Definitely interested in this. When you say "semi-permanent", is it correct to say that the mod can be disconnected if the HVAC system needs service by a Nissan dealer?
FYI: Messing with the LIN comms will cause DTC's to be set. That is not how I implemented this, nor did I use any relays. All solid state!palmermd said:It looks like the same solution that I came up with except it is using an existing signal. I'm installing a relay and using the normally closed contact on the LIN signal to the heater. With the car powered off the signal is closed so that remote control of the heater will work as normal. Once the car is powered on, power to open the relay is fed through a switch that I am adding. This will give me a switch that will disable/enable the heater.
The genius of Phil's mod is that he seems to be using the auto illumination signal to trigger another relay instead of using the switch. This eliminates the need for an additional switch added to the system. I still think I'm going to use the separate switch, because I'd like to have control of the heater in auto and manual modes.
Yes, the upgrade can easily be disabled with no tools required.dgpcolorado said:Definitely interested in this. When you say "semi-permanent", is it correct to say that the mod can be disconnected if the HVAC system needs service by a Nissan dealer?

All they'd have to do is send me the source code for all the ECU's in the car, and I'd fix all the issues! The LEAF could be so much nicer with all these little things fixed. It's really evident they were in a hurry.LittleChap said:Count me in! TomT definitely has the right idea:

My original idea was to tie it in to the A/C, but I am fine with the A/C being on most of the time, as it drains such little power. I know it won't be on unless the car is hotter than the temp I set, which is not the case for the heater.Electric4Me said:I paid closer attention to the climate control operation this morning on my way into work. I realized that when you press any button besides temperature up/down the auto light will kick off. The system still seems to operate in "auto" with the exception of what you overrode. Because of this, I think I want more control over the heater than just when it's in full auto. Either manually switched on/off or what I'd prefer is to be in synch with the A/C switch. That would make the system function in economy mode or power assisted mode...
That would definitely be my preferred choice, although Phil's mod would obviously be a huge improvement.Electric4Me said:... I'd prefer is to be in synch with the A/C switch. That would make the system function in economy mode or power assisted mode...
