thanks for the help
Read the 9 page thread on 2013 heater failures.
Start here:

If it was me I would use an ohmeter and check the temperature sensor first and then the PTC.

Lots of 2013 heater failures and takes a long time to get the parts and the maintenance manual troubleshooting is poor.
Can lead to six weeks to get it fixed if you have a dealer that works on it.

You have a very bad situation with long drive to another country.
How difficult is it to get back home without the car?

Hy,
Thanks for the help. I agree with Nissan service in Austria that them drive Leaf next week. I can not repair itself nothing, because then will be problem with warranty. I really have a problem to get to Austria and then comes back home without heating. I hope that the defect of the heat pump resolved in one day.
All the best.

Helo,
Unbelievable, today the heat pump working again, but there is still the same fault on Leaf spy pro.
B2773 0009 HVAC PTC heater circuit 1 HAC-75
B2774 0009 HVAC PTC heater circuit 2 HAC-75
Pump operating max 1 kW even if set to max temperature. This probably will not work so for a long time? Has anyone already had such an experience?
thank you

I think there is a problem with the resistance heater, but the heat pump system is OK. You get heat with moderate energy consumption as long as the outside temperature is not too cold so heat pump works. When temperature drops low enough that heat pump will not give heat, then you are getting no heat at all because the resistance heater is not functioning. If there were problems with the heat pump, you would have other error codes. There were problems with bad heating elements reported in other threads so I suspect that you have a bad heating element (since you have already looked for loose connections and bad wires).

Helo,
Thanks for the quick reply and suport. I'll tell you proposal to service. On Friday I drive Leaf on Nissan service to review this heat pump. Can you tell me where is the resistance heater to quickly resolve the problem. It is possible to get any cutout of the service manual or picture? Because there is not many leaf at as will be for service probably the first such case and make them easier to to fix mistake.
thank you

Hy,
Diagnosis: PTC heater needs to be replaced, waiting time for PTC; one week. We'll see.
Sincerely

heat pump is locked out at -12c

I have same issue, been nearly a year waiting to get my ptc heater fixed (The only dealership technition retired!)
2013 SV Leaf, Level 2 charger, so far all works great! 130Km daily, 100% charge at night on 240 then trickle charge for 8H durring the day on 120v.

Level 2 charge starts at 130am environmental starts at 6am to 25c for a toasty warm defrosted car!
