Foznice, the same thing happens in my r32.

If I have everything off hot air will blow down onto my foot (accelerating pedal).... the air is hot to the point it almost burns my foot on long drives. If I turn the fan on it will blow the hot air through all the vents. I can't make the hot air stop no matter what I press.

If I turn my aircon on, it doesn't change, still blows hot air.... the only way I can get my aircon to work is if I keep my finger on the BLUE temp button to get it into Fast Cool mode.... then it blows nice cool air :P

Has anyone solved this problem???

Fixxxer :(

you can stop the hot air coming through when everythings turned off, by pressing the recirculate button.. seems to stop outside air (thats running over the engine) coming into the cabin.. It's a temporary fix but it should help until you can find the real problem.............

have all of you reconnected your reciever dryers? even if they're not gased it might help to plug them in as it's part of the system.

I regassed mine yesterday, it's not blowing air nearly as cold as it should be. I think this is partially because of the heater/airconditioner actutor.. it dosn't seem to be connected to anything (noticed when I took out the dash) and theres nothing I can do controlwise to make it move.. anyone else have this problem???

Hey Rylan

My R32 has been gassed twice in twelve months and it still blows warm air. Learned that a few days ago whilst driving up the freeway during the second hottest day on record :nyaanyaa::blink::huh:

Annnnyway, mine is terrible. I haven't looked at the actuator and until I saw this thread (re: thermisters) I thought I just had an aircon leak.

If (when!) I sort it, I'll post here.

Mark

thanks mark. I noticed something new.. I can get it to blow cold air.. by setting it to 18 degrees but when I give it some stick something opens up and I get the hottest air ever (and I found this out on a very hot day too :(:rofl: )..

I also noticed that if I put the climate control into 'full cold' mode it will blow the coldest air it can (not very cold, as I think I haven't put enough gas in) regardless of how much I give it.... just something to think about...

Mark, usually if the gasing has been done properly they put some dye in the system so that leaks can be found, the dye shows up under a certain type of light.. the guy that gased your aircon will probably have one.

Also, before it gets gased they usually hold the system under vaccum for about 5 or 10mins to see if there are any leaks... If this procedure was done, major leaks would have been found.... minor leaks might not show up though...

hi,

Im getting error 27-refigant temp sensor on my 32, will this affect operation. Also, the 3rd temp is about 4 all the time, should i just get a 2k resistor and whack in here, or, is there someplace i can get the real deal to fix it properally.

For the refigant temp, would i loose my gas replacing this one?

  • 2 months later...

Ok, I've done the whole diag check- got the 25 error code (sun sensor, I was under cover), and my temps were :

24.5

27.5

30.0

26.0

However, I continually blow one of the AC fuses (#8 in pic below) when I turn on the AC.

R32-Int-fuse-blk.jpg

The other AC fuse (#17) is fine, but I've replaced #8 fuse 4 times now testing- it only goes when I switch on the AC.

Needless to say I'm not getting any cold air, just ambient temp air blowing really hard..... :(

Any ideas??

thanks.

hmmm well I'll soon have a bit more time on my hands, So I've come back to this thread to finish my aircon saga....

I went to regas the AC a couple of months back, and it seems that it does have enough refigerant in the system, and the compressor appears to be working fine............ So my 'hot air' problem is from something along the electrics line...

So I did the test just before..

I again got the 25 error code - it's all good

and the negative 26... or "-26"... I believe this is the PBR from looking at the Dave's original post and the "sky is the limit" book which has a reference on the climate control diagnositcs...

Perhaps the negative is just supposed to be a dash?

I also noticed that I get the error code '34' when doing the actuator testing eg - the motor for the feet is having a bit of trouble... which would explaina the SQEAK SQUEAKKKK SQUEAKYYY sound that is always made whenever the mode of the climate control has changed... Might have a look at this too.

PBR by the way is apparently the hot cold engine/ambient air flap thingy.. Which completely explains why there's hot air come through all the time. Does anyone know if this 'flap' is vaccum operated or electrically operated? Because as previously mentioned, when I give it a bit of stick from first or second, I hear a little pop or thud, and then hot air comes flodding in... My mental picuture was that the little pop/thud is the flap opening. So perhaps if the flap was vaccum operated, and there were leaks in the pipe or something, maybe it could be effected from the engine boosting???

Maybe it's just the acceleration of the car that's throwing the flap open - I've acutally seen the flap so I have no idea if this is possible or not...

But yeah these are my thoughts... I will be taking apart the dash next week to get to the bottom of all this, I'll try and include some photo's too.

From the small amount of research that i have done on my aircon problem i think i have found why it is continually blowing the fuse, like daveharvey.ca.

Someone said that the magnetic clutch in the aircon compressor is drawing too much current and is shorting the fuse many people have had sucess with getting it respun, there are a few threads on here about it.

If anyone finds any other way of fixing this please let me know.

Thanks

I attempted this test just then in my r33 and it will give me the inside and outside temps, but it wont go further to give me:

air intake > (before evaporator temp)

refrigant temp.>( evaporator temp)

When my aircon engages it draws wayyyy to much power from the engine and makes a kinda cough sound. Ive been in my mates r33 with the aircon on and you cant even tell its on....

My air con doesnt blow COLD and the heater only blows slightly WARM.

I enter the test mode and get 25 (In my shed at night)

Flashes 3 for a few seconds then 30. (Whats this 30?)

Outside 35.5 , This is too high?? Same as when I press the AMB button i get 35.5 (Its definately under 20 outside)

Inside 18,

air intake 17

refrigant temp 15.5

Any ideas? The only problem I can see is that 35 degrees outside is totaly wrong?

I would have thought that the Aircon Would probably more seeing as though it thinks its so hot outside?

    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
