Asked by Jan 30, 2008 at 08:32 AM about the 1999 Porsche 911 Carrera Convertible

Question type: Maintenance & Repair

Noticed horn blows when turning right, especially on hot days.  I pulled the horn fuse to stop it.  Later, the air bag light came on and has stayed on.  Since horn and driver airbag are on the steering wheel, think they are probably connected.
Any thoughts to the problem?

They might be connected, but for your horn the ring inside the steering column needs to be cleaned, this is a common issue with the newer cars, after a while dirt/dust and rust makes the ring make contact with the triggers, as for your air bag I would get that checked by a professional. Hope this helps, best of luck.


Could be that the clockspring is going bad. The clockspring in the steering column allows for constant electrical contact between the airbag and the electrical system, no matter what the wheel position. When clocksprings go bad, airbag lights come on, horns stop working or work unusually, etc. Have the airbag codes pulled by your Porsche dealer and go from there.
