The climate control in my 34 seems to not work correctly.

When in auto mode and set to any temperature the fan automatically turns to maximum and starts blasting hot air no matter what temperature i set the display too.

In manual mode, it blows cold air when set to 18 degrees and blows hot air when set to any other temperature.

It seems like the temperature sensor isn't working so the climate control can't figure out what temperature it is inside the car?

Or is this just normal behaviour and I have to live with it? Would much prefer to be able to set a temp and get it to hold as I constantly have to switch up and down from 18 to get the right temp.

ahh... not normal... I have noticed that mine doesn't heat at all if it's set to 24 or less even if the temp inside is obviously freezing.

Also, in the Nissan literature they say it can display outside temp. but I can't work that one out.

Don't think it would do anything either but I'm still gonna give it a shot.

As for the sensor not being plugged in, a problem along those lines is what I suspected but where exactly is the sensor? Couldn't quite decipher the location.

Climate Control Diagnostics R32 and R33

 

The climate control has a diagnostic mode.  

 

Enter the diagnostic mode by pressing the OFF button for five seconds within ten seconds of turning the ignition on.

Sensor check  

Sensor check is selected by pressing HOT switch (the red triangle) while in diagnostic mode. The microcomputer detects whether each sensor input signal is within correct parameters. The results are displayed on the screen.  

 

If normal, a "20" is displayed.

 

If abnormal the failed sensor number is displayed. The sensor numbers are as follows:

 

20 - all is normal

21 - outside air sensor

22 - Inside air sensor

23 - Water temperature sensor

24 - Intake temperature sensor

25 - Sunload sensor (small sensor on the left hand side of the dashboard near the windscreen)

26 - PBR

27 - Refrigerant temperature sensor

 

This should tell you if any of your sensors are faulty

have u tried this diagnostics method on the 34?

ok i just tried it.

and I got into the diagnostic mode.

here is what I found.

when you turn the temp knob all the way to the coldest, it seems to be in "light + LCD test mode" as all the lights on the aircon unit light up and all the icons on the LCD are visible too.

next if you turn the temp up slowly, I think 2 or 3 degrees up, you will get in to what I think is the sensor test as I received a 20 meaning no problems, you might receive a different number here NJR 34GTT since your aircon is playing up.

the next few modes I have no idea what they are, they gave me a 5 and a 41 from memory.

Yeah I tried the diagnostic mode and got what I expected a 22 and a 25. The 25 being from the fact the car is in the garage. I suspect they didn't reconnect the internal sensor properly when my profecb handset was disconnected.

Now the task of pulling apart my dash just to get to that sensor and the back of the climate control seems a little daunting.

Happy to know that I've determined that it is the internal temperature sensor though.

Thanks guys.

Oh and I noticed that weird grate symbol too.

i got a 25 too!! but my climate control is running fine,,, heats and cools when its supposed to,,

i haven't tried looking for the sunload sensor,, so where exactly is it on top of the dash?

i think that grate a/b symbol if for the internal air filter,,, will light up if its gets blocked i guess,, the r34's came with an air con air filter. there is a thread on sau about how to go about removing/cleaning the air -filter,,

ok...34 gtr hot/cold control knob pushs in to display ambient temp....to takeout the sun sensor....remove the whole grille that holds it there is no bolts to hold the grille in...it just clips in....pry it out with a screwdriver

    • Also, I logged some data from the ECU for each session (mostly oil pressures and various temps, but also speed, revs etc, can't believe I forgot accelerator position). The Ecutek data loads nicely to datazap, I got good data from sessions 2, 3 and 4: https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-2?log=0&data=7 https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-3?log=0&data=6 https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-4?log=0&data=6 Each session is cut into 3 files but loaded together, you can change between them in the top left. As the test sessions are mostly about the car, not me, I basically start by checking the oil pressure (good, or at least consistent all day). These have an electrically controlled oil pump which targets 25psi(!) at low load and 50 at high. I'm running a much thicker oil than recommended by nissan (they said 0w20, I'm running 10w40) so its a little higher. The main thing is that it doesn't drop too far, eg in the long left hand fish hook, or under brakes so I know I'm not getting oil surge. Good start. Then Oil and Coolant temp, plus intercooler and intake temps, like this: Keeping in mind ambient was about 5o at session 2, I'd say the oil temp is good. The coolant temp as OK but a big worry for hot days (it was getting to 110 back in Feb when it was 35o) so I need to keep addressing that. The water to air intercooler is working totally backwards where we get 5o air in the intake, squish/warm it in the turbos (unknown temp) then run it through the intercoolers which are say 65o max in this case, then the result is 20o air into the engine......the day was too atypical to draw a conclusion on that I think, in the united states of freedom they do a lot of upsizing the intercooler and heat exchanger cores to get those temps down but they were OK this time. The other interesting (but not concerning) part for me was the turbo speed vs boost graph: I circled an example from the main straight. With the tune boost peaks at around 18psi but it deliberately drops to about 14psi at redline because the turbos are tiny - they choke at high revs and just create more heat than power if you run them hard all the way. But you can also see the turbo speed at the same time; it raises from about 180,000rpm to 210,000rpm which the boost falls....imagine the turbine speed if they held 18psi to redline. The wastegates are electrically controlled so there is a heap of logic about boost target, actual boost, delta etc etc but it all seems to work well
    • hahah when youtube subscribers are faster than my updates here. Yes some vid from the day is up, here:  Note that as with all track day videos it is boring watching after the bloopers at the start.  The off was a genuine surprise to me, I've literally done a thousand laps around the place and I've never had instability there; basically it rolled into oversteer, slipped, gripped and spat me out. On the way off I mowed down one of the instructor's cones and it sat there all day looking at me with accusing cone eyes as I drove past. 1:13:20 was my fastest lap, and it was in the second session, 3rd lap.  It (or me!) got slower throughout the day as it got hotter.      
    • It sounds like you want what the Toyota Landcruisers have for their roof racks. Wanna know what you end up with? Rust holes in the roof, and water everywhere...
    • Discovered today that if I select reverse first and take my foot off the brake, then select drive, the drive indicator light works and so does the tiptronic gear indicator. 
    • Ok so after much research and talking with knowledgeable people I've got my turbo conversion done and it's all running great other than 1 small issue.  Car has remained auto with the na auto and tcm, I've used a stagea ecu with. NIstune board and everything is great other than my gear selection on the dash. It illuminates park, reverse, neutral, 3rd and 2nd. But nothing drive or what gear your in when you pop it into tiptronic.  I'm sure there is maybe 1 wire in the ecu plug I need to move to rectify this. Does anyone here have any ideas?   Cheers guys
