R33 Climate Control knocking PLZ help!

[ABuSD]

Hiya guys i got a bit of a problem....

When i turn on my car or if my cars on and i turn on my climate control, there is a slight knocking sound coming from behind the unit inside the dash. This lasts maybe 10-15 seconds but everything seems to be working fine!!

Any1 else had this problem or know what it might be?

Cheers

i have the exact same prob, i think its a relay

it doesnt effect how my climate control works so im not worried about it

[mexr]

Not a problem, comes and goes, my mechanic told me the replacement part is like 5 bucks, but labour will be a lot. Thus no point worrying about it.

[ABuSD]

LOL thanks guys!!

Yeah i got same state of mind about it if its not doing any harm leave it!

Mexr: thought it would b the case, cheap part, killer labour!

I got the same problem too... very annoying but not annoying enough to pay for

[SHY33]

Also have the same problem.. seams a common one.. "tunk tunk tunk" something like that anyhow.. I believe it may have something to do with the position of the flow.. ie: Vents, floor, windscreen.. Anyhow it is damn annoying noise i know that!

after it stops when i first start the car, it doesnt do it anymore unless i try to use the windscreen dimister. then it comes back for several seconds.

I think its something to do with the vents (when the vents change position

I've got the same problem as well, when I first got the car it happened then stoped for a couple of months now it's back again.

[ABuSD]

LOL seems like it is a common problem!!

If any1 fixes it let us know!! Ill do the same!

Cheers

had the same sound as well. i suspect that it could be the internal vent opening up to allow air in. i usually circulate the air inside the car when the A/C is on but when i turn it off, i noticed wind still blowing in when the car is moving and i realised that the vent has opened up to allow gushing air.

may or may not be...

yeah, there are two relays (motors) which slide open the vents in the heater unit to control between the aircon and heater to give your xx degrees. If one is slightly dodgy, it may make that ticking noise - its like "slipping" on its catch.

Its no biggy, most skylines seem to do it to some extent. It doesn't worry me..

ditto - I had the same problem on my GTS. I learned to live with it (for 2 years!), it doesn't seem to affect the system functioning...

I was told fixing it would involve stripping half the dashboard apart, something I couldn't be bothered to do.

[predator]

yeah, it does.. this is the part you have to get to (the one in the middle)

Thanks for the pic predator, think I might be leaving that one alone. hehe

This is the problem.. that black thing ontop is one of the relays (there is another on the side of that box) that slides back and forward to open the vents in there. If its slightly stuffed it will "click" when operating.

I have this problem too! i fkn hate it. first i tried punching the **** outa the dash, obviously didnt work. What is the parts name that i need to replace??????????????????/

im fkn sick of it, if any1 knows, tell me so i can replace it. or if any1 has it. URGENT, AS I NEED TO SELL MY CAR AND CANT!!

THANKS

[predator]

you could buy my heater box for $40.. it has the relays on it. Then you'll have to pay somebody to pull apart your entire dash to the firewall (or do it yourself) and replace these components, which is about a 6 hour job.

you still want to fix it?

[NickySantoro]

Hello predetor. Yes i do wona fix, i fkn hate that sound and sick of punching the **** out of the dash hoping it stops. OK so you have this part called the 'heater box', if you are mega positive that the noise will stop, then yes I will definetly buy it. How big is the part and how much is shipping, as I am located in melbourne, I am going to get it installed for free from my mechanic, so not a problem.

[Zahos]

I got the same prob too...

The way I stop it (temporarily) is push the ^ button once (to turn temp up) then the v button a few times (to turn temp down)

you can do this with the unit on or off doesn't matter, and it stops it for a little while...

[NickySantoro]

ahh ok.. well that will help, but i prefer to get it repaired... Predetor??
