Non-Navi AC Controls

mlsully

If it wasn't a hard request, then why are you asking and not figuring it out on your own?

Its not easy to answer as the average person wouldn't really know how may clicks within that dial actually change the speed of the fan. You would need something to measure either the fan speed at each click to determine if each click was indeed an increase, or just a gap between the next actual speed adjuster. Or, you would need to meter voltage/ohms from the AC amp output to see thew step changes.

I use AUTO and MAX settings & nothing else for fan speed. AUTO does the job 99% of the time and the 1% MAX is for demist screen when needed.

Regarding where the air comes out I use AUTO and SCREEN DEMIST only.

I have never used auto AC. I need to get with the times.

I don't have that model Z and figured there were tons of people on the forum that did.

My Navi model has 7 discrete fan speeds, and it is very noticeable when going from one to another. I was just curious if a similar determination could be made on the non-nave setup. If not, it would indicate that there are many more fan speed selections that can be made with the dial control, which would be interesting.

All of the controls are pretty self described, but the intermediate selections between the modes I pointed out in the pic are not labeled or defined in the matrix in the FSM.

I was hoping someone with that model Z could simply go out to their car and see what their AC does in those modes.

Hope this answers fully for you. It took me all of 10 min to answer so no problem.

A/C Control - 26 positions
1 - off
2 - auto
3 - 25 fan speeds

Temp Control - 30 positions
1 - 60
16 - 75
30 - 90

Airflow - 8 postions
1 - Auto
2 - Face
3 - Face / Feet
4 - Feet
5 - (mix)
6 - Defrost / Feet
7 - (mix)
8 - Defrost

BTW, I have 2016 Nismo Tech and bought this system from Non-Nav with intentions replace my Nav system to be able to install Cubby tablet. I gave up though due to need to hack up multiple harnesses. If you or anyone needs the Bose radio & AC controls from 2014, I'll make you a good deal!

Thank you ltullos! So, what happens in mode 5 and 7 exactly? It is confusing because mode 6 would be a "mix" of 4 and 8, so I was wondering what is different in mode 5 and 7. Is mode 5 more feet and less defrost than mode 6? And mode 7 more defrost and less feet than mode 6? Strange that the mix modes are not documented in the FSM.

This is exactly why I am working on a better solution. I (and assume many others) would like to move away from the stock navi in a non-invasive way. The goal of this is to provide a plug-n-play solution to non-navi AC control in a navi based model without swapping the AC Amp and doing a bunch of wire work.

I appreciate the help!

since i don't have this system in the car, I can't check modes 5 & 7, but i'm guessing that airflow is directed 25%/75% rather than 50%/50%. Hopefully someone else can help you confirm or correct.

Oh, right. Haha... duh
