Manual --> Auto/Digital Climate Control on 2k2-2k3
Manual --> Auto/Digital Climate Control on 2k2-2k3
Alright - I know this has been discussed before but has anyone attempted this yet on a 2k2+?
I understand that you need 3 sensors and the wiring is identical to the manual controls.
Anyone know part #'s to these sensors and what they connect to?

its gonna cost alot!! all the sensors and wiring for them. the wiring IS NOT the same. the manual one doesnt have the wiring that goes to the sensors and digital display.
and its gonna be alot of work to wire it all

the functionality is great w/o a doubt but honestly I would like to have it just to say I did it

actually all it does is look good and upscale, functionality wise it blows, the auto feature doesnt work that well in the winter. I use it mostly in manual mode. i think it just looks right, but doesnt work too well, but then again all climate controls are like that
I never ever use the auto feature. In fact in any car i never use auto
But interms of the manual to auto swap. I am just wondering, i have taking out my electronic climate control numerous times as i keep changing my system.
Is the manual control use mechanical cables to move the temperature and vent controls as opposed to motors in the electronic version?
This is a costly upgrade if the mecahnical climate control uses cables (ie, my old 96 protege used steel cables to move some leaver)..

ehh..hmm not sure what ur getting at but behind our hvac controls is two modular plugs that just plug and play into wiring harnesses--I'd assume the same two connections are present behind the auto climate
why not just call up daveb and have him fax you some wiring diagrams?
i've already pitched this to him before and he informed me that it's waaay complicated. if i recall correctly, he told me that it's not simply a matter of buying some extra sensors and pluggin them in. apparently all that wiring goes back to the ecu which is what does everything. the digital controller portion just displays what info the ecu sends it. thus, necessitating a new ecu.
granted, that was after a somewhat peripheral look at the diagrams, but it didn't sound cost effective to me.

actually i have a diagram worked out for a swap man -> auto for my brother's 96 max. I would say a dozen of wires to rewire, a few sensors... But on the other hand i still have a complete 96 i30t wiring left after a project i did like 3 years ago. Looks like a good doityourself weekend project
Auto Climate Control
Never had Climate control before my Max and now that I have it, I wouldn't buy a car without it. It's like air/cruise/tilt/keyless entry, once you have them you wouldn't go back. And MacAlert is right, when outside temp gets down to to 8C (46F) or lower then switch to ECON, it's still automatic, just cuts out the A/C compressor. This really is a wonderful system, I appreciated it in the summer and even like it more in the winter as it won't crank up the fan speed until the coolant is warm enough to provide some heat to the passenger compartment. And here is something I can't confirm but going by the sound of the fan, there are about 10 fan speeds available to the computer, and only 4 speeds available in manual mode. Setting the temp seems to be pretty accurate to me from day to day, season to season, I do notice that when the sun is shining the heat backs off considerably in the winter, and the fan drops to low before the coolant flow is reduced to the heater core, which is the most efficient process. The only negative about the system is the fact that you have to change from AUTO to ECON when the temp drops to around 8C so that your A/C compressor isn't running needlessly. Having said all that, and knowing a bit about how it works, I would suspect it would be quite difficult to change it from a manual system to an auto one, guess you'll just have to buy a new MAX! with the auto system!

my same reaction igor.
on the other hand, and this is if you're really committed to this. try to find someone who really knows ecus. they may be able to confirm if it's really a new ecu you need or a simple reflashing. i personally have no idea how they function. but it would make sense to have one ecu for all maximas and then simply flash program them on the assembly line. just a thought. that would drop the cost significantly.

for me, it was the leather issue...I hate leather and didn't want it but the only way you can get digi climate is thru leather package
hmm....oh well....

I know that for the most part this is an actuarial reason, since they have to assume that people who just don't want to pay for leather also won't want to pay for the auto control, or it's just simply easier and more profitable for them to offer them in certain package combinations. It sure would be nice, though, if one could actually order a custom car from the factory. SURELY it's possible, maybe even cost effective now that there are so many time-saving assembly line devices.
Just my two cents.

Does the ECU even have a say in the climate control? I was under the assumption the climate control was based on a small computer inside the climate control display unit... although I'd imagine it needs some kind of signal from the ECU, mainly for Engine Coolant Temperature and A/C cutoff (needs ECT so it knows when to turn on/up the fan while heating... initially in ECON mode when it's cold outside and the engine is cold, the fan is completely off, inching up 1 step at a time as the engine warms up)
All I previously wanted auto climate control for in the past was to get the outside Temp display(functionallity wise it sucked), since they started the trip computer in 02 their is no need for that for me anymore. Back in the 2nd gen and 3rd gen you could get it with cloth seats.
So does the trip computer in all 02+ have outside temp? I will be purchasing an '03 SE soon and just curious if it will have this feature? Also, does the trip computer give you gas mileage, dist. to empty, etc? Sorry, don't mean to hijack the thread!

yes to all of the above and if you get the titanium edition u also get a compass in ur rear view mirror

to the best of my knowledge, its all in the mirror
i warn u tho jason, the mirror is like $200
u need a ecu wit climate control, inside and outside sensors, climate control unit, and you have to wire the hell out of it , imo to much time and money but if someone wants to be the 1st one then good luck to em
with the manual controls, you determine fan speed, compressor, recirc. depending on the conditions, you pick whatever you want.
with the automatic unit, something has to determine what's appropriate. all you see on the display is the temp setting, but there's more to it than that. it needs to know the coolant temp, inside and outside temps, whether you're even in gear or just parked, engine temp, engine rpms, yada yada yada. it has to control the radiator fan, hvac fan, coolant pump, condensor......
not so easy igor. ideally, this is all prewired, as they do for power seats. i don't know if it is or isn't, but i highly doubt it. and there's no reason why nissan would build the automatic console with all those electronics in it when all the control wires and sensor wires already lead into the ecu. redundancy = expensive. it makes much more sense to simply have multiple software profiles which they can flash into the ecu depending on options packages.
