Saab 9-3 airbag light

[MrGTI6]

I recently bought a 2005 Saab 9-3 Aero convertible. It's a great car but the airbag light is on.

Also, someone has installed a switch on the dash to operate the horn as it doesn't work through the steering wheel. I feel like this could be related to the airbag light.

I was wondering if anyone has any ideas before I start buying bits I don't need!

Thanks in advance!

Thought I would update the thread. I replaced the clock spring this morning and it seems to have fixed the problem. The airbag light has gone out, the horn works, and the buttons on the steering wheel all work.

However, a couple of minutes after driving it, I was greeted with the message "STABILITY CONTROL FAILURE". Also, when I select reverse, it says "PARKING ASSIST MALFUNCTION". Could the two things be related?

I disconnected the battery before replacing the clock spring. I'm wondering if that might have something to do with the new warning messages.
