1997 R33 GTR V-Spec - When the engine is cold and temp setting at 18c cool air comes out the dash vents. When the engine is warm or hot and temp setting unchanged it blows warm air out the dash vents (warmer than outside temp) If a/c is turned on for say 30 secs then off it seems to help but still is not same temp as outside. Anyone got any idea's ?

I had a similar problem check that your interior temp sensor is connected and working if not that will automatically go to hot. If its not that its prolly the tap that opens and closes to control hot water to the heater.

i had this problem too, its aparently a common problem on the r33's the motor that opens / closes the valve for hot / cold air is weak, and breaks after a few years operation, my car was doing it when i bought it so it was replaced under warantee, luckily, as the entire dash has to be removed to change it, well entire dash if its has a passenger airbag ..

at least this is what justjap in kirawee told me ..

the new motor itself is not expensive, just the time to do the work .. i remember seeing an article on howto remove the dashboard of an r33 - not sure if it was on this site - do a search, it was a red r33

cheers

the thing tang0 is talking about makes a clicking noise when you turn on your car... not sure if that has anything to do with it... try what Godzilla32 said... the interior temp sensor is just behind the plastic dash surround (that has all your stereo etc in it)... just below and to the left of your steering wheel you will see a small vent (horizontal lines) behind that there should be a black tube going to it and a plug with some kind of electronic component :D

Best bet would be to try the diagnostics on your climate control, withing 10seconds of starting your car, hold the off button on the climate control for about 5 seconds i think...

      Who has a Infiniti Q60, Q50 (V37)?

      By Duncan · Posted

      The ATTESSA is functionally identical to R34; there were a bunch of JDM models that continued ATTESSA including Fuga/Q70, Skyline/Q50, Cima etc as an option. All with Auto only and I think mostly for snow regions. AFAIK there were no AWD VR30DDTT sold in Australia - it is on my to do list to check regs for racing a LHD car in Targa/ATR/AASA/CAMS events because if I can get the auto to work it would be interesting to run a 4wd car The Ecuteck TCM tuning is the same model as their ECU tuning, they already have it for R35 and Dose's favourite, BMW. You buy "points" to allow your computer to be tuned, buy either a bluetooth (phone app) or bluetooth+USB+Key (phone and PC) dongle, and pay for a tune that will be locked to your tuner ( ). You can also access the tuning software yourself but 1. it is mega expensive and 2. these computers have a billion parameters that intersect, so how could you ever spend enough time on it to get a decent result.

      Or, is it a case of what it is like owning an R series Skyline? NFI what the previous owner has done or fiddled with... Ha ha ha After reading through this thread, I went on a bit of a research about the Q50/Q60. Now I'm quite intrigued by them! Is the AWD in them more like a WRX where it's always AWD, or is it more like the ATTESSA in the GTRs? By the sound of this TCU tuning, this sounds like a case of someone has made some real software for it, and you just need the right piece of hardware, and then you license that specific vehicle/TCU. Or is this a case of the software will be really expensive so only a few tuners have it, and you still have to pay a license per vehicle?

      By popular demand.. it was a coil. Got my hands on 1 new OEM coil, replaced with the one that made the less noise difference when I unplugged it while the car was running and started the car up. No stutter and the engine light was gone. I guess I’ll buy the other 5 they have lol

      No, code 21 is very straightforward. It can only be the things described in that diagnostic flow. In fact it has no way of knowing that the spark plug resistance is out of spec.

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.
