My air bag dash light was showing and i lost my horn i checked the fuses and relays there were all good. Then i checked the horn by using a wiring an earth to the horn connection and the horn worked. i removed the all the fuses and wiring from the steering column for both the horn and air bag. I removed the airbag then the steering wheel and the clock spring and replaced the clock spring and and put it back together. I put the fuses back and tested the horn it works then started the car and the airbag wasn't showing on the dash and took the car for a drive and all good now.
