Alright guys, I was driving home from my bach the other evening when all of a sudden my horn started to BLEAR! it was just as i made a kind of tight turn around a corner if this makes a difference. The horn kept going so I pulled over to the side of the road, I was travelling on a gravel road and i thought the horn might have gone off to let me know that maaaybe i had a puncture ( i know absolutely nothing about cars ) anyway, looked at all my wheels was all good so i popped the bonnet with the horn still going make a constant sound, no delays at all. I wondered around the car like a blind man not knowing what to do, i turned the car on and off twice thinking that might reset the computer but that didnt work. And then all of a sudden, it stopped... YES! i can carry on my journey but to figure out i now have no horn.. I have a manual with me which came with the car but it doesnt help that it is a calais manual.. I dont know why this manual came with the car. Anyway, I'm trying to look for a fuse box or something either under the bonnet or near the steering column, I have checked all the 10-30amp fuses under the bonnet but i cannot find the fuse box under the steering column, (if even there is one). I dont really want to take it to a holden dealer because I dont feel this is a rocket scientist problem so I am reaching out to the Holden community to help me out Cheers guys.
If the horn relay isnt in the engine bay fuses relay box inside fuses and relay locations there is a wide plastic flap you pull down just around and below the steering column it has fuses and relays fault codes https://www.youtube.com/watch?v=tl492uEGtBE
As you said, it came on when you turned the steering wheel. That being the case, I'd say it's the clock spring behind the steering wheel. If it is, the steering wheel has to come off. Horn relay is in the engine bay fuse/relay box, located drivers side. It has a long, black plastic cover over it. For the fuse/relay compartment inside, pull down the the panel, (from the top) directly under the steering wheel. There you will find the horn fuse.
Ok thanks guys, so I am looking for a horn RELAY rather than a FUSE? I came across this wide plastic flap under the steering column but when I tried to pull it, there wasnt much give leaving me thinking this was not what I should be pulling off. Am I wanting to be pulling this plastic flap up or down? @Nut Kracker - Is it much of a mission to get to this clock spring? When you say the steering wheel has come off, what do you mean? My handling is fine and no difference to before.
in about two weeks in this forum you will know all there is to know about your car ... you need to check the horn fuse now if its not working-- then relay - then the steering column last its takes a tug to get the wide plastic flap under the steering column - to release from the clips and it is hinged at the bottom flap goes down horn /air bag to clock spring the battery has to be disconnected before removing the airbag -horn section it needs a special bit ( its not a phillips or straight edge screw driver ) to undo the 4 x T30H Torx screws of the air bag and horn section from behind one forum .write up http://forums.justcommodores.com.au...7-2002/162723-how-change-clock-spring-vt.html
I can't see that if the horn is working, that is, going off when you turn the wheel, that it would be the fuse or the relay. Because of the constant turning of the wheel, the clock spring can wear and the wires can short together, causing a faulty connection. The clock spring is usually a piece of multi strand, flexible, ribbon with wires in it. It can resemble a coiled spring found in clocks. Hence the name clock spring. This flexible "spring", allows the steering wheel to turn, while maintaining a connection from the switches on the steering wheel, to the horn, airbag etc.
see 21 that's what it controls on your car , replace if blown . see the relay , if your fuse blows again remove it ... till you can fix the clock spring so you don't blow another fuse . or so try a different relay to see if its not the problem . good luck.
It is, if only a little annoying with the horn going off. If it gets really bad, pull the horn fuse or take out the relay. If it is the clock spring and you keep on driving it for a while, it may also eventually wear enough to effect the SRS air bag. If it does, the SRS warning light will show on the dash, they will not activate in a crash and the fault code will have to be cleared after the clock spring is replaced.
Number 21 Fuse is for the instruments and theft horn. The OP needs Number 25 Fuse - Horn....3rd from the bottom, right side.
I've had the same problem and as you know it's a very embarrassing experience. Check the horn fuse, see if its blown. If its blown I'd start by replacing the actual horn under the front bar since it's the easiest and most inexpensive part to replace. My issue was a faulty horn, all I did was replace it with a second hand one and now it works fine. Replace the fuse and test if it shorts again
