Basically, you need to find out what cabin temp range is needed to get the Floor-Defrost combo in Auto.

Regarding cold weather driving --

I'm pretty happy with low setting seat heating and enough outside air ventilation to keep the humidity down so that the glass does not fog up. The car stays at ~ 4.5 miles/kWh.

Admittedly I've only tried this down to the mid 20s F for trips under 30 minutes, my climate is dry, and I am not cold sensitive so long as I am wearing gloves. YMMV

A problem that I'm having that this feature (or glitch) solves it's that when it's this cold (it's -27°F/-33°C right now) is that any sort of moisture, including breath, doesn't fog the window windows, it freezes to the windows. So instead of scraping the inside of the windows this gets the inside air blowing onto the windshield hot enough to melt and blow it off. If I turn on the normal defroster the inside air temperature drops instead of rises because it's trying to heat up -27°F air.

I'm actually tempted to build some sort of auxiliary heater for my Leaf because of the super cold temperatures we experience here in Gunnison. I'd prefer it to be electric powered, but even if it were fuel powered at least fuel heating can be +90% efficient.

I've noticed the "cold spot" in my Leaf is about 18-22F, this is cold enough that the heat pump can't really make any heat. Even at full it's probably only 75F maximum. Add on that driving at night with no sun and it's at the point where the heater isn't really heating the car any more.

Once you drop below 18F then the restistive heater kicks in, you'll see your CC power consumption go from 1.5kw to over 3kw. My question; has anyone found a way to "force" the resistive heater to come on at higher temperatures? I would like to be warm on journeys I'm not range limited.

And yes, if someone finds a way to override recirculate in defrost mode you win the thread.

.....
I have the habit of hitting Auto then selecting fan speed as a quick way to get out of defrost and not having to look to see if I'm selecting feet or not as I scroll through the different vent modes.

Sounds like a good tip, I'll give it a shot and report back how it works. I'll try it on my '13S I'm driving today and later on my '12SL who's dash looks just like your photo.

Well I tried to use AUTO and recirc to work on both my Leafs but on both when I pushed the recirc button while in auto it wouldn't go on, just like I didn't push the button.
Now admittedly it wasn't that cold when I tried it, 20s to low 30s and it sounds like later in this thread you mentioned it had to be colder but I think for now I'll just stick to my normal floor + windshield, fan set to either 1 or 2 and temp set to 77, or any high number and I'll just have to pay the price in running 100% fresh air. I know others have had luck with floor only keeping the windshield clear enough but whenever I've tried that it starts fogging over within several minutes :(

When you push Auto does it automatically chose defrost? If you hit Auto then manually select defrost it won't work.

No when I push auto it only goes to floor......again probably because it's not cold enough out?
When in AUTO if I push any button(manually select direction, fan speed, A/C, etc.) auto immediately goes off. Other buttons like recirc just don't do anything, like I didn't push the button.

Mmm... Strange. I'll try to post a video of what is going on. Maybe this is just a (handy) glitch that only happens in my Leaf?

Here's a little tip: check out your front undertray. I was just looking at mine and noticed that it had torn from its mounts and the front corners were hanging down under the car. The undertray is made from some kind of fiberboard and simply tore. Most likely caused by the previous owner pulling too far into parking barriers or curbs and scraping it repeatedly. Just throwing away kilowatts with this not fastened correctly.

Leaf that have HEAT button on CC panel:
AUTO engages partial recirculation if heat is needed.
No need to hold recirculation button, it just defaults back
recirculation mode into AUTO (aka third-recirculation if heating engaged).

AUTO almost always keeps airflow setting at defrost+feet in cold (sub-freezing) weather.
Only if there is a lot of sunshine and cabin is fully warmed up, it might switch to feet.

PS! Selecting FEET actually keeps defrost vents active with limited airflow.
To save energy (and it's not very damp) you can manually select FEET, glass will not fog up.
To have more air to the feet or defrost while in defrost+feet or feet mode, close left and right face-went.
To save even more manually stuff up rear passenger foot ventilation.

Selecting face+feet will totally block airflow to windscreen, same with face only.

Also full recirculation is possible with defrost only on newer CC panels with HEAT button.
Just select defrost with MODE button and push recirculation. Useless mode, it fogs up.


TIP: if you want to keep Leaf running with heater working and also want to save juice, push
recirculation button when you exit the vehicle (and there is nobody inside). It will not fog up
as there is no moisture buildup. Except if everything inside is wet :lol:
