Re: Easy Climate Control Fan-Only Solution - 5 cents, 5 mins

Can somebody explain the difference between Phil's mod and this deluxe version? Is Phil's mod more firmware related while this deluxe version is a hands-on components replacement/add-on?

Phil said his mod can be reversed easily using a simple switch (not clear what switch he was talking about, though). I assume that this deluxe version cannot be reversed easily?

Never had that during pre-heating. Have you tried one of those dehumidifier dry packs? I've read that they work quite well.

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

I've never seen Phil's solution but I've read what he wrote in this forum. He said his version does not modify the firmware. With being reversible he explained that there is a wire loop coming out of his modified unit that can be cut to disable the mod.

You can do the same thing with my version if you like. Just put a wire and/or switch between the 330 Ohm R1 and pin 37.

This is just speculation but I assume Phil might be using the same underlying principle to trick the climate control unit.

Thank you!!! I can't tell you how happy I am that someone has actually built this the very same day that I posted it. That really made all the time it took to document what I did worth while.

I'm glad to have shared this with you all.

It's awesome that you did take the time to do it. This will help a lot of 2011 and 2012 owners without the heat pump heater option to get more range without fighting poorly designed HVAC controls.

Congrats on a job well done.

AFAIK, Phil's solution is the same as the "deluxe" version, except that his also enables the heater if the rear defogger is activated (uses it as an "override"). I suspect his implementation is similar, or maybe a little cleaner with an add-in circuit board instead of flying components.

BTW, I bought Phil's and am quite happy to support his efforts.

I can't understand this. Why in the world is there no 'ram-air' system were one can jut get flow-through air from the dash vents without running the fan at all, and why is there no eco setting on the HVAC that kills the A/C compressor or the resistance heat system?

Most regular gasoline cars have these basic features (well aside from a resistance heater kill switch....).

It seems as though it would save energy vs running the AC/heater or driving with the windows cracked open/down.

Thank you for posting it! A cheap and simple but elegant solution.

I enjoy reading all of the creative ideas that make our Leaf an even better car. In fact it's one of the most fun parts of owning our car.

But I have a question and an idea that perhaps some one who knows more about our car can comment on.

I have felt that the climate heat and defrost system would work just fine for me if i could "pulse" the controls.

Give me a 1 minute blast of defrost with heat and 3 minutes of "off" (for example) make that circuit variable so that I can dial in the delay and I get a clear window and save 2/3 of the power.

Let me have that same system for the heater, run for a few minutes, off for a few minutes.

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?
