Air Conditioning Questions (again)

[Shaun]

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.

There, sitting on the thermo?

[QWK32]

mine wasn't on the thermo, if it was i would have left it there. maybe GTRs are in a different spot because of the stock FMIC.

Yah good point, my pics a GTR. I'm just taking a wild stab as i recognized the sensor in your pic

Thanks guys, ill have a look to see if i still have one.

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.
