What does 'cruise control' have to do with the horn not working?

..

Maybe. The fuse is a 15 amp fuse, #18 in the Power Distribution Center. Be advised there is also a Body Control Module in the wiring. A gray with orange stripe wire from the horn relay's coil side to the BCM and then to the clock spring and then to ground through the horn switch. This gray/orange wire should be hot at all times, both into and out of the BCM.

Pull the air bag module , don't recommend you do that ! Is the air bag light lit on the instrument cluster ? Horn not working an air bag light lit would indicate clock spring problem . Do you know what the clock spring is ?
How cars clock spring works

Did you check the horn relay ? Do you know what a relay is ?

VEHICLE RELAYS Operation Diagnosis

no hor no cruise could be the clock spring the high beam indicator if you have high beams then the light behind the console on top of the I/P must be blown.

you need to have the codes read for the air bag to know for sure which direction to start ,but yes, they are all tied in to the clock spring.

Dodge has a recall on the clock spring. The clock spring is more than likely what is causing your problem. It is located in the steering column, and allows continuity to the horn, cruise, and air bag. The contacts in these loose contact and cause this problem. It will sometimes cause the air bag light to come on also, but not all the time. If your fuses are good then it will prob be this.

Air bag light on ? Have the vehicle checked for DTC'S - diagnostic trouble code's in the air bag control module . That's the way to find out what the problem is . Suggest you take it to a qualified repair shop.

You can check the clock spring. Remove the cover over the stealing wheel where the emergency flasher is. At the bottom there are two connector side by side. the small one on the left is for the Air Bag, the one on the right (6-7 pin connector) is for the horn and cruise control if you have one. Disconnect the right connector. Us a wire to gound out the pin in the lelft side of the 6-7 pin connector. If the horn sounds, then it is either the clock spring or the air bad itself that needs to be replaced. I would bet it is the clock spring.

Replace your steering column clock spring which carries the signal from the air bag, horn switch, and criuse controls.

there was a recall for an air bag problem which also fixes the cruise control and horn (clockspindle in steering wheel)
