Horn and cruise control stopped working

There could be a fuse or relay issue since multiple systems became inoperative simultaneously. I'd suspect that when the alarm went off, someone targeted and disabled the horn system so that it wasn't honking inside the repair facility. Both the horn switch and cruise control switch are located in the steering wheel and therefore they share common components and circuitry. Try checking under-hood fuses #7 (7.5A), #13 (20A), #15 (40A) and #20 (40A), as well as under-dash fuses #7 (7.5A) and 21 (7.5A). If all these fuses are OK, much deeper diagnosis will need to be performed. One somewhat common failure item is the spiral cable (also called a clock spring) that transfers power to the steering wheel (while allowing it to turn). That part can be seen within the steering angle replacement procedure shown here: https://www.yourmechanic.com/article/how-to-replace-a-steering-angle-sensor-by-marvin-sunderland

If the switch is replaced,then it can be wiring issue or faulty cruise control board.But as the switch is replaced,get the voltage at the switch tested to confirm the switch is actually receiving voltage.If no voltage received at switch power supply wire then ,apply external 12 volt power to the cruise control switch wire and then see if cruise control comes ON.If yes,then you know wiring is issue.

Is the AIR bag light on too? Sounds like it might be a bad clockspring.

The horn relay is located toward the front of the engine. It is located just behind the radiator overflow reservoir and attached to the inner fender next to two other relays. It is the only one without a plastic cover over the top of it. FYI, our Crown Vic horn didn't blow, and the cruise didn't work. I changed the relay and still no horn. I decided to check the horns themselves. Found wires disconnected from terminals. Touched wire to horn terminal and horn blew incessantly. (previous owner had disconnected horn rather than diagnose why) Pulled the horn "button" from steering wheel and disconnected the wire leads and horn quit. Disassembled the "button" assembly. Foam had degraded over time between the contacts. (Ford has discontinued this part). Cleaned and replaced foam with Scotch foam mounting squares with holes punched out over contacts (2 layers thick). Re-assembled and viola! Horn and cruise control both work! Relay was bad as was horn button.

I have the exact same problem. Occurred after car was jump started. Havent been able to find any solutions. Did you solve this problem?
