R33 Air/con Problems

Hey guys and Girls,

Coming into summer now (well sort of, more like a lack of summer) I have found that my Air/Con on my R33 GTS-T, serious 1 has decided to be a moody cow and have a mind of its own as to when it would like to work.

Sometimes it will make super cold air, while other times (without changing the temperature on the a/c unit) it will be room temperature, or just below room temperature. Really freakin frustrating.

The compressor turns as soon as I press the a/c button, but I get no cold air inside the cabin. I got my gass checked and apparently there is plenty of pressure, the guy said there would be a leak somewhere in the system, and I quote the air/con dude “I would be looking at thousands of $$$ to get it fixed”

Has anybody had this problem? if so could they tell me how they fixed it!

I want to try and give it a go at fixing it myself, or at least telling the air/con guy where to start looking to fix the problem any help or advice would be much appreciated.

Hope to hear from you soon.

Vlad

if it has a full charge of refrigerant why is he telling you that it has a leak somewhere??

I would have a guess that your TX valve is faulty and only opening and closing some times..

I would take it to someone else that knows what they are talking about..

+1 for taking it somewhere else. with a set of gauges connected they should be able to tell you if its low on gas, tx valve fault, clutch slipping etc etc. wont cost much just to get a diagnosis. and would have to be extreme to cost thousands.

Thanx for the help guys, really appreciated :thumbsup:

What is a 'TX valve'?

&

Where is it located?

Is it something I could give a crack at fixing myself? Or is it better of to get a 'professional" to fix?

Once again thank you for your advice, i really need my air/con! (I know I'm a big ferry, i just don't handle heat all too well)

The TX valve is the part that controls the flow of refrigerant causing a pressure drop which causes the cooling effect..

You can not do anything to the A/C system yourself..

Firstly it is illegal as you don't have an automotive refrigerant handling licence

Secondly you don't have the correct tools to recover the refrigerant, vac the system out and avoid contamination..

I would just take it to another mechanic if i were u..

lets clear a couple things up. a tx or thermal expansion value coverts your low pressure liquid into a high pressure gas. if you get the gas taken Out by the ac shop you can work on it yourself. buy a new tx value - not from nissan! and put it in then get your regas. tx value is located up behind the glove box. takes bout half an hour. got any questions pm me.

My clutch slips/plays up when I turn my aircon on, the revs drop a little but my actual clutch doesn't engage or disengage properly and it's really pissing me off! I hardly ever use aircon but with summer here and the Perth heat, I might need it for them extra hot days! Anyone know what's causing this or how to fix it? I know it's not my clutch, I just installed an Exedy HD clutch about 2 weeks ago, cheers

your gearbox clutch slips with aircon on?

what do you mean it doesnt engage or disengage properly?

      I replaced the whole clutch line with the chase bays braided hose, I think it removes that loop, is it the short hose that comes immediately off the slave or is there a drawing in the manual to find what you’re referring to? It was just re-bled when I upgraded to the nismo slave, old slave worked fine but I thought that might help, didn’t change a thing. It’s like the first half of the pedal is pushing air and then when it finally actuates the master the friction zone is tiny. Makes it practically impossible to launch the car

      Yep, that was one of the things we learned fast in the past with our MX5. When you drive with the top down, you are effectively standing out in the sun, 100% of the time, and not getting in any shade (because roads aren't shaded generally!). Just like standing out in the middle of a field on a sunny 27C day is a bit of a bad plan, so is sitting in a MX5 without sun protection.

      I also just ordered some Frankenstein bolts and side mounts to fit a hard top Just in case I do find one, basically so it doesn't need to be fixed to the car with only the front latch.......and then gaffa tape to keep it in place for the RTN journey from wherever I get it

      If your temps are fine now, you probably won't have any issues with where your vents are as they don't look right up at the windscreens high pressure area, so any differences when giving it the beans for extended happy laps would be minimal, but, they should vent heaps when stuck in traffic  Much like how that reverse cowl on my SS let "visible" heat out when stationary, but, because it was basically at the windscreen my coolant temps on the Hwy actually raised because air was being fed into it at speed (110kph), to only come back down to around 90° when I got off the Hwy And your 100% correct about the NC currently not needing vents, but, if I was to add a turbo, and a oil cooler and intercooler in front of the condenserand radiator, and then take it to the track???? It is apparently a recommend requirement if I don't want to worry about coolant or oil temp issues, but, any of the above are possible scenarios, over time As it sits now, with the triple pass radiator and stock air conditioning system, I have absolutely no issues with either temps or air conditioning efficiency, I've been basically daily driving thie car for the last month, both on the Hwy, and peak hour, bumper to bumper traffic, but, that's pretty much expected from basically a standard engine  Talking about no issues daily driving, it was 39° the other day and I was sitting in bumper to bumper traffic on the M5 and then M7, with the top down, and with the air conditioning blowing nice cold air on my feet, balls, and face, well, there was one issue, my head and arms got pretty sun burnt Note to self: leave a hat and sunscreen in the car for such days 🤣

      I would agree, unless you need something specific to the HV motor/battery side repaired or investigated, any mechanic will be able to perform normal services, but if you prefer, maybe look for a mechanic who regularly services/repairs Nissans, the VQ engines are pretty common in the Nissan lineup.  Sorry, I can't make any suggestions, I don't live in Vic.
