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?

    • My idle is set at 950rpm though - Moving the timing around 20 degrees is not really what I'd call a calm idle. That said... neither is chop, by definition. The LS ECU likes to adjust timing to hold idle as opposed to air. It'd work, but generally speaking there'd be a discrepancy in the base idle and the IACV would want to move the timing around anyway to maintain said idle. I think I'm just going to keep the timing steady anyway. Preserve my engine mounts.  My aircon is now officially regassed. As the guy was reversing I noticed my reverse lights do not operate, along with my reverse cam. This is a bit distressing, because 100% of guides talk about which wire to connect to backup cams as "the goes with the [other color] wire". Often when doing conversions. Unfortunately the R34 colour wires aren't documented Unfortunately I had a T56 Magnum gearbox with it's reverse switch, which also isn't documented. Unfortunately there's definitely not documentation for people with both of these in the one car. Unfortunately I forgot. After many hours of this, I have a reverse cam and reverse lights again. The wire going through the trans tunnel to the reverse switch had broken. Upon inspection, it looks like this one wire had about 7 spade terminals and extensions in it.. for reasons I cannot possibly comprehend. I also spent the 750 hours required to clean up the wiring behind my head unit which now looks like this: This is a monumental improvement relative to what used to be there WRT triple gauges, head unit, traction control, wideband controller, and whatever the f**k OEM stuff still exists there in various states of connectivity/needed. Next step is to check in at the Exhaust shop to see/confirm how much clearance I have, to decide what mid mufflers or 'resonators' (which are just straight through, narrower mufflers) I can add and hopefully cut out a lot of exhaust leaks, pinhole, v-band or otherwise. But first step will be to 'take a look' before the next step.
    • Fark the AFM card and Nistune, Haltech Nexus S3, DBW, cruise control, flex fuel, dis dat.  
    • It's most likely the bolt/bush where the cover bolts back wore and allowed cover to move forward.
    • Still haven't put the injectors and R35 AFM in so we can tune the bloody thing for the HG highflow it got mid last year! I think I can forecast the upgrade path to a bigger twin scroll, external gate, Haltech, flex setup, Samsonas, dis dat, etc will be .... a while away!
    • Should have taken that opportunity to slot in a twin scroll turbo setup. Maybe next time.
