Horn not working...Any guideline for trubleshooting?

[Akhil]

Hi Bimmer Gurus,

I am here again with another question. Its been a while since my horn has n't working, but I just kept on ignoring that problem until now, since I never used it even when it was working. But today, it happand so, one A$$ was watching me coming from distance and talking on phone, but as soon as I came very close, he just pulled right in fromt of me, I had to brake really very hard to save his A$$. So I decided now I can't live without horn any more, with all these people talking on cell phone while drive and dreaming about other world. I need my horn to bring them back to this world. :p

Any way, Do you guys have any idea where should I start my trubleshooting? I had my steering /air bag thingy out without disconnecting the connectors, but could not find out how horn works and where its connectors are. Any insight will be helpful for me.

Thanks a lot in advance
Akhil

seems something in steering wheel. When I took air bag out and puting it back some time horn blew by itself but after finishing that job did not work. Something seems like lose contact or sorta thing. If there any really some where I should be checking too?

Thanks

i dont know what wheel you have but mine horn stopped working and the fuse was ok.I just fiddled around anf the horn push came off.I poked around and put it alll back togeter how it seemed it should.And now it works

[632 Regal]

if you have an airbag you should disconnect the battery before messing with the wheel.

from what you mention I think your right about something in the wheel because the horn blew upon assembly.

I heard something about SLIP RING. Is that slip ring for connecting horn connection or for air bag connection? And If my slip ring is bad then what is the procedure to replace without cousing SRS light truned on? Since I heard that resetiting SRS light is expensive, so I dont want to couse that.

There might be a relay for the horn too, I don't recall at the moment.

Also the wires have a habit of breaking in some parts of the car so check the connections at the horn.

Also, apply voltage directly to both horns to verify that they still work, although most likely only one would go bad a time.

putting steeting wheel/air bag componet togater, after finishing that job its worked few times until I didn't turn steering wheel. but after trurning wheel once it didn't not. Do you anu idea, how wire/connection works on rotating wheel without twisting its wire? I am guessing the mechanise to rotating connection have some problem.

It sounds like you may have misaligned the connection while putting the wheel back on.
Otherwise it could be a bad slip ring(32331152896). Im not sure thats the correct part number, since its been a few years since I took off my steering wheel.

The best bet is to take it off again and check for a broken wires in the connector. I don't recall if it has a limited number of turns before breaking the connection, but that seems possible you had it turned too far one way when it was put back together.

slip ring is for the horn connection? I was thinking it is only for air bag, correct me if I am wrong. If I will have to replace slip ring, how hard is that job and how to do this job without cousing SRS light to come on?

Any instruction/ precaution ? Since you have exerince doing it even if long time ago, you will no better than who never did it. :)

Sorry, but I don't remember exactly how everything was in there, so im not sure if the the horn just uses a sliding contact or if it uses wires through the slip ring. When I took it apart, I didn't replace the slip ring.

Try tracing the horn wires from the steering wheel button connection back and at some point you should find something abnormal. It may be obvious when you take it apart.
(Remove NEG batt. cable 10 minutes before that...)
