air con problems

[neo32]

hey does anyone have any idears i have a rb25det neo in my r32 haveing some difficultys with air con

i put my air con into diagnostic mode and it gives me two faults one is water temp sensor witch one is this the one for the dash or the one for the ecu and also it faults on the sunload sensor and if the water temp sensor is the ecu one will it mater that its the r34 one

The sunload sensor is the one on top of the dash in the r34. Not exactly sure how it would work when transplanted into the 32.

i know what it it is but will either of these stop the air con from powerering up the compresor

[if you did the diagnostic in a garage or low light situation it will come up with a sensor problem. I checked my on my R33 in the dark and it told me there was a problem with that sensor, did it in daylilght and there was no problems. I don't think it woujld stop your air con from working though. Do you know if the compressor is OK?

I have had ongoing Aircon problems. It WORKS, but its only full cold 18`c, but anything >= 19`c it runs at full hot. Suspected that my dash cabin sensor was the culprit, but Have since been informed by Powerplay that I'm missing the external temp sensor up the front in the bay somewhere. Just waiting to get it fixed and gassed

Glad it's not just me, having the same problems with my R32, compressor didn't want to spool up, when it did it cycled on & off without cooling the car down. Diagnostic check in driveway displayed sunload sensor code, was wondering where it is & how to get to it/fix/change it. Might also get the system checked to see if it needs regasssing. Had the car for a year, no dramas up till now. Any aircon gurus out there?

If it needs re-gassing then you have a leak.

I had a dye put through mine for ~$40 with a half charge.

Turned out to be a leak in one of the high pressure hoses.

[Jordan]

Mines leaking because the origional Compressor carked it, and had a new one put it, but apparently GTR compressors dont fit the GTS-t. They FIT, but one of the connectors is too big, hence the leak. Still waiting for Powerplay to get back to me about a replacement.

Had the same water temp sensor in the same car, Neo 32. Replaced the sensor with a part from nissan (~$70) aircon works fine now.

Water temp sensor for a rb20det is the same as a nissan maxima v6 model... Yeah paid $60 from nissan... Fitted in 20 seconds with a bit of thread tape....

I'm curious as to which water temp sensor this is?

Obviously the one with the big plug? Which I am fairly sure is for the ECU and not the temp guage?

[Col-GTSX]

Thats correct.....

Hey Jordan, I have the exact same problem. Its a real pissa when u dont want it to be that cold but its too hot to roll the windows down. Could you do me a fav and pm wat the problem was, cause i'll be wanting to get that fixed. Thanks man. I wonder if we are the only ones with this problem.

Sorry for reviving an old thread.
I have this exact issue for my R33 Type M GTST here in Japan. What was the fix. It's driving me insane!
