As the title says, yesterday morning my climate control in my r33 series 2 makes a *knock knock knock* noise when ever i turn the car on or change the mode the climate control is running in, i.e windows, to drives legs.

It sounds to me like plastic gears or something is clicking.

When i turn the climte control unit off an on again it usualy goes away, sometimes it clicks for 5 seconds, other times 20 seconds.

Is this a common problem?

Cheers

sounds like something is making the gears sticky, or blocking it, or the gears are slightly stripped. the clicking would be as it tries to change and it is just skipping the gears as it can't move them.

I ran the cable to my boost gauge down the center air vent, that was about 4 months ago, and its been fine since then, now all of a sudden its going it, could the cable have fallen into the gears or something?

Bleh i have to take the dash facia off on the weekend to install a din pocket and remove the hicas bulb so i guess ill try figure it out then.

cheers

It appears to come fron the center vent, where the boost gauge cable runs from, bleh just another thing to try and fix.

Hahaha if ONE single week went by when i didnt have to try cure a random noise in my skyline id die of shock.

If you do a quick search, it's been covered at least 8 times before that I can remember.

It's more than likely some sprocket thingy on the heaterbox. Mine does it, heaps of R33's do it. Sucks eh? =-]

You have to take the entire dash out to fix it. I myself could not be bothered doing that.

ahhh FFS!

I was hoping i would just be able to take the dash facia off to get to the problem, removing the ENTIRE dash is waaay to much effort, ill just turn the music up loud when i turn the car on.

bro, you need to replace the stepper motor in the aircon assembly...might be costly not really sure. my r33 made that noise before i bought it and said 'fix it!' asnd that what he said he replaced...

When i was looking under the dash today, i noticed down the bottom of the air vent a little black electric box which looked like something that could be causing the clicking noise.

If it is indeed that box thats causing trouble then it wont be hard to remove as is, ill try to get a pic of it.

mate i had this exact problem its a little arm joined onto some cogs (gears) what ever u want to call them after time the gears wear out but the arm still trys to move this causes the clicking noise it is big job to do specially for such a small part there is no way at all i could get this part out with out taking the dash out. I probably wouldnt have bothered fixing it but afew weeks later my heater core shit itself and i had coolant pissing inside the car so had to remove the dash for that anyway :laugh:

I just rang up a spare parts place to get a replacement motor and they told me there are TWO stepper motors for the AC! A higher one and a lower one. So..... seeing as noone here as differentiated between them (let alone mention there are two), I had to spring for both, cos I'm getting my stereo guy to fix it, and I don't to pay for him to replace one, only to find it's the other and that he has to go in again. One motor has 8 teeth and the other has 10.. or something like that. Both cost me $125.

      Ceramic turbine damage to engine - what did yours do?

      Ha, well, it's been.... a bit of a journey. Things have taken much longer than I'd hoped. I'll probably put up a thread at some stage. Hopefully soon. The car's not done any kms since my update in June though, put it that way.

      Here's the chart for fuel pressure vs. current draw, assuming your base fuel pressure is 3 bar and you run like 0.5bar boost on WOT, you should only momentarily hit 9amps here and there. (Ignore my prev post, I cannot read a chart these days it seems)

      Those comp test results are not hideous. Whether they are accurate or not (ie, when that comp tester says 140 psi, is the real pressure120, 140 or 160?) is unknown to us. The state of the battery used to crank it over is unknown, etc etc. Many people around here would say that the absolute values and the spread are perfectly fine to just add boost and keep going. I personally would be happier with a narrower spread than that, but even the diff between 125 and 145 is not terrible. That one cylinder at 125 though, has probably copped some damage relative to the others. You should inspect the valves seeing as you've got it open. Do you know how to measure installed ring gaps? That, and an inspection of the rings themselves, is how you will determine whether they need to be replaced. If you're not good to do these things, take the block and the pistons and rings to a shop that is, and ask them for the go/no-go on them. Do the bores need a hone at all? If so, you might well be justified in getting some different pistons in order to get away from the ring supply problem. Whether you're happy to spend a lot more money right now, on more gear, rather than less money, but an amount that looks stupid given that you will only get a handful of rings in exchange for that money, is for you to decide.

      Ok so i would love some advice here please, i purchased an R33 a few months back and its had a few mods done to the engine, its an RB25det running a Master ECU, 1200cc injectors, bigger turbo, oil cooler, oil filter relocation kit, Spool H-beam rods, acl/ross pistons. When i removed the motor from the vehicle (as its getting a respray) i thought i would compression test it and these are the following results. Cylinder 1-145psi, Cylinder 2-143psi, Cylinder 3-125psi, Cylinder 4-145psi, Cylinder 5-140psi, Cylinder 6-135psi this test was done with the motor on the ground and powering up the starter motor. I dropped the sump and found broken oil squirters on cylinder 3,5 and 6. I was told my rings are probably worn so i stripped the motor completely to get a new set of rings for it. The trouble is no one has these rings anywhere and they have to be custom made by Ross over in the states and will cost about $600+$200 delivery. My question is how can i tell if my rings are at fault and if they are still ok and is this price ok for a set of rings?
