air con probs

[junkie13]

i just bought my r32 gtr and the aircon seem not to be cold only air is coming out(the middle airvents are not there ) is there any common probs with those climate controll that i can do a check and find what the problem might be

thanks

[junkie13]

please someone help

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.

Looks like you need to regas your a/c. Make sure you have a dye added when you regas so that if there's any leak, they can be easily detected.

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

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

[junkie13]

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

Loosen your BOV

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.

i have same prob with my a/c.. got if regasses but still not working... did the test and some numbers came up on the screen.... can anyone tell me where i can reference these numbers to the problem.. cheers

[junkie13]

what number did you get and where can you get a regasses=d anscreamer i think i will keep it as i need to buy new one if i sell it

[Hiroshima Screamer]

surely the GTR manual going around atm covers this ..... ?

for everyone with aircon probs, goto www.meggala.com and find the aircon diagnostics pages and go from there...

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.

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?

[mindflux]

Heres one for you..

When i turn my aircon on it makes a constant clicking noise like somethings tyring to spin but it keeps hitting something..

anyone know what this is?
