S60 D5 horn always on!
The horn went off and was permanently sounding. It sounded long enough that one of the horns burnt out and then I think a fuse blew, which stopped the sounding. Whilst it was sounding countiniusly I hit the steering wheel (out of embarrassment and frustration) and it stopped but then went off. And so on. And then the hitting stopped working!
The mechanic refitted a fuse and disconnected the horns. But when he reconnected the working horn, it’s starts sounding. Mechanic doesn’t know how to fix it. Is there a fix for this? |

they are under the part of the steering wheel which you press . Not that easy to get off unless you have the knack , spring clips have to be released and you have to get the air bag out with it , If you don't know it is best not to attempt it or it could be costly .

I think a connector inside the steering is not working. Changing the steering wheel is the cheapest option for me. Are all s60 steering wheels the same?

Could the clock spring cause the horn problem?

Ok thanks.
Is there a step by step guide on changing the steering wheel? Is it easy? I will off course disconnect the battery as I don’t want the air bag going off in my face!! |

Before poking around in a steering wheel, especially if one is inexperienced in removing airbags (another job not too dissimilar to the coil spring removal. Dead easy to do, but frightening as you like whilst you do it), I would want to see some confirmation that it's the steering wheel switch.
I accept it's likely, especially after clouting it one and the state changed, but the horn button signal goes through the watch spring and into the loom by the column. From there, it goes to the CEM by the driver's right knee (assuming RHD). From there the supply to the horns is switched on. Banging on the column could have knocked the failing relay or short or whatever's wrong, say in the CEM? I cannot recall if they are earth switched (i.e. they are permanently fed and the earth return, via the switch or a relay dependant on the switch, completes the circuit.) If that were the case, then if a rubbed wire found itself against something metal, that could give you the problem you have. You could be poking around the steering wheel trying to find a problem that's actually at the other end of the car. If it were me, I suppose I probably would start poking around the horn switch because I've done it plenty enough times already, but the proper method really should be determining where the short is before taking too much apart. I guess I'm suggesting don't be too certain you know exactly where the problem is, you can only have a guess. |
