Just done a bit more reading and found out it may be the magnetic clutch or the fuse, but the fuse layout on the box is all written in Jap so if anyone has a layout of the fuses for an R32 so I can workout which fuse is the one for the a/c that would be great. I have been searching on here for a fuse layout but having no luck

Can you read this;

I got the sticker from ebay - worth having.

IIRC its the top row fourth from that right that blows when the mag clutch dies. IIRC the winding is supposed to be 3.5 ohms - mine was half that and blowing fuses before i replaced it. If you dont hear the clutch throw with a click when you turn the AC on, its a good place to start looking.

Hey guys,

I too am going through R32 air con problems. My servo motor is moving, I had my air con re gassed and serviced but no luck. I found a way to run the air con in diagnostic mod and the A/C does get cold in that mode... Just not in normal mode.

According to the following my outside sensor is causing the problems.

So if you need to test you sensors here is the instructions for Diagnostic mode.

Climate Control Diagnostics R32

The climate control has a diagnostic mode.

Enter the diagnostic mode by pressing the OFF button for five seconds within ten seconds of turning the ignition on.

Sensor check

Sensor check is selected by pressing HOT switch (the red triangle) while in diagnostic mode. The microcomputer detects whether each sensor input signal is within correct parameters. The results are displayed on the screen.

If normal, a "20" is displayed.

If abnormal the failed sensor number is displayed. The sensor numbers are as follows:

20 - all is normal

21 - outside air sensor

22 - Inside air sensor

23 - Water temperature sensor

24 - Intake temperature sensor

25 - Sunload sensor (small sensor on the left hand side of the dashboard near the windscreen)

26 - PBR

27 - Refrigerant temperature sensor

This should tell you if any of your sensors are faulty

hope this helps.

Since buying my car about 4 months ago the a/c has never worked. with the recent heat wave I thought i'de better do something about it. Put it into dianostic mode and came up with 25 and 27. 25 as expected. the sensor relating to 27 kept fluctuating from -30 to 0 and +30. I disconnected and bridged the connections which gave me a constant 46 degrees. You hear the a/c switch to full mode but the compressor does'nt kick in. After further investigation I discovered that the 2 electrical connections on the compressor were disconnected to I reconnected them thinking this was the problem but it made no difference. I've checked all fuses which appear ok, so I disconnected the plugs again to check the voltages. The plug with the 2 wires read 0.2 volts each to earth. The single cable plug read 0.045 volts obviously no where near enough to make a compressor work. Does this pressure switch cut power to the compressor? If so can you bypass it so I can at least see if the compressor works. Also does this sound like a no gas situation.

Sorry for the long post but really need to do as much of the investigation myself before taking to be re-gassed.

Ok so i'm going to answer my own questions. Guess I should have done a bit more investigating first. After reading a few more posts I went and checked the pressure switch which was ok. Followed back to relay. Bridged the connections and hey presto A/C now works. Incidentally the relay next to it that controls the thermo fan which is the same is also knackered. Hence why I've never heard it come on even on 42 degree days. So looks like I'll be getting 2 new relays tomorrow.

My problem is no air is comming out from the face vent or foot vent no matter which position i set it at air is just coming out from the front glass area onli

wats the go wif that

the thing is i got a guage in the side face vent so they must of did something to stop air coming out from the vents

i too am having problems trying to get my ac working too, just would like to know if with ac on does clutch engage and stay on and not come on and off like other cars, if that makes any sense. any help much appreciated

Thanks Rekin for the pics, you're a champ m8 ;-)

Mine had the exact problem as you've described. The servo arm dosen't move when I cycle through cold and hot. But when I wiggle the plug while doing that, the servo arm moved. So I tried taping up the wires, pushing the wires upwards, and all sort of other things.... but still have the same issue.

Eventually I was able to find a fix, the trick is to apply a slight pressure on the actual plug towards the right (back of the car). There is a rectangular void on the left of the plug and all I did was stuff some paper in there to create that pressure and the problem solved. I was able to get cold air again!! Bloody awesome. Thanks Rekin!

this is great info - i had similar problems where my air mix actuator for the foot area would get stuck & wouldnt allow me to go from cold>hot & vice versa.

when i ran my diagnostics the error in 'step 3' as per workshop manual appeared as number '34' which stated it was the air mix door that controls the foot area...i will try the piece of paper or zip tie trick to see if that works as the servo runs when it feels like it.

    • would a r34 gtr hood line up with gt/gtt stock fenders? after latch, front bumper and hinges are swapped for gtr ones? or would the fenders be too low or high in relation to the hood surface? ( I believe seeing somewhere that gtr front fenders use some type of riser for the sides, but do not know how that relates to stock gt/gtt fenders.)    
    • You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways. 
    • So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.
    • Damn that was hilarious, and a bit embarrassing for skylines in general 😂 vintage car life ey. That R33 really stomped. Pretty entertaining stuff
    • Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik
