Hey all, my r33 gtst has hot air coming out at the feet constently thru the air vent. I also have a ticking sound that goes for about 5 seconds then stops from somewhere inside or near the aircon/heater in the dash when i change the positions on the climate control. My a/c dont work cos the belt broke a while ago so i cant use that to even it out, and i think it may need a new comp. It comes out pretty warm to, i can put up with it in the mornings a 5am going to work but not on the way home, i must have the windows down to let cool air in. Has anyone had this problem or know how to fix it. The ticking sound sounds like its plastic like the old days when you would put the plastic on ya spokes of ya rim to make the sound oon ya bike. Ive been told it could be solinoid but its not that type of ticking.

Please help me someone or give me advice anything will do at the moment

the ticking noise is the adjustment cog in the aircon,when you change the vent settings it moves to change the flaps and what happends is some of the teeth get striped off the wheel over time and then it just skips around in the same spot until it realises its not getting anywhere then stopes.

have ether of you had your dash out latly? there is a tube that goes to a small vent in the dash that has a small sensor it it,it uses this to work out how hot or cold it is in the cabin and then regulates the temp.if this is not connected it just defaults to max settings so you will only ether get full hot or full cold no matter how much you muck around with the temperature settings.

the hot air comes out from the feet always. press the button on your dash that looks like an arrow and your hot air will stop coming in... as for the clicking the cog inside the dash that adjusts it all has worn out and slips making a clicking noise.

Yeah ive had the dash out before but didnt notice it till a bit after i had done it, i might rip it out and have a look if the sensor is connected properly. The teeth slipping sounds about it, bugger it, how do i fix that, where is the best place to take the car to get that fixed up even, any1 know?

I get the air at my feet all the time too in my R33, It's always what ever temp I had it set on when the Climate control was on, so I was was running it on 18 with AC it would come out cold when I turn the climate control off, if I had it on heat 32, it would be hot when I turn it off.

I get the clicking noise to when I turn on the ignition and when I change the blower positions on the Climate control, fcking annoying lol

Take it to an auto electrician to have a look,

From what i understand of the stripped cog scenario, it is possible to just replace that part but the cost is up there, whereas replacing the whole thing is up there too either way the whole dash has to come out just to get to it.

mine hasnt f**ked up yet... knock on wood. the part itsself costs nothing its the labour to get to it and replace it. if youve removed the dash before its something you can do. as i said with the hot air coming from your feet thats normal. just set it to recirculate air and it will shut the vents.

Yeah ive had the dash out but damn wasnt it a pain in the arse, i ended up cracking the bloody thing an i look at it every time i jump in for a drive, its a small crack but i know its there! It must be a skyline thing, i may have a go at giving it a fix myself before summer comes round and also gotta get the a/c fixed by then. Why would they be made for hot air to constantly come out, it seems bloody strange to me

      Cheers. Skyline is back on the menu, can’t get rid of it. It’s like a child you don’t want, or herpes

      I got back to Japan in January and was keen to get back on track as quickly as possible. Europe is god-awful for track accessibility (by comparison), so I picked up a first-gen GT86 in December just to have something I could jump into right away. The Skyline came over in a container this time and landed in early January. It was a bit battered after Europe, though—I refused to do anything beyond essential upkeep while it was over there. The clutch master cylinder gave out, and so did the power steering. I didn’t even bother changing the oil; it was the same stuff that went in just before I left Japan the first time. Naughty. Power steering parts would’ve cost double with shipping and taxes, so knowing I’d be heading back to Japan, I just postponed it and powered through the arm workout. It took a solid three months to get the car back on the road. Registration was a nightmare this time around. There were a bunch of BS fees to navigate, and sourcing parts was a headache. I needed stock seats for shaken, mistakenly blew 34k JPY on some ENR34 seats—which, of course, didn’t fit—then ended up having the car’s technical sheet amended to register it as a two-seater with the Brides. Then there’s the GT86. Amazing car. Does everything I want it to do. Parts are cheap, easy to find, and I don’t care what anyone says—it’s super rewarding to drive. I’ve done a few basic mods: diff ratio, coilovers, discs, pads, seat, etc. It already had a new exhaust manifold and the 180kph limiter removed, so I assume it’s running some kind of map. I’ve just been thrashing it at the track non-stop—mostly Fuji Speedway now, since I need something with higher speed after all that autobahn time. The wheels on the R34 always pissed me off—too big, and it was a nightmare getting tires to fit properly under the arches. So I threw in the towel and bought something that fits better. Looks way cleaner too (at least to me)—less hotboy, less attention-seeking. Still an R34, though. Now for future plans. There are a few things still outstanding with the car. First up, the rear subframe needs an overhaul—that’s priority one. Next, I need to figure out an engine rebuild plan. No timeline yet, but I want to keep it economical—not cutting corners, just not throwing tens of thousands at a mechanic I can barely communicate with. And finally, paint. Plus a bit of tidying up here and there.

      Nope, needed to clearance under the bar a little with a heat gun, a 1/2" extension as the "clearancer", and big hammer, I was aware of this from the onset, they fit a 2.0 with this intake no problems, but, the 2.5 is around 15mm taller than a 2.0, so "clearancing" was required  It "just" touched when test fitting, now, I have about 10mm of clearance  You cannot see where it was done, and so far, there's no contact when giving it the beans Happy days

      It's been a while since I've updated this thread. The last year (and some) has been very hectic. In the second-half of 2024 I took the R34 on a trip through Germany, Italy, France and Switzerland - it was f*cking great. I got a little annoyed with the attention the car was getting around Europe and really didn't drive it that much. I could barely work on the car since I was living in an inner-city apartment (with underground parking). During the trip, the car lost power steering in France - split hose - and I ended up driving around 4,000kms with no power steering.  There were a few Nurburgring trips here and there, but in total the R34 amassed just shy of 7,000kms on European roads. Long story short, I broke up with the reason I was transferred to Europe for and requested to be moved back to Japan. The E90, loved it. It was a sunk cost of around EUR 10,000 and I sold it to a friend for EUR 1,500 just to get rid of it quickly. Trust me, moving countries f*cking sucks and I could not be bothered to be as methodical as I was the first time around.
