After seeing the heater running in the middle of summer I too am considering adding a switch switch so the heater never turns on in the summer.

I used a resistor inserted into the connector at the heater fluid temperature sensor under the hood (unplugged connector from sensor, inserted resistor simulating high fluid temperature into connector, and wrapped with self-fusing insulating tape) on my 2011. This worked very well and there were no error codes set or any other problems caused by this modification. I was planning to permanently wire a suitable resistor and switch so I could enable the heater for preheat, but an errant driver forced me to replace the 2011 before I had a chance to complete the project.

The fact that the heater would still run with the A/C on is the sole reason that I did not purchase Ingineer's modification when it became available.

Is it possible to insert a resister in the outside temperature sensor to similarly prevent the LEAF from reducing regen in winter? I would love to do this if its possible. If anyone can figure this out, please let me know. Thanks!

No, the Leaf uses the battery temperature for this, not the ambient temperature...

I'd like a method that is easy to do that disables heat during the 7 to 9 months of the year I don't need it and can then be re-enabled for the 3-5 months I might use it.

I suppose method 1 or 2 would work but method 3 is out because it allows the heat to be on when AC is on.



Method 2 is the easy way to disable heat during periods of the year that you do not need to have the car heated, but a bit of cooling. The AC works, but the heater is OFF. If it is a bit nippy, you can just adjust the temperature up so the AC will not turn on. In my LEAF in additon to a aux. heater i made a small "cable kit" installed as mehtod 2. In spring i just jerk open the consol panel and find switch i have hanging loose there and turn the switch ON so that the 330 ohm resistor is in paralell. In autum I turn it off again.

I have no visable switches for this, it is all hidden under the panel. IF you want to be able to adjust the draw of the heater you can install a potmeter.

Nice YouTube video by Leafman Leaf for Method # 2:

If I do it, I'll probably leave the switch accessible rather than require console removal to switch it.

For those who do not want to "DIY" you can buy a cable kit from http://betterev.tabetalt.no/

Please note that US residents(and all other non-Norwegian residents) must add the "world wide shipping" option.

This is a less than "non-profit" project.

BEWARE: This cable kit is NOT approved by Nissan. This is MAY void warranty,

Please be aware that I am the seller of this item.


Tech info:

Mode 1: 270 ohms in parallel makes the LEAF water heater system to assume to have a very high tempt. El.hetater turns OFF.
Mode 2: 2,2k ohms in parallel makes the LEAF water heater system to adjust to approx 30 C. higher than actual temp. Less heat loss.
Mode OFF: No input. The LEAF will heat as normal,

Length of kit: 10 cm

Length of switch-kit: 51 cm.

The switch can be installed up to 50 cm (cable length) from the center console

Be aware that shipping will be primo nov to mid nov. 2015.

1 USD is about 9 NOK. Price per kit iis about 11 USD, shipping about 7 USD

I will provide a simple "youtube" video on how to install the cable kit shortly after I have received it.

At the moment I am just "covering my cost", to make sure that this cable kit is available. I am not making any money on this, but need to get my money back.

IF this project is successful I want to launch a cable kit to solve the low voltage on "high beam".

Best regards from Norway!

Thanks so much for making such a kit available! I've not gotten around to making this as I wanted something like this. I've ordered and will let ya'll know how it works after I get it it.

Hey everyone, am I wrong to believe this thread is about running the fan only in defrost mode while the car is running? If that is the case then I can say that my 2015 S model will do that with no modifications. Simply have the climate control off, then adjust fan speed with the dial. This puts the fan on without AC or heater. Then press the mode button a few times until the defrost indicator is lit. It is lit at the same time as the vent for the feet. Forgive me if I am misunderstanding what this thread is about. Good night!
