R33 Gtst Air Con Issue

[QRI05E]

Hey guys, as all you sydney boys and girls know, today was friggin hot! on my way home from uni i turned my AC on and even when set at 18 deg, windows up (dark 15% tint) i was getting warm air coming out of the vents (approx 25 deg)... i tried using the recycle mode, i tried all fan speeds and no difference...

The AC is working for sure but isnt nearly as cold as it used to be... i got it re-gassed about 1 1/2 yrs ago and ever since then the cold temp hasnt been the same from the AC... crap gas?

Any suggestions?

Any recomended types of gas to use? anywhere in Syd that does it? Pricing?

Thanks Fellas!

Regards,

Sarkis

Mine was the same today, it was cold but just not cold enough to combat that exreme freakin heat.

I'd say it just needs a re-gas, but im not sure on price or if there is different types of gas..

I'll be looking to do the same though to mine too.

Mine is soooo cold. =-p

Maybe run through the diagnostics on the unit? If the air-temp sensor thinks it's already cold, it won't try to pump more cold in. Your gas might be fine!?

Make sure your A/C compressor turns on and off.. Listen and feel the car while you're idling. It bumps the revs around when it turns on and off. If you don't get that, then your compressor could well have died. I've heard that's pretty common.

Poor Sydney-siders, you got our stinkin hot weather that we just had in Adelaide over the last couple of days, which the WA mob kindly sent our way!

I had recently gone to a cooling system specialist and they gave me quite a good diagnosis and list of what needed to be changed and what things weren't working effectively. I can't remember most of it as I don't know alot about car air conditioners, but one thing I do remember the technician saying was that the AC lines ran quite close to the turbo and the heat from it was reducing the effectiveness of the AC system. Perhaps this is something that may be affecting your car?

I checked and made sure the AC compressor is working, and never had this problem in the past few summers up untill i got it re-gassed a while ago due to changing my AC Condensor (brand new)... so i dont think its got anything to do with the AC pipes being too close to the turbo. I'll take it down to an Auto AC place near my area and will keep you guys posted. I think just needs a decent re-gassing

there will be a leak in the system if it was working good but not anymore.

don't expect just to pay a regas charge, because you will be in the same situation in a few months when the gas leaks out again.

most ac places will do a uv and gas leak check for $44-$66 and let you know what needs replacing from there.

there is only one gas that should be used that is R134A.

Sydneysiders could check out Frosty Auto Air (Phillip Callas, 0418 608 680) he had a group buy at

http://www.skylinesaustralia.com/forums/in...showtopic=98646

and charged me the group buy price a few weeks ago, so i guess its still valid. I watched him work and was impressed. After he'd done the work he measured the pressure that the compressor was making and told me that its worn and probably wont be that cold, especially on hot days. He was right, so my cars back there now. Unfortuately he found there are no rebuild parts left for the R32 GTR compressors, so i can get a new one for $1450 (ouch) or he will see if he can find a generic replacement (he had two other R32 customers with the same issue) and wants to be able to offer an option to R32 owners after the last two new compressors are sold out (his supplier is not expecting to get any more). IIRC R33 owners should be ok.

A re-gas by itself is not a good idea, the dryer/cleaner should be replaced every two years to keep the system in good condition. Its only $220 so dont be a tight-ass, it might cost you a $1450 compressor down the track...

Thanks bud, ill get intouch with Phillip as soon as i can...

Phil fixed the aircon in my R33, it had a dead TX valve in the evaporator assembly, dryer and a full regas.

It is now so cold that I cannot direct the air vents at my face as it gives me a headache.

Great value and fantastic service.
