Hi guys, my car has no receiver dryer and no ac fan, and constantly pumps unstoppable hot air through the vents. I'm really not mechanically minded so could someone explain to me wtf is going on and how i can get it fixed cause i have no idea where to start.

have u checked that the switch for where the air comes from is not set onto outside air..U know the switch where u can change it from outside air to recirculating air already inside the cabin..

if u have it to outside air no matter if the a/c is off air will still come thru

vinnie is right, turn it on, and press recirculate so that the green (?) light comes on. let it change over to recirculate and turn it off. then never touch it again lol

yeah tried that, does nothing.

If the interior air sensor is disconnected you will only get hot air so my guess is that it will be either faulty or disconnected. If you find its connected try running the climate control diagnostic to see if its faulty. Common thing to find with your symptoms. The sensor is located on the center console facia behind where there is a small vent in it. Pull it off and you will see what i mean. If you need pics, i can arrange them.

i have same problem but i have aircon. I cant get it to recirculating. Would it be either the switch or the motor that powers the flap? If so, how hard is it to get to the motor?

Thanks

Sounds like one of your motors are dead. Either the motor which controls the hot/cold air or the face/feet/etc direction motor or both!

Try the diagnostic first to see what it tells you. The motors are located behind the dash and it requires you to take everything out to replace them.

Hi.

What Deren is referring to is the sensor which is behind the 4 slits located beside the ash tray. To check the sensor is connected remove the ash tray look and you will see the sensor on the right hand side. Locate the wires coming from it and if it is not connected fish around and find the other connector- you cannot go wrong as all the connectors only fit one thing. Hopefully this should fix the problem. If you have any work done to your car recently ie clutch or new stereo equipment it is usually the cause as professinals?? who do the work like to remove the surround which goes around the centre dash equipment and neglect to connect this or the cigarette lighter wires. Hope this helps.

There is another sensor located in the engine compartment on the firewall behind the engine although is not normally a problem unless you have been playing around in that area.

man, this thread has reminded me how hot R32 GT-Rs are when the weather is warm.

even with the vent set to recirc, the heat that comes through the firewall and floorpan when you drive it for a while is annoying

you could always try the simplest solution and see if all the vacuum lines are connected at the back of the climate control panel - don't laugh, I had the exact symptoms you described - checked everything they pulled the stero out again and found i'd knocked the lines off. 5 minute job and problem solved. i had added a new head unit.

My 32 GTR was the same - constantly blowing hot air, even with it set to recirculation... this thread helped me fix mine - http://www.skylinesaustralia.com/forums/R3...old-t93814.html :D

R32's dont use vacuum to control vents etc. Its all electronic with motors doing the work. Sounds like its actually quite easy to see the connecter as our12 described. Check that out. Good chance its the cause. If not its a good place to start anyway. Process of elimination.

behind the stereo surround/console theres a plastic line it hink its for the climate control.

i left mine off by accident once and it kept blowing hot air in, connected it back up and air was normal :P

yes there is the intake temp hose behind the dash just to the right of the air con panel,if that falls off or if you have pulled the dash out it blows just hot air

      Oh ok that makes so much sense. Thanks for clearing it up!

      And these modern "environmentally friendly" EV vehicles also run on the same smoke! When the engine, wiring, or batteries let it escape it also stops running!

      Mistakes were made, my R34 Story

      Yeah - I found the same information too.. 30% open is like 85% of flow etc. So it's probably going to be minor if not completely imperceptible. I also have a larger pod filter here, will swap that on and see if there's any difference. The hardest part is finding a place to uh, test this. It's quite noticable just how much having ducting to the otherwise completely open pod cools the intake temps down. It's better boxed, or shielded but driving for 30 seconds really makes it plummet to near ambient temperatures. I recall in the past when I was a RB land and had a nice flowing airbox -  - Then I took the lid off and put a pod there, and gained 9 psi of boost and about 60kw from the restriction I didn't know I had - with the controller at same duty cycle. However finding people using over the radiator intakes having similar KPA drops at WOT on built setups makes me think there restriction could be the exhaust or potentially the headers. Either way though, there's no real estate to play with and nothing that can realistically be done about it. The original dyno plot without the airbox, and the larger pod had a better curve. It was later I added the ducting and airbox, and a smaller pod to make it fit in there...

      That's not completely truthful now is it? Any flex fuelled factory cars also had the option to run on steam.

      Yeah so I guess your mechanic would know turnaround better than me....but I would have thought you had access to same day or overnight rack rebuilds there....any big city here in Australia has that service.   There are a couple of o-rings and seals involved, I guess the risk is the part is specific not general. Other option is if you can have it on stands in your garage for a while, steering rack removal is pretty simple (2 mounting brackets, 2 ball joints (separate by undoing the nut to the top of the threads, put a pry bar between the steering arm and control arm to put pressure on it then medium force on the side of the ball joint or top of the nut with a hammer to break it free) and then the trickiest bit is the splines to the steering rack (not too bad to undo, one nut then it slides out, but mark it first so you can reassemble it straight)
