Title: Horn problems, please help
Post by: dhracer on April 05, 2007, 08:01:39 AM
Hi all,

I fitted a new steering wheel and quick release boss and now my horn randomly goes off whilst driving.  I\'ve tried disconnecting the horn from the boss but it still randomly goes off :2eek it\'s more than embarrasing, everyone else on the road thinks I\'m a right cock tooting randomly :o

Anyhow I think there is a horn fuse (found that in the search) which I can pull but what else do I loose if I take that out?

Where is the actual horn itself, could I disconnect that instead?

Any help would be much appreciated

if you look at your front bumper, its to the right hand side at the bottom.. bit of a pain to get to m8, check the connections, sounds like a bad earth or connection..

ah ok, no hope of doing that now (removing bumper or jacking the car up).  I need a quick fix if possible, will removing the fuse be ok for now (do you know what else I lose)?

Well I\'ve found the problem, I\'ve no idea how to fix it though :xconfused  The rotating ring behind the steering wheel boss seems to sound the horn if you push against it :spank

you have wired the horn incorrectly.  change the wiring around.

or insulate all the outside of any wires/conductive area with black tape.  that will stop any connection being made.

I don\'t think I\'ve done anything wrong.   When I press my horn button everything works correctly. I\'ve disconnected all the wires and I can still get the horn to sound by pushing against the connector that sticks out from that ring.  I\'m fairly certain (i.e. I am certain but don\'t want to sound arrogant :D ) my wiring is 100% ok.

I\'ve used properly insulated soldered joints, insulated connectors and heat shrink where applicable.  It seems this ring is of a poor design and because the new steering wheel boss presses against it slightly this causes the horn to go off :Hammer

It looks like the ring will come apart so I\'ll try and see if I can come up with a better solution than the OEM item when I get home.  For now I\'ve pulled the hazard fuse in the drivers footwell, I can live without my hazard lights for a bit I hope :)

My guess is that you\'ve worn the plastic down so it doesn\'t really press against it much anymore - in the 2 short trips I\'ve done with the new steering wheel I can already see that the plastic is wearing in places (it also shows me the main place where the rubbing is occuring - full lock turning right)

I think that\'s what I\'m going to do, you don\'t happen to remember which wire you had to cut do you?  (or am I going to have to look throught the manual :3Confused )
