you can buy horns from most car shops (whether good i dunno, i want a truck horn :p) all ya need to do is locate your horn (ussually just behind the front bar) unplug (should be a single positive wire one) take off bracket mount new horn, plug up positive wire, negative just realies on your chassis being earthered.. simple mod to do :p

did it to my past 2 cars :D

The horn in the turbo is awesome

I would've thought they'd be the same thoughout the range :confused:

I remember the horn in my Barina... I'd almost hang my head in shame if I had to use it

ur going the wrong way about it... why nurb stickers then? paint it red, slap numbers on the side, and weld the doors shut so you can only enter from the window :p



just buy a set of air horns or something pete? only question is, can they be hooked straight into where the std one is to save having to rewire everything...

from the horns ive seen, just a simple power and earth so you can pretty much retrofit any horn into it!

Not sure about CDTi's but my CD already has a second harness to hook up the second horn, all i need to get is the second horn and a double brackett from Holden parts.

My horn is very loud and F**K off ish. Maybe have a look around the wreckers for some dual horns off of a TS astra.

Word of warning to Horn changers... It IS a simple change if using a STANDARD type horn as they draw low current.

IF you are going to fit AIR-Horns, you will need a relay that is powered by the old horn wire, otherwise, the next toot you give someone will weld your horn switch together & we all know what happens then...

Bonnet up & wires gettin yanked...

Do it the right way, save yourself some major embarrassment...:D

also you'll get defected if u dont have a plain horn as a novelty horn they dont class that as a warning device so your better off setting it up to a seperate switch ;)

Do u defo know the horn is fine??

Pull the horn out & hook up 12v across it.. Either way shouldn't matter...

If thats ok then its either the power to it or the switch/steering wheel...

i dare you to change that by walking out to the garage and pressing it right now.. so u can at least say its been used once....

guy 27
13th December 2009, 10:35 PM
nope. i know it works though because everytime i pop the bonnet and someone is in the car they like to press it. scares the shit out of me everytime.

Ice
13th December 2009, 10:43 PM
you want to give me your horn ? ide like to atleast try it out though if your willing.

guy 27
13th December 2009, 10:50 PM
if it wasnt needed so the car would be roadworthy then yeah i would give it to you.
happy to come round though and see if it will work on yours if you like. just needs to be before tuesday arvo though.

yea i would think the horn in all the range would be the same, im pretty sure my turbo and cdx are the same and they're pretty loud, typical of european horns

My Veccy B horn Astra Turbs horn are completely different... Veccy is quiet as, but noy faulty quiet...

ICE, throw a multimeter between ground & the horn wire, put it on DC-Volts, get someone to press the horn & see if it reads 12volts, if not the wire could be bropken smwhere or the horn in the sterring wheel is fuct or the fuse or something...

If you wanna spend $200+ to get 'Holdem Ransom' to check it, be my guest, but i would suggest you try the basics first...

How old is the car??? Or when was it purchased from the dealer??

Tried disconnecting the ECU for 5 mins?? Although i find it hard to imagine the ECU controlling the horn, but we all know how weird CANBUS is..

ok problem solved !

i took the horn off again today to have another look before I did take it to Holden and at the back there is a screw which was loose....i tightened ti and tested the horn and i heard to tiniest sound......screwed it tighter and slowly the horn came back louder :) WOO f**ken HOO, only its still is pathetic, the thing works but ill be looking for a bigger one, perhaps off a veccy or something.

Good stuff... hate to burst ur bubbole but Veccy horns or piss fart, on the B's anyhow... My Astra actually has dual horns, prolle y it's louder...

If you want decent hornage just go a set of air horns... That should fix ur problem, just use the existing wire to drive a relay (30amp) & Bob's ur uncle... You only need to run another power wire + some wires to the body for ground & to the relay & that's it...

The relay is there to absorb the switching current, otherwise you'll weld ur button together without it...
