Re: Heater problem?

Sat Feb 03, 2018 5:39 pm

I have the same problem as the OP. My heater never gets hot, and only consumes about 0.5 - 1 kWh. The outside temp has been about 40°F.

Also, once I turned on the A/C and the kWh dropped to 0 and it blew cold, moist air (fogged up the windshield). I turned A/C off and it jumped back up to about 0.5 kWh. I toggled it a few times and it was consistently dropping to 0 with A/C enabled.

I have the climate control timer set for the morning, while plugged in, and it is never warm when I get in. I'm hoping this is just a matter of replacing a fuse. Any ideas?

It sounds like the PTC (resistance) heater has failed. The heatpump doesn't work well alone at temps below 40F or so.

I think the PTC heater simply uses more juice to warm up initially and then only draws what it needs to stay hot. That's how resistance heaters work, afaik.

No, there is nothing wrong with your heater..... I believe it is a quirk in the car's computer.

I discovered this when I forgot to unplug my charger, and the car was at 100% when I was not driving anywhere. On a nice, warm day 75+, Ileft the car on, and wanted to run my heater full blast to use up some battery..... A while later, - - - Cool air just came out.

I believe that the computer senses that if the outside temperature is warm, then there is no reason for you to be blasting heat. So I believe that the Leaf only gives heat when it is sufficiently cool in the fall and winter... Maybe there is a chance for the system to overheat if the heat is blasted in warm weather..

Don't think that your car is broken, I believe it is too smart.
