I have a problem with my air con, it only blows out cold air when set at 18 degress. As soon as you adjust the temperature to 18.5 or above it changes to the heater setting. It stops blowing out cold air and starts to blow out warm air.

Has any one had this problem before? know what is causing it? or knows how to help? :action-smiley-069:

Ok....hope this helps...I had the exact same problem..cold air at 18...then when 18.5 or 19 onwards it gets warm air...never really bothered me...until one day...was looking into my front bar...underneath the rego plates...there was a plug that was UNPLUGGED...didn't really know what it was but plugged it back to a socket around the same area...and what do u know....a/c climate control works fine now! It also used to automatically change the blowing mode all by itself...but after plugging tht plug back in...everything has been fine! Try it out and see if tht plug is unplugged...

when the alarm was being installed i noticed black plastic tube no wires, asked installer what it was, he advised thats for climate control and plugged it back in...he advised he didnt unplug it. is that all it is or is there actual wire connector???? thanks in advance if anyone can confirm this! also got a flashlight and shined it into little grill.... there nothing there besides a small metal wire and round plastic surround... maybe there is no sensor in there already!

      Manual Shifter slightly bounces/moves/vibrates when accelerating/deaccelerating

      By Duncan · Posted

      Congratulations on your find  Did you mean it has 6k miles or was that a typo? Firstly, keep in mind some movement of the shifter is normal...it is a long rod hanging out of a box bolted to the engine. Having said that there are 2 next places to look: 1. Transmission and engine mounts. If these are worn or broken the shifter will move around more. They are reasonably easy to source and replace on a hoist, and possible but uncomfortable to replace car stands 2. On the bottom of the shifter there is a nylon cup that sits over shifter's ball end. If this is worn or broken the shifter will move around more than it should (but will still shift OK). That is a cheap part and requires removal of centre console, rubber shifter hole covers and a circlip in the gearbox shifter hole to remove the shifter. Re maintenance, as with any new import you should change all the fluids including transmission when you get it; never trust the seller and previous owners to have done the right thing. I am pretty sure R34 GTT is the same as earlier big box transmissions, so use any good quality GL4 75w90 trans fluid if it is shifting well (if it is hard to shift due to synchro wear, redline shockproof lightweight will keep it alive a bit longer before rebuild is required)

      Misfire/stalling issues

      Well considering I have the exact same problem with that as the original one I don't think that the ignitor is the problem. I would imagine that this being such an uncommon problem the possibility of getting a new ignitor that is bad in the same way as the old one has to be very slim. I'll definitely pull everything apart this weekend and check the turbo out. Got quite a bit of things to check out Saturday like fuel pressure and the pcv so I'll report back once I do that.  Thanks everyone for all the replies this is all really helpful

      Rb's have issues with bottom end starvation, not head starvation. Which either way, you probably wouldn't ever see on a dyno. Strange... What's pump gas for you? Octane rating?
