Hi,

Ive got an R32 gtst, and my climate control is ALWAYS blowing hot air. Ive removed all the air conditioning components during an engine conversion, so im just after a fix so that the climate control will blow ambient air. Its also worth mentioning that my ambient temp displays -30 degrees.

Im just about to go through the diagnostic test (found in the tutorial section by TO4GTR), and im almost certain that the sensor at the front of the car is to blame.

My question is: Where is the sensor at the front located? Ive done alot of work at the front of the car, and there are several plugs disconnected, so i dont know what im looking for. Pictures would be a massive help if anyone could take the time.

Im sure the sensor in the stereo surround is ok. Where are the other two sensors located?

Any help would be appreciated.

Thanks,

Shaun.

this is the front AC temp sensor. if you have a front mount it would have been moved. i remember from when i put a front mount in my 32 that sensor what in the way. i cant remember exactly which side but from memory i think it was close to the bonnet latch.

i'm not to sure about the other sensors. i know one is in the cabin next to the ash tray, and i think the other is in the a/c lines somewhere.

I just had a look, and i definately dont have one of those sensors at the front of my car.

From memory, i think the sensor may have been on the bonnet latch support, but its been a long time. I not only have a front mount, but ive put twin thermos in front of the radiator, removed all air conditioning components, and have an aftermarket bonnet and latch support, so its been lost during those mods.

Does anyone have a pic of an r32 gtst external air temp sensor in the factory spot?

Also, if anyone has a spare sensor, im happy to buy it off you. Ill have to find one from somewhere, as i cant hack the hot air blowing all the time.

Thanks again,

Shaun.

I just looked in FAST and its supposed to be mounted up under the front bumper by the looks. Kind of up under the top of the main center intake duct. The FAST pic doesnt detail it too well so theres not much point in me uploading the pic. Have a look around that area and see what you can see.

...i cant hack the hot air blowing all the time.

As a temp fix, could you look up the output type of the sensor, and chuck a resistor on the pins, to simulate 210C maybe kinda?

EDIT: Checking the curve on the sensor, 210C looks to be about 2.65k Ohms.

    • Right, here's a video of the basic operation at least.  This is what you can expect day to day when you turn the car on and it boots from standby.  The only thing from a media point of view I haven't gotten working is for it to autoplay plexamp when it turns on from standby (it works from cold boot) but that's more of a plexamp problem as it will autoplay other music players.  Also attached is my one stray cable.  It's part of the screen's wiring adapters but there's just nowhere for it to go in my car.  I've just now done a bit of research and found a matching port on a 2010-2014 head unit with BOSE.  Mine has no BOSE so that's that case pretty much closed I think.  Plugging in the Infiniti AC panel basically did nothing for me, so that's a dead end as well.  Next port of call is to mess with this CANBUS module and see what I can find from it.  I found this resource containing the DBC files for a 2010+ G37 : https://github.com/icecube45/Dash_InfinitiG37/blob/master/InfinitiG37.dbc I'll now have something to go from when I try to extract my CANBUS data so I can see if the HVAC Mode, Fan Speed, Temperature, etc. match and also the gear shifter position.  It's a pretty big assumption that it's just mismatched CAN signals but considering all the devices in the CAN network are talking to each other (AC can be fully adjusted just with no info on screen) it might be a safe one.  I will report back WhatsApp Video 2025-02-26 at 12.49.10.mp4
    • Thanks for that Paul.  Do you think if I posted a picture you'd be able to remember where it went? 
    • Sorry Duncan, I didn't get a notification for the replies.  Thanks for responding!  It's a full Android device, but does allow you to use CarPlay/AA as well.  This is the one I bought from NaviRS on AliExpress: https://www.aliexpress.com/item/1005006368602668.html?spm=a2g0o.order_list.order_list_main.111.59aa1802JDzQ0E - the 2K 8G-256G CAM variant but it seems to have gone up by £170 since I bought it!  My purchase was £307.14.   It's not the fastest thing in the world but performs perfectly adequately.  It stays on standby unless I disconnect the battery and let it power down, then it's just a fairly standard Android bootup time from cold.  The DSP Equaliser is very nice and made the standard stereo system sound pretty decent compared to the stock screen.  Perhaps I can take a video of it when I get a sec. It *allegedly* supports the reverse camera, but I'm yet to get that working.  It has options for reverse cam (a camera unit can be bought separately) or 360 cameras (also bought separately).  To be fair it doesn't seem to detect that the shifter was put into reverse but I'm working on a theory about this as well.  At the moment I'm going without which is a bit annoying considering the car is an absolute canal barge but so far I haven't caused any damage I'll grab a picture of the wire I'm missing later today when I can get outside.  My theory, by the by, is that not only is the head unit different, but the CANBUS network has different signals for the different years.  I think this because I have a spare AC panel from a newer Infiniti G37 (as opposed to my Nissan panel) which wouldn't control anything except the volume when I had it wired up with the stock system.  I'm going to throw it back in and see if the screen will respond to it.  I've just ordered an arduino CANBUS module so I can have a look at the signals going around the car and see if I can spot anything.  I'm thinking if I can work out what it's expecting vs what it's getting I might be able to translate and relay the signal back but so far just a theory anyway. I also found this on my travels, so far the only one that specifically matches my car: https://www.aliexpress.com/item/1005002822934280.html?spm=a2g0s.imconversation.0.0.33433e5fgttovi If you look at the picture of the before, it has the card reader slot, and the picture of the head unit is exactly the same as the one pictured in my original post.  I asked if they sell the cables separately but sadly they won't.  I didn't want to just buy this one because it's a super old Android version and only dual core - likely slow as hell. 
    • As above, you did refill the coolant and burp the system before running it again didn't you?
    • To be fair - you see the same thing for every clutch. There's always someone making an installation error.
