I bet its your clockspring. Same thing happened to my 99 sport, no horn and airbag light was on. Its a pretty easy fix but the part was $70ish if I remember correctly.

SYSTEM OPERATION
The clockspring is mounted on the steering column behind the steering wheel. This assembly consists of a plastic housing which contains a flat, ribbon-like, electrically conductive tape that winds and unwinds with the steering wheel rotation.

The clockspring is used to maintain a continuous electrical circuit between the instrument panel wire harness and the driver side airbag module, the horn switch, and the vehicle speed control switches on vehicles that are so equipped.

The clockspring must be properly centered when it is installed on the steering column following any service removal, or it will be damaged. See the Clockspring Centering procedure for more information.

The clockspring cannot be repaired. If the clockspring is faulty, damaged, or if the airbag has been deployed, the clockspring must be replaced.

WARNING: THE AIRBAG SYSTEM IS A SENSITIVE, COMPLEX ELECTROMECHANICAL UNIT. BEFORE ATTEMPTING TO DIAGNOSE OR SERVICE ANY AIR-BAG SYSTEM OR RELATED STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENTS YOU MUST FIRST DISCONNECT AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE. THEN WAIT TWO MINUTES FOR THE SYSTEM CAPACITOR TO DISCHARGE BEFORE FURTHER SYSTEM SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE AIRBAG SYSTEM. FAILURE TO DO THIS COULD RESULT IN ACCIDENTAL AIR-BAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY .

Turn the steering wheel until the front wheels are in the straight-ahead position before starting the procedure. Disconnect and isolate the battery negative cable. If the airbag has not been deployed, wait two minutes for the system capacitor to discharge before further service. Remove the driver side airbag module from the steering wheel. If the vehicle is equipped with the optional vehicle speed control, unplug the speed control switch wire harness connector in the steering wheel. Remove the nut that secures the steering wheel to the steering column upper shaft. Remove the steering wheel with a steering wheel puller (Special Tool C-3428-B). Remove the steering column, opening cover from the instrument panel. If the vehicle is so equipped, move the tilt steering column to the fully raised position. Insert the key in the ignition lock cylinder and turn the ignition switch to the On position.


Insert a small screwdriver or pin punch through the access hole in the lower steering column shroud and depress the ignition lock cylinder retaining tumbler. While holding the retaining tumbler depressed, pull the ignition lock cylinder and key out of the ignition lock housing. Remove the three screws that secure the lower steering column shroud to the upper shroud. If the vehicle is equipped with a standard non-tilt steering column, loosen the two upper steering column mounting nuts. If the vehicle is equipped with the optional tilt steering column, move the tilt steering column to the fully lowered position. Remove both the upper and lower shrouds from the steering column.


Clockspring Remove/Install

Unplug the two wire harness connectors from the instrument panel side of the clockspring. To remove the clockspring, carefully lift the locating fingers of the clockspring assembly from the steering column as necessary. If the clockspring locating fingers are broken, be certain to remove the broken pieces from the upper steering column housing. The clockspring cannot be repaired. It must be replaced if faulty or damaged, or if the airbag has been deployed. When installing the clockspring, snap the clockspring onto the steering column. If the clockspring is not positioned properly in relation to the steering wheel, see Clockspring Centering before installing the steering wheel.
Plug the two clockspring wire harness connectors into the instrument panel side of the clockspring. Be certain that the wire harness connector latches are fully engaged. Reinstall the steering column shrouds and ignition lock cylinder. Tighten the shroud mounting screws to 2 N.m (18 in. lbs.) .
Reinstall the steering column opening cover to the instrument panel.
The front wheels should still be in the straight-ahead position. Install the steering wheel being certain to index the flats on the hub of the steering wheel with the formations on the inside of the clockspring. Pull the wire harness, through the lower hole in the steering wheel hut. Tighten the steering wheel nut to 61 N.m (45 ft. lbs.) . Be certain not to pinch the wiring between the steering wheel and the nut. Install the driver side airbag module onto the steering wheel.

Thanks Tim!!!

There are 2 different clock spring assys. One for the airbag/horn, and one for the airbag/horn cruise cont. ±You can use the one for the bag/horn/cruise without hooking up the cruise, but if you have C.C, you can't use the other one.

Thanks so much for this write-p, my 98 XJ is doing the same thing. . .
Do I HAVE to have the Special Tool C-3428-B for removing the wheel???

C-3428-B is a standard steering wheel puller kit and you need to buy or rent one. The steering wheel is press on the shaft and you can't pound it off.

I just had this happen to me yesterday in my '99. My steering column has felt like something has been a little loose and clunky. I was turning around to back up to a gas pump, and the column made a loud popping/ripping noise. I thought my keep got jammed into it or something. Sure enough the airbag light went on. I drove the 85 miles back to school with the thought of the airbag blowing up in my face and knocking me out at 65mph.

Is the clockspring a dealer-only part?

Thanks for the info Tim.

You can get un-deployed Airbag parts at the junkyard. All parts involved in a deployed Airbag system are one time use only and are now scrap. The airbag system is supposed to be self testing for faults so you should know right away if your used parts are functional.
