Hiya guys i got a bit of a problem....

When i turn on my car or if my cars on and i turn on my climate control, there is a slight knocking sound coming from behind the unit inside the dash. This lasts maybe 10-15 seconds but everything seems to be working fine!!

Any1 else had this problem or know what it might be?

Cheers

had the same sound as well. i suspect that it could be the internal vent opening up to allow air in. i usually circulate the air inside the car when the A/C is on but when i turn it off, i noticed wind still blowing in when the car is moving and i realised that the vent has opened up to allow gushing air.

may or may not be...

yeah, there are two relays (motors) which slide open the vents in the heater unit to control between the aircon and heater to give your xx degrees. If one is slightly dodgy, it may make that ticking noise - its like "slipping" on its catch.

Its no biggy, most skylines seem to do it to some extent. It doesn't worry me..

This is the problem.. that black thing ontop is one of the relays (there is another on the side of that box) that slides back and forward to open the vents in there. If its slightly stuffed it will "click" when operating.

you could buy my heater box for $40.. it has the relays on it. Then you'll have to pay somebody to pull apart your entire dash to the firewall (or do it yourself) and replace these components, which is about a 6 hour job.

you still want to fix it?

Hello predetor. Yes i do wona fix, i fkn hate that sound and sick of punching the **** out of the dash hoping it stops. OK so you have this part called the 'heater box', if you are mega positive that the noise will stop, then yes I will definetly buy it. How big is the part and how much is shipping, as I am located in melbourne, I am going to get it installed for free from my mechanic, so not a problem.

I got the same prob too...

The way I stop it (temporarily) is push the ^ button once (to turn temp up) then the v button a few times (to turn temp down)

you can do this with the unit on or off doesn't matter, and it stops it for a little while...

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.

      Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.

      Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
