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

      Good tips, will get on those tomorrow. When doing the maintenance I did move a few of those connectors around, and things that are old tend to not like moving around. (Like me).

      Don't try it. It will be shit. Better chance of damaging the engine than gaining any knowledge about the old one. Maybe, but unlikely, especially if the O2 sensor is working. You can use NissDataScan to look at the stock ECU.   Cleaning the AFM is seldom necessary and seldom helps. The R35 coil & loom conversion should eliminate dud coils or plugs. But as you still have misses - look to the plug where the coil loom connects to the engine loom, and the CAS plug. Need quality connections there. Also look to injector plugs. And the AFM plug while you're at it. Also look to whether your injectors are clean and flowing evenly. Get them out and onto a testbench.

      Good to know, I feel like I am in for a rollercoaster ride that looks like a sine wave.

      Hey folks. I've been lurking and browsing the forum for a while, since I got into my head that I wanted a skyline. Having purchased an overpriced completely stock GTT, (only "mods" it has is HKS pod filter and catback) now that it became legal in the US, it was all glorious and sututu noises here and there. But then I wanted to do things right and went to do basic maintenance. After all the fluids, filters done, I did the spark plugs, that's when the problems started.. First the car started spluttering at around 4.5k RPM. Which I gapped down the new plugs and that solved the sputter there, but the car now always misfires at idle with pops when lifting off and shifting 2nd to 3rd. Similar to the issues in this recent thread. I've been banging my head against the wall, reading the threads here and trying suggestions for a couple months now, so decided to start this one to explain exactly what I tried and what is going on. The symptoms of the issue: Idle and low revs misfiring intermittently. You can hear the exhaust tone change and the shakes on the shifter knob. It happens frequently, but doesn't seem to have a rhythm to it. Pops when backing off throttle. It pops and or burbles almost feels like it spits fire when it pops. (Happens mostly in 3rd gear at around 2k RPM). When under load and after 6k RPM, it also pops when shifting from 2nd to 3rd. There's a ticking noise at around 2k RPM in 2nd gear going downhill, seems unrelated though but I am out of educated and downright dumb guesses. Not noticeable lack of power when putting the car into load. The attempted diagnosis and solutions: Unplugging coils when the car is running This did nothing to change the idling and tone shift for every cylinder. Checking the exhaust headers with thermometer They all are within what I'd say it is margin of error of the laser thermometer New spark plugs Tossed two new sets, copper, iridium and using the old ones, still misfiring, even re gapped to 0.8mm, still same thing. MAF cleaned with the "specific" spray cleaner No changes in the issues what so ever. Brand new loom and r35 coil conversion (was going to add the r35 coils anyway) car runs arguably better, still misfires, but seems like does less frequently. Placebo? Code 21 now being thrown, thanks nissan gods. Removed the CAS to check the shaft for play or anything. CAS seems all fine, nothing that indicates any issue, visually speaking. Things to attempted next: Ordered a new MAF (chinesium from Amazon, to be able to return regardless of result). Fuel with proper gas, maybe it is this California water that they sell as gas that is to blame? Plugin the link ECU and check the info using the built in base map. Go back to BMW and eat my rob bearing breakfast without milky oil mixture.   Do any of you have experienced anything like this or have any suggestion?
