hi guys

Just driving home from uni today and realised my feet getting really f*kn hot (My heater/ac was turned off), ive noticed it b4 but never took any action until now. I originally thought that it was heat from the engine travelling through the firewall but its not. The heat is coming from the outlet vents under the dash that heat ur feet when u have ur heater turned onto feet. wtf is this shit, y is it sending out heat when the heater/ac is turned off.

I think this is the reason y r32 dash board vents end up brittle and crack from this constant heat escaping.

If u turn off the unit when its on face the heat comes out of the top dash vents, if u turn it off when it on ur feet the heat comes the feets ducts.

any1 else experiencing this? can it be fixed?

Check inside temp sensor is connected.

Check inside temp sensor is connected.

It not usually the inside temp sensor it is usually the actuator at the back of the centre cluster (at the bottom on the passenger side) that gives up the ghost & stops reacting to the control signals from the climate system. Almost invariably it is a dry solder joint in there.

If you do a search you will find loads of posts on how to fix it. The downside is you need to remove the stereo etc from the console to get at it. The upside is it costs bugger all to fix.

Hey All,

I actually had the exact same problem in my R34.

I found that all the cabling was connected correctly and there were no faults.

I simply turned the Climate control knob right down to cool and no more heat on my feet.

Hope that helps abit.....

hey all, had this problem on my 180 and my cefiro... annoying as hell in summer, there is a thin metal actuator that dirests the flow of air either through your a/c evaporator or through your heater core, as the HVAC system pulls air from outside the car, it seems mine had pulled in some moisture and corroded this thin metal air control vent therefore constantly blowing hot air through the rusted out portion of my heater box. i only found this due to puttin a custom wiring harness to suit my stinger ecu.

probly not gonna be the same prob on all cars especially the new ones but thats what did it to my cars

anyone tried this yet?

yeah i have tried this... and yes it does work.

I have exactly the same problem as the one stated, plus my aircon only blows hot air even when turned on and set to cold... even though the hose in engine bay is ice cold when climate control is set 2 a low temp. im hoping the autoelec can repair it today. He said he thought it would be the actuator or the flap which switches it over from hot to cold.

but in the meantime i have been using this method of switching air con to recycled to stop hot air coming out when off.

Its because no amtter waht your aircon vents will push SOME air through into the cabin, evenw hen your aircon system is turned off. Just turn the aircon temp down to cold or recirculation. This has happened in every car I've ever owned, I guess its so the cabin still gets some form of airflow.

i have this prob also, if it is blowin hot air you can press the cold button on the climate control a few times when its turned off and the air will turn cool, its weird how it will change when pressing the buttons on a turned off unit ..

      After using a protractor for an actually accurate assessment of what is required,  and by NOT using my uncalibrated eyeball I worked out I need a 25° silicone bend from the TB ro the MAF, but, my choice was either a 30° or a 23° (23° is a weird spec), so I grabbed the 23° one from Raceworks I also grabbed 1mtr of 3" straight from Just Jap, I needed 350mm, but they only had 300mm, or 1mtr lengths....meh Also ordered a 1/2" hose bulkhead fitting from fleabay, this has a smoothish mushroom looking head (they are designed for below the water line of boats) that will fit inside the bend, the hose bit and threaded bit looks to long, but nothing that a hacksaw cannot fix if required, the hose will then just get jamed on the threaded bit up to the retaining nut Fingers crossed and the unsightly amount of hose clamps will be reduced down to 4 once all the parts arrive

      Oil change does not trigger code 21. Code 21 is for coilpacks primary side connection. You can try to clear the code with a battery disconnect, hold down the brake pedal to drain capacitors through the brake lights with the ignition on for 10-15 seconds before you reconnect the battery. I have seen R35 coil conversion permanently cause this code with no ill effects so it might be the resistance it wants to see isn't quite right on one or more coilpacks. Could be inside the ECU, could be the harness, could be a coil. You can test it all if you want or just ignore until the car actually starts misfiring.

      I forgot you have a Nistune ECU. Use Nistune to do all the tests I mentioned instead of faffing with 30+ year old electrical connectors. You can read MAF volts off that too, there are reference values in the service manual to tell you roughly what it should be in different conditions.

      No. I think it might be the AFM. Hence the use of the terms "swaptronics", which implies the use of swapping out electronics for the purpose of diagnosis. It's about the only way to prove that a small/niggling/whatever problem with an AFM or a CAS or similar is actually caused by that AFM/CAS/whatever. A known good item swapped in that still gives the same problem is likely to be caused somewhere else. They're all the same. Spraying AFMs with cleaner is an each way bet between cleaning it and f**king it.

      Can you mount the ATTESA pump in other locations?

      Oh wow! This might actually work amazingly. Do you know the ratio of the diff? I was told the only thing you need to make sure of is if the front & rear diff ratios are the same. Ours is a 4.083 Thanks!
