Hey guys, a whirring noise has just started coming from the air con, sounds like a lawnmower in my dash. Well, maybe not that loud :P . Does this mean the a/c motor is on the way out, any ideas on how much it would cost to replace this, or does the whole a/c unit need to be replaced? I imagine it won't be cheap either way.

Cheers.

i had the same problem, had paper (wtf!) caught in the fan, it was easy to get out though... (mine is a R33)

just remove the kick panel on the passenger side footwell left wall, remove the ECU, unscrew the 3 screws holding the black cylinder looking thing up into the dashboard, and gently pull it out, it houses the fan.. clear it out and stick it all back in :D 10 minute job, and i put of with the crappy noise for months!

good luck!

does your aircon work popperly? producing cold and so on.

could be the a/c compressor that is getting weared out. so remove the belts to get to a/c compressor belt and remove it too.

then turn it by hand it should turn smoothly with out any odd sound and you should also press and pull on the pulley in all directions, you are looking for clonks and wiggling. if there are any your compressor needs to be changed

Still seems to work ok, just the noise that's annoying. I'm getting my 100,000 km service done next week so I can get my mechanic to check those things out, hopefully it's just a belt or something not too serious.

yep, sounds exactly like what mine has been doing, on really hot days it would struggle to keep the car cool though and i have to turn it off after a while and back on again and it starts cooling.THis was happening for about two weeks and on friday it blew up!! It started blowing hot air, then there was a burning smell and a bit of smoke from under the bonnet, I turned off and the smoke and shit went away. So now I'm without air con and it's really ****en hot. Hope this can be fixed easily. Hope yours doesn't blow up!!

i got the shits with mine and bought a second hand compressor anyway. cost me $200 but its worth it. didnt have a chance to fit it though, front brakes locked up at 100km/h and i hit a parked car, but hey, atleast now that i got the motor out, makes the compressor swap easy :P

      To add to that very useful summary, even in the race/rally r32 gtr I have good quality, new(ish) poly bushes everywhere because that is what rules require, and the handling is excellent. Of course, the car doesn't do many klm but I'd still expect poly bushes to last better in road use than sphericals (especially as I have a couple of klm of dirt road to stuff sphericals up) I would change the front upper arms to spherical if I was allowed to, because the poly bushes flog out often, but otherwise new bushes (and ball joints) and a good alignment can make a world of difference

      Any chance you can get a Nistune board installed instead and set the speed limit to whatever your tires can handle?

      ER34 AT ECU and HKS SLD pins

      By GoHashiriya · Posted

      Hi all, I need to get this HKS SLD attached to my stock ECU because I've now got the German autobahn and faster European circuits to contend with.  The car is a manual 2dr ER34 with an AT ECU and I've realised the AT ECU has two pins for speed sensor signals: Pin 29: Vehicle speed sensor signal (Vehicle speed sensor 2) Pin *58: Output shaft rotation sensor signal (Vehicle speed sensor 1) - *RB25DET A/T model only Before I go butchering this harness, is anyone sure of which pin is the correct one for signal adjustment? The attached document from HKS indicates pin 29 but I found this situation mentioned in the following thread on a different forum (R34 GTT Auto Trans Speed Cut Problem | Zerotohundred) mentioning pin 58 needing to be altered by member zephuros, albeit it seems to be for an RSM-GP and the info appears to be old.  R34_All_Workshop_Manual-pages-2.pdf R34_All_Workshop_Manual-pages-3.pdf R34_All_Workshop_Manual-pages-1.pdf HKS SLD Vehicle Pin out P59-P70 ER34-pages.pdf

      Slimline sub on the rear parcel shelf is doable. Pioneer TS-WX140DA is only 70mm high.

      People like Johnny Dose Bro might be laughing at my post because I accidentally added 100mm to my numbers. 350-355 is indeed the lower limit. 450 is off-road Skyline spec.
