Has anyone found a fix or attempted to fix the dodgy climate control display in the R32? Mine operates intermittently but much of the time parts of the display drop out or jumble. It seems to be worse with high cabin temperatures but can play up any time.

EDIT: Just thought I'd bring up this old thread of mine as I've got my climate control apart on the table right now and would like to know if anyone has fixed one successfully before and if so what did they find.

I had this problem. Some buttons didn't want to work either. Pulled it open and cleaned all the contacts and switches and stuff with contact cleaner and cotton buds. Worked perfectly for about 2 weeks then the buttons went abit intermittent but she works most of the time. Display works fine though

mine has a tendancy to not come on when i start the car, btu give it 30seconds and it will appear and all the buttons / display works perfectly after that. this only happens occasionally.

my theory is a loss of charge overnight and a bad solder joint rendering it incapable of getting enough current initially when i start.

i dunno...

my screen used to garble and drop out on the odd occasion but i think the whole lot shorted out. i turned the ac off and while the screen turned off what actually happened was the fan set itself to demist and i could not stop it. the next day when i turned the car on it set itself to demist again. what the??? after a couple of days it seemed to fix itself. i drove to work with the ac on - no problem. i turned the ac off before turning off the car - no problem. when i got back in the car 6 hours later the whole cabin smelt like burnt plastic. ive since pulled the fuse for the ac and the smell is gone but ive had no ac for a few weeks now. ive had a brief look behind the ac unit and all the wiring looks fine - no melted insulation. will try pulling the control unit apart and see if theres any burns in there. if there is how much would i expect to pay for a replacement? apparently the r33 unit is the same as the r32 unit. if this is true i will buy a 33 unit as its newer.

yeah mine also is a little tendancy to occationaly work then not work, often with a quick tap on the screen it works again......very stange, thou must be a loose connection somewhere. I'm going to have to pull the unit out and check the soldering. Also whats the deal with the button on it which when pressed shows some sort of Japanese writting and degrees? is that outside air temp or wot?

Bit off topic sorry but alot of the funtions also didn't work when i bought the car on the climate control but they guy gave me a pile of parts which he thought were the stock amps or something, a bit off lookin around i realised that one was the computer at the back of the car which seemed to fix both the HICAS and the climate control when i plugged it in.

The little Japanese writing says ambient i think, but you should be getting the temp as well. Perhaps the sensor is not working? Dont ask me where it is though, i dont know.

Yeah mine has a few funny things with it.  First, a couple buttons don't always work.  Secondly, the ambient temp button used to display the actual ambient temp when i got the car, but now all i get when i press it is some Japanese writing.......  Any ideas?

I pulled the control unit apart to look for anything a bit sus like dry solder joints or dirty contacts. 3 screws and the face unclips. 2 more screws and the front circuit board pulls off.

It is connected to the rear circuit board by a row of pins that push through a socket in the front board. This connection might be where some of the problems are.

I took out the 2 screws at the back and pulled out the back CB (tight). It looked like it had been resoldered before so I tidied it up and put the thing back together. I ran it for a few minutes and it performed like new so far. Fingers crossed.

Just pulled mine apart last night. everything looks fine so maybe mine is a prob with the wiring. will take it to an auto elec after ive payed rego. will let y'all know what the problem is so maybe can save the rest of you some money if you ever have the same prob. just hope it dont cost too much.

I think the AMB sensor is on the top of the dash, left hand side, very close to the window. Well its some sort of sensor

Ambient sensor is at the front of the car on the factory thermo fan.

As for not working.

Done a FMIC lately?, and removed it maybe.

      3D printing fun

      By Sean'O · Posted

      Howdy friends, So another weird one today, I was looking into replacing some broken clips holding the front grille for the R32 GTR (part number 01553-03831), and noticed the brackets which are supposed to hold the grille in place were also missing 😑. I do recall seeing this issue many years ago, but didn't fix it at the time. A quick look on eBay and I was able to find the genuine brackets, along with all the screws which suited the headlights (part numbers 26042-08U05,26092-08U05). Happy days!....  Once they arrived however there was an extra nut in the packaging which implied that there should also be a bolt or a stud, and sure enough, after a bit of searching I found this thread from 2013, and @Ants clearly shows a stud should be present. Reading around a bit more, it's possible the headlights on my car are the "povo pack" headlights as mentioned by @funkymonkey in this thread way back in 2008. This could explain why the studs are missing on my set of headlights. Looking at the headlight diagram I wasn't able to see a suitable part number for the stud itself. The headlight did indeed have a recess that looked like it would accept a stud, but interestingly no thread or anything obvious how the stud would be affixed to the headlight, I suspect it may have been glued in, press fit, or melted into the plastic at the factory. Another member may be able to clarify if they happen to have a genuine set of N1 headlamps. The only thing we have to work with within the recess is a keyway which likely is there to prevent the stud from rotating within the recess. In any case, back to 3D printing, I put together a model which acts like a pug with a friction fit inside this recess, making use of the keyway so it doesn't rotate while tightening a bolt. Printing in TPU will allow it to slightly swell making a nice snug fit without cracking the part. I've designed the adaptor it to accept an 20 mm M6 bolt (stainless with a cap head in my case), as opposed to the standard M5 stud and I made use of the standard galvanised split washer that came with the genuine brackets from Nissan. Once the bolt and screws were all in place, giving the bracket a gentle shake gave the classic "shaking the car" feeling, very solid, which gives me confidence this is going to be able to hold on much better than the janky solution which seems to have been here for the past decade or so. Overall I'm really pleased with how this turned out and maybe there are more people out there running these headlights without a centre stud at all!

      R32 GTS (RB20DE) clogged cat

      By GabsReDeal · Posted

      Hey everyone, This is my first post apart of the introduction. I tried searching a bit on the forum but couldn't really get a straight answer. I got the car to my mechanic as I felt it being weak. It seems that it was missing on two cylinders due to the injectors. I had all my injectors clean and the car runs much better. The mechanic also confirmed my suspicions that the cat is clogged and needs to be tackled asap. The cat rattles a bit and the hot exhaust warning frequently lights up when driving after getting the injectors clean. In my introduction I was asked about what modification I might be interested in and mentioned a cat delete. From what I was told, this is not really beneficial on the RB20DE and there are more cons than pros.  Could perhaps anyone give some suggestions on what the best course of action would be since the current cat is toast and needs to be removed/replaced anyway? I can also sometimes smell a strong smell of fuel, but I'm not sure if this is related.

      When I was replacing my pump due to being stranded in the wrong state, I went with the Deatschwerks 320lph kit. It is a direct plug in to the stock wires, harness, everything. It comes with a plug... but you can plug the OEM plug directly into this thing. https://justjap.com/products/deatschwerks-dw300-fuel-pump-nissan-s13-silvia-r32-r33-r34-skyline-c34-stagea?currency=AUD Downside: Won't actually flow that much on boost if you want to push it on E85, but it's comparable to the 040/255 etc. Little more actually.
