Seen a few things about this sort of thing, just check all the fluids of your car (coolant, power steering fluid, all of them) and make sure they are all okay. But from what I have seen before it is one of these:

1 - When the car is first starting, it is just the lines filling up quickly & it makes that sound.

2 - There may be a problem with the heater core, otherwise I would say it is an air con problem somewhere else. Just make sure your car isn't leaking coolant either, it *could* be the start of an engine problem.

When it makes the sound just check to see if there is a smell coming from the vents, that could lead to the answer too. Good luck with it, hopefully this dosen't effect the car itself.

Edit- Just read the first post properly lol, that it isn't with the engine running, so it seems like the heater core, so focus on the AC more than anything, but double check with the fluids anyway.

cheers for the help mate, seemed to of stopped it today might of just been a one of, i would say it is the heater cos i turned it on on monday night for the 1st time since i had the car and it made that noise then the next morning and night, but its seemed to of gone away for now

My car clicks too from the climate control vents. CLICK CLICK CLICK CLICK. My mates n/a R33 had the same thing too. It comes and goes, gets a bit annoying. Any ideas?

im rippin me dash of on the weekend to paint it again anywyas so ill see if i can dr karl it myself and let ya now what i come up with

a mechanical clicking from behind the dash when you turn on the ignition could be a fault with one of the vent solenoid drive mechanisms. i have this problem with my car depending on how the climate control zones are set. from what i can gather its a common problem with the 33's... do a search you will find a few threads about it.

if this is your prob then i have read its just easier to live with as you have to remove the entire dash to get access to replace it.

my noise from under the dash is like a vacuum motor that's doing it's thing ( opening or closing a vent), does it occassionaly when the air is on, I think. Hard to describe the noise, definitely not a clicking sound, more like a squelching noise. It's not that annoying but would be better if it wasn't there. Don't notice it when the music is up loud.

F****** driver door window stuck 3/4 way up today. Can hear a clicking sound within the door when switch is operated. Could be the motor is jammed. Any clues?

    • Also had a look at the Nissan JP website looks like the 400r has a slightly shorter ratio than than the regular V37 3.133 VS 2.937 which from a guy who has driven both 3.69 vs 4.11 ratios in the S15 is bugger all. Seems that the AUTO Z runs the same ratio as the 400R but can't find any info as to if its an open or LSD? More often than not the auto LSD is open
    • Do not replace the power steering lines with this stuff. If it's anything like the Chase Bays stuff it will leak and be worse than stock. The reason why the reservoir is on the LH/passenger side of the car is because that's just where the reservoir was most convenient to fit. Don't overthink this stuff. The intake/cold side of the engine is pretty busy on these cars. And again, the hardpipe is designed to be a janky power steering cooler. In theory you can replace it with a real power steering cooler but that's really only for track use where boiling the fluid is a distinct possibility. Start with the low pressure lines feeding the pump from the reservoir. Make sure there isn't a bunch of junk in the reservoir filter. Be careful to not get ATF all over the engine bay. I hate dealing with ATF spills, you can clean it up and the slightest crevice will still release more oil that can still drip over time. You also want to inspect for leaks before you make a mess and can't tell what happened. Most likely you have a leak somewhere that is allowing fluid out and air in. Failing that it's allowing air in but not fluid out. Only place I can really see that happening is on the low pressure side because the pump will pull a slight vacuum to draw fluid in. Everything after the pump is high pressure or lower pressure, approaching atmospheric by the time it returns to the reservoir.
    • I did a skidpan night at SMSP this week, it was much cheaper than $350. But yeah, you need to slap an LSD in that thing.  I put an OS Giken in the 370Z and it's f**king MARVELOUS even compared to Nissan's viscous LSD. So you're saying it's free now that it's a housing estate? 😂
    • Nah, the car seems to run exactly as it did prior, in saying this it does "seem" to be better down low, like more eager to rev, but that may be 100% placebo effect from intake noise But, I'm not worried about it at all, in the end it is a fairly low compression NA engine that has a well shrouded intake,  if it is getting hotter IAT I cannot notice anything negative performance wise from the seat of my pants thrashing it about on the street or sitting in traffic, so meh, car now now makes induction noise so I'm happy
    • Do you have an IAT sensor? It's worth checking it to see. You may be suprised how little gap you actually need to flood your engine with hot air. (I tape up my airbox for a reason) :p
