Hey

Just picked up my R32 today, more than happy with it.. but the heating doesn't work, and it is winter at the moment!..

The fan and all the different modes work, like feet, face, and fan speed, 1,2,3,4 etc

A/C works and all that other stuff, but no heat, it just blows cold air.

Any ideas what it would be, I got no idea and don't know where to start looking.

Any help would be appreciated. >_<

Thanks in advance,

Abu

Hey mate, I recently had the same problems your getting. First of all, try holding down the heat button for about 10sec or until an sign 'FH' appears on the screen. It should overide all the sensors and push out as much hot air as it can. Make sure the engine is warm too. :) Give that a try and if it still doesn't work then I think it could be something to do with the motor which controls your hot/cold air.

Let me know.

Hey man

Thanks for the info.

When I held down the heat button the FH symbol did come up but not hot air came through the vents, stillt he same cold air.

Car was warm, and I left it on for a while in FH mode, but still didnt work..

Will look into it further on the weekend when I get some more time.

Any one have any more information or past experiences with this?

Thanks,

Abu

Sounds like you have the same problem I had. Try doing the diagnosis to see if there are any other problems. Shouldn't take long and it'll show you what's wrong. If not, it SHOULD be the problem I was having.

As Adam said, it sounds like the motor controlling the door which controls the blend of hot and cold air. i was having the same issue, so i pulled the dash out and made the easy diagnosis. I Replaced the motor with a second hand one and now i dont freeze on the way to work in the morning. Feel free to pm me if you need a hand.

Damn dash out!! Stuff that, I hope its not that serious.

I will see how I go with the diagnosis and then go from there. Thanks for the offer of PMing you if I have any issues, will definitely take you up on that!

Thanks,

I think you can replace the door motor but just removing the centre consol section where the stereo is, but if it ends up that the motor isnt the issue you will probably have to take the dash out anyway to work out where the issue is. The dash out job is pretty easy anyway once you have done it before.

Are you sure you have to take the dash out to replace the motor though? I remember when I was stuffing around with the motor to try and get it fixed, it didn't seem to hard for it to get out from where the passanger's feet go.

How long did it take you to remove the dash R324DR? I hear it's about 6 hours!

Go on to Page 3 of this "General Maintenance" subject, and there's the same subject ( about 20 posts, I think)... May help, and shortcut doing it all again. Have you tested it after a reasonable distance. Takes a while for hot warer to circulate thru heater radiator.

Hey

Thanks for that, will check that thread now.

Yep, done it over a fair distance, tried it over 30kms of driving lol

like is said, i think you can replace the blend motor by just taking out the centre consol part (sterio, ash tray, climate control unit, gauges (if GTR), plus side sections). If your in a hurry the dash should only take about half an hour to an hour to take out. Will take longer if you have no experience with removing car interiours, but no where near 6 hours.

make sure the heater isnt bypassed in the engine bay, this can be done when the heater core starts leaking.

Thanks man. Checked that one already :D

Will bleed the cooling system as well, might be an airlock in there causing the heating not to work.

Got some free time today so will run the climate control in that diagnostic mode and see what it brings up in the error table!

Thanks,

Abu

      I've heard the Tomei USA head gaskets are decent if you want to o-ring the heads but otherwise not recommended.

      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
