Can someone tell me what this is??

[steve_R32]

Hey all, my A/C doesnt seem to work, I know a little about how these things work in the skylines, but was wondering what this sensor is for, and where the hell the wires *should* be going....

If somone could help me out here, it would be great

(see attached picture for what I'm on about )

Cheers,

My guess would be an A/C sensor for climate control (so it knows how hot/cold it is in the cabin.)

Yes it is the internal temp sensor for the climate control, you're correct

[steve_R32]

Cheers guys

So would I be correct in saying that with it not connected like it is at present, the A/C won't go cold? It seems as tho no matter what temp you set it on, its always on warm. The A/C compressor clicks on in the engine bay, so that sounds o.k...... I don't know. Does anyone know any more about this system??

Cheers,

Steve

From memory, it is a tube that sucks air into the sensor which is elsewhere... I dont have the R32 anymore so I cant tell you exactly

The trick is to hold the down arrow for 5 seconds after it gets to 18 degrees and FC comes up, it stands for F...ing Cold, vice versa when it gets to max temp, hold it up and FH comes up

Kewl Bozz, cheers

I tried that, and it certainly does force it to hot or cold, but after I checked the self diagnostics on the climate control, it tells me the sun load sensor, and the internal air temp sensor are no good.....(well obviously ) What sorta affect will a malfunctioning sunload sensor have on the system? See, even in FC mode, the A/C won't go cold either. (I also noticed the fan infront of the A/C condensor doesn't operate)

Oh yeah, and where are the two plain black wires from the internal temp sensor meant to be going, mine are cut, and I can't for the life of me see where they are meant to go??

Thanks heaps for the help so far guys, This site ROCKS:burnout:

The fan on the condenser (assuming you mean the one in the engine bay) is not for the AC its a thermal fan that is trigged when the engine reaches or excedes a certain temp.

ahahahahaha funniest **** i heard all morning

take it to a aircon specialist, sounds like u need ur aircon re gassed, i had the same problem last week. #22 & #25 (internal and sun sensors) came up reading as failed, they have fixed it all up now tho and it runs like a dream. take it to them and see what they say.:burnout:

[Guest gee-wizz]

I think i had a similar problem. The a/c was working fine (had it serviced) but the system was always blowing hot air no matter how cold u set the climate control. I took it to an auto sparky and it turned out a fan or rotor somewhere in the system had broken loose and had to be resoldered. been working perfectly ever since.

Cheers all for your help

Well, after doing a little more research, I found out that you have to be in direct sunlight, or use a bright torch directed straight into the sunlight sensor, otherwise it renders a fault. I did this, and sure enough only the disconnected internal temp sensor reads as a trouble fault now (and its pretty obvious why it does )

Thanks all, and if anyone can tell me where the two black wires coming outta this sensor actually go, it would be freekin excellent

Thanks again,

Steve

In the R33 that sensor is on the dashboard face behind the steering wheel
