Steering Wheel Re-Installed - Horn Goes Off Continuously

I had to pull my airbagged wheel off to do a dashboard replacement. Upon reinstallation the horn started going off when I turned the wheel and now it goes off as soon as I turn the ignition on. Any ideas?

My guess is that you got an exciter wire grounded when you put the wheel back on.

What year/model do you have? There should be a wire or contact the is behing your airbag for the horn. Chances are you got it too close on re-installation.

Two wheels or Four, I'm happy as long as the throttle is pinned.

I have a '90 325iC.

I'll check on that wire. There was one small plug that attaches to the back of the airbag. There was also a wire in the wheel that was not reattached - my airbag is not 'hot' so I did not see the need to reconnect this wire. Probably my culprit?
