It's there right now! Turn off the CC, make sure flow-through is on and press Mode until you get dash air. I use it often.

Just build a small dial resister and switch with a 555 timer into the power circuit.
Is it that easy or am I missing a whole bunch of important stuff?

Yes, that would work if that is what you want. You can connect the output of the NE555 directly to the gate of the MOSFET.

I'm not sure if it will actually save you a lot of energy because the PTC heaters in the Leaf heat up water to around 160F. So as we all know, it takes a while until you will get usable heat in the interior. During the off periods the water cools down again, so on the next on-cycle you need to put in more energy than if it would have been running continuously.

BTW have you seen the picture I took of the hot water pipes in the engine compartment? The insulation is a joke with parts of it completely exposed. It really dates back to the ICE age where heat can be wasted.

When I find the time I will add some more insulation. That should improve the efficiency of the heating system. It should also improve the effectiveness of your idea.

Very interesting. Can you post pix of these pipes? Sound like an ready step most of us can take easily

This is awesome!! Thanks so much for posting this, I have been planning for some time to put a switch on the cabin temperature sensor for some time, but I havn't gotten around to it. I am so glad there is another circuit bender who is willing to share information here! I'd bet you are the type to upgrade your own EVSE (or build openEVSE)

I've just tested that. It works in my Leaf. With defog on, I can still switch between fresh air and recirculation.



That is strange, whenever I am on any mode that has anything to do with defog, it will not let me chose re-circulation, i have to change the mode away from defog for the button to work. If I switch mode to defog ( or feet+windshield), it forces the re-circulation to switch to fresh air. Did you do a different mod?

FYI folks, not all CC units are the same in all countries and in all model year US cars, there are multiple units. I would caution folks not to assume this is the same as Phil's modification and that there can be functional differences between units that are not evident. Even if this works on some US cars it does not mean that it wil not impact some aspects of the system. Phil goes to great lengths to test his modifications under many conditions and variables not just "it worked for me". Messing with various aspects of the car because it seems to work on one car can result in some regretful mistakes. Adding fog light and doing horn mods is one thing but these complex modifications require testing of other related systems. The CC circuit board is also quite intricate and can easily be damaged.

Dude, you live in LA. ;)
If it's 50° F or lower, the heater starts up if you have the fan on at all, even with the temperature setting at the lowest (60°).

ha!
oh, you mean it starts up when you need heat?

Yea, garsh, i getcha. you are in a range battle (choose between heat and getting home). we forget that a hoodie isnt a winter coat all around the country.
