Question about 1999 BMW 318 ti

2 Answers

Car Horn I have a 1998 318 Touring and every time of late I press the horn, the fuse blows! I've tried 3 fuses so far and all are fine until the horn is pressed and then the fuse blows straight away without the horn even sounding! I heard it could be a short behind the steering wheel, but that's where the airbag is and will be a pain if that's the case!! Any ideas? Advice?

Hi djdecks,

I would think that the problem is more likely to be on the hot side of the horn operation, than on the earthing.....Power is fed to the horn and is grounded, completing the circuit, when you press the button....Check first on the horn relay and follow it from there.....I don't believe the problem will be behind the steering wheel, unless the horn sounds all the time....

Best regards Johngee10

Horn randomly honks(very annoying while your trying to sleep) HELP!


its possible that the relay is the problem as most relays have a second power feed wire,if it shorts to the horn side of the relay it can blow the horn.doesn`t happen very often but it does happen.this could explain the horn blowing without the fuse in.you can get a door key made at a lock smith to solve that problem.

2004 Malibu Maxx keeps blowing horn fuse. Works when I replace fuse for about 6 times. Horn itself feels touchy as in only works when pressed certain way. Shift paddle on side of shifter also does not...


Try disconnecting the horn itself from the circiut,hold the horn button on for a while,if the fuse no longer blows,it's a safe bet the horn itself was the culprit,if it still burns the fuse,the wiring or clockspring are shorting out

When running air condition, if i blow the horn both stop working, until i replace the horn fuse


try unplugging the horns to see if they are the problem. If the fuse still blows, the problem is the wires from the relay to the horns. If the fuse doesn't blow, plug in one horn at a time to see which one is bad.

Horn blows constantly, doesn,t blow the fuse or anything else. can this problem be outside of the horn blowing assy. on the steering wheel? it,s a 2000 galant. problem occurs all the time if the switch is...


  • The horn relay might have welded contacts (stuck in the on position). Pulling the relay should stop the horn.
  • The wiring harness on the steering column might have a broken wire to the horn relay shorting to someplace that applies power to the relay. In this case, turning the steering wheel all the way to one side or the other may stop the horn, and it won't sound when you press the horn button.
  • The horn button in the steering wheel is stuck on or shorted.

My horn on my Buick Skylark will not work. It blows every horn fuse we replace. How can I get it to work?


You may have a short circuit in your horn button causing the
fuse to blow when you press the button or in the horn itself.

1. Locate the horn under the hood normally in the front of
the engine compartment.
2. Once you locate the horn, disconnect the wire from the
horn.
3. connect a VOM (Volt Ohm meter) to the horn's wire.
plus(+) side to the wire and negative (-) side to ground
or some metal part on the car.
4, set the VOM to dc voltage and have someone press the
horn button. You should read 12 volts on the VOM, if
not you have a short in the horn button, if you do mread 12 volts
you have a short in the horn. Replace the horn....

04 CooperS: Horn does not work


Check the fuse first. should be in the drivers footwell. Make sure that it is not blown. 90% of the time fuse will just blow due to high resistance from one of the horns. There is a high and low horn often it requires to replace one and try the horn and see if it blows. Then replace the horn that blows the fuse.

Horn blows fuses


you may need to put a relay in it as the current from the horn may be back feeding up the immobiliser horn circuit and causing a short. Sounds like the immobiiliser has its own source of power seperate from the factory circuit When you press the horn the power goes to the horn and up the immobiliser horn circuit and it blows the fuse.
