Re: horn and cruise control dont work, what to do?
You will have to replace the entire clockspring. I highly recommend having it done at a repair shop because it involves removing the air bag which contains a small explosive device and can be dangerous to someone not trained in removing it.

Was Cruise Control working before the New Horn was installed? The power supply to the Horn, (input to ground wire) is connected to the Cruise Control Module (CCM). This CCM is wired to the Relay Switch Box located in the Engine Bay. The Relay Box cover will have a Chart indicating what function each Relay coresponds to. Your local autoparts store (AutoZone) can test the Relay Switch, and you'll know (if any Relay) need to be replaced.
The CCM is also wired to the Steering Wheel, but first passes through the Clock Spring Coil, located just behind the Steering Wheel. The Clock Spring allowes for the Function Buttons on the Steering Wheel to have power while Steering Wheel spins.
The Clock Spring can malfunction or break, its rare, but this will cut power to the Function Buttons on Steering Wheel. If ALL the buttons on Steering Wheel dont work, then the Clock Spring is the Culprit. The Coil may need to be replaced.
The Cruise Control Module itself may have failed and also would cause a few or all Steering Wheel Functions to quit working.
But first check the Relay Switch Box and examine the Harness Cables connecting (Steering Wheel--to--CCM--to--Relay Switch Box--to--Battery Supply).
Also if Cruise Control was working before the new Horn was installed and now not working, then most likely the Problem is a bad wire connection somewhere and/or is a faulty Relay.
the horn could be --horn, relay or contact under the steering wheel
cruise controls need :- the brake switch , clutch switch cruise control switch, VSS sensor , engine rpms induction
all these have to be working as one or more than one will switch it off if faulty
I don't have a diagram, but if I understand what you're saying, there is a copper ring at the top of the steering column, visible before you install the steering wheel. The copper pin is connected to the horn button. The intent being that when you press the horn button, it completes the ground from the steering wheel through the horn button, through the pin, to the copper ring.
If this is correct, there should be no contact between the steering wheel and the copper ring other than the pin. Check to see if there may have been a spacer (washer, etc) below the steering wheel on the steering shaft that holds it just far enough away from the copper ring so that only the copper pin makes contact.
Hi, assuming you have cruise controls on the steering wheel, I would say your clockspring has failed. The contacts for the horn must be crossed with the cruise contacts. Replacement requires removal of the steering wheel (special tool) and airbag, etc. Please let me know if you would like instructions.
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.
If the horn nor the steering wheel mounted cruise control switches work, it is likely that the problem is the contacts that are in the steering wheel and the steering column that send the signal for these switches. You have a circular type contact that rotates with your wheel, and a stationary circular contact on you steering column that the steering wheel fits over. Good Luck. I hope you find this very helpful!
sounds like a bad clockspring. located in steering column under steering wheel, operates airbag, horn cruise etc, it make wire connection possible so the wheel can spin, its a roll of flat wires, that unroll and roll up as steering wheel is truned from left to right,wires break after a while.
It is wires wound around in a circle within a plastic housing called a clockspring. The clockspring lives behind the steering wheel and connects your horn, cruise and most importantly the airbag. Usually it is the airbag that is first to quit with a light on the dash coming on.
