You can do a diagnostic on the climate control, it will tell you if the sensors are stuffed. Turn the ignition on, hold the off button for five secs or so until the screen comes on, then press the temp increase button and it will flash a code. I cant remember what is what but im sure its been posted here before.

yeah its not good idea to be driving with no gas in the air con over works the motor big time and your prob dose sound like lack of gas , off the topic question what bov did you end up getting with your car man ?

i got a 32 gts-t i dont know if its the same as GTR but i had the same problem and i thought the same..needs re gas but i went to get it done and the guy said it was fine. Found out it was to do with the pump. It wasn't starting when i turned the air con on. So i had a sparky wire me in a overide swith to power the pump and what happens is i turn the air con like normal...wait a minute and if it doesn't come out cold turn it off..flick the switch on then turn the air con back on and Bobs your grandma...it works :cheers:

just thought i let you know incase you go to re gas it and it already gased

how do i know if there is no gas in the car or not and where i did the test it came as no. 20 what does this mean and i got the hks type 1 bov but it dosnt make no noise very disspoint it at having atom. bov and no sound

they dont work sell them to me.... :wassup: if you get hot air when you put air con on it means that it needs a re gas.

Hiroshima Screamer - If there is no gas in the system you cannot damage the aircon compressor as there is a low pressure switch which will stop the compresser from cutting in.

KBNR32 & junkie13 - Have a mate turn your aircon on while you are looking at the front of the aircon compressor, if its working then you will hear a "click" and see the front clutch engage, the revs should also pick up approx 200 rpm. If the clutch doesn't engage then you have:-

i) a stuffed compressor

ii) no gas in the system and therefor the low pressure switch is not allowing the compressor to kick in.

To check if there is a problem in the ecu run a live 12V connection direct to the compressor's input and see if the clutch engages.

Hope this helps as I have been there myself.

i was made to understand by not having the air con working properly and using it could cause the motor to work overtime thuss engine temp will go up ? This would be a result of only having the engine fan cooling the motor as aposed to having both fans working as a cooling system.When there is no gas in the system the sensor automatcially cuts out the fan meaning the engine has to count on the one fan to do the whole job.Not pretending to be an expert just sharing what i was told when i was encountering similar probs.

  • 2 weeks later...

any of u guys know where the refridgerant temp sensor is.... i have found out through diagnostics that this is causing my a/c probs... it is telling the computer it is 2 cold... thus everytime u turn the a/c on... it turns itself off again..

Plz help.. so i can get this fixed asap..

Thnaks

by the way anyone know what re-gasses cost? its like $90 isnt it? im pretty sure thats why mine blows hot air, but with autumn and winter around the corner im not really worried, P.S does aircon cause ur car to eat more petrol? i thought it was cause u had to drive it a bit harder because the aircon takes away soem power, am i wrong?

    • Ha ha ha, this stuff they had was installing Toshiba PLCs that were made some time in the 1990s, and they were replacing GEM80 PLCs. To let those two talk (staged upgrade along a ~1.2km long building that was split into 4 sections), was a bunch of WinXP machines running Java gateways... There was no way to put something like ProfiSafe in... Most of the HMI machines were WinXP, with Java program, with a custom button board emulating a keyboard... About the only buttons in the operator stations that went direct to the PLCs was the eStop. There was some interesting design stuff in that place...
    • Stock bypass valves are good for plenty of boost.
    • Check for fuel flow out of the outlet end of the rail. Check for spark. Try to start with aerostart (or pressure can brake cleaner or similar solvent in a car) prayed in through TB. If you have fuel and you have spark and it will fire on substitute fuel, then seriously suspect that E85 sitting for ages in your fuel system has destroyed something and put it in your injectors.
    • Nissan stock oil pressure is typically about 1 bar at 1000 rpm plus about 1 bar per thousand revs on top.
    • Luckily for safety applications, with dedicated links not being used for any other traffic, you simply run ProfiSafe (or an equivalent safety comms protocol from other vendors) over the top of ProfiNet (if that's what you're using, or Ethernet IP if you're stuck in the world of American PLCs and not verking vis ze Chermans) and the redundancy is more about being able to know that you need to cause a system diagnostic lockout because you've lost one of your comms channels, rather than not knowing that you've lost your only comms channel. Granted, heartbeats and all that are possible and useable and all that, but some safety applications are are so time critical that you might not be able to afford a few milliseconds until the next check.
