Horn stopped working 2 months ago. cruise control just stopped working. airbag light on since it stopped working

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.

Typical reason for no cruise and horn is a bad clock spring underneath the airbag. Typically you have an airbag light on as well and not an abs light

if you unplug the clock spring on the back side and the horn will stop then remove the air bag and check the switches and wires inside the steering wheel

I have a 03 van and the horn doesnt blow or cruise control doesnt work and the airbag light is on, I was looking a few months ago and found out that its a chip behind the steering wheel that controls all of that. I dont know how much it is but id call the dealership.:)

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.

yes usually your horn and Cruis control share hte same fuse and circute along with cig lighter

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.

Most likely the clock spring assembly which the wires run through for airbag, cruise switches and horn button. Requires steering wheel removal to access part.

Sounds like a bad clockspring

does your cruise control work? the reason is that there is a what is called a clockspring harness in the sterring wheel under the airbag, if your airbag light is flashing chances are this harness is broke and will need to be replaced,  The airbag, horn, and cruise control all go throught this clockspring harness.
