Is there anything I can do with the horn and cruise cntrol not setting from steering wheel buttons?

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.

replace the spiral spring wires under the steering wheel

Sounds like to me someone might have taken the steering wheel apart at sometime...and might not have reconnected the horn and the cruise control properly...i have seen that before...does not hurt to check that

More than likely a short in the headlight/ turn signal assembly that is going to ground in the steering colum.

the steering wheel is held on by one large bolt remove it then you will need a steering wheel puller.

In most cases this problem is caused by the rotating ribbon circuit contact under the steering wheel having a broken filament, the part is known as a clock spring contact, u will need to properly disarm the airbag and remove the steering wheel to access the part. WARNING: Failure to follow factory Airbag disarming protocol can result in an unexpected Airbag deployment and possible serious personnel injury or death.

sounds like there is something in the wrong place in the horn button. it makes contact when you turn left just as if you had pushed the horn button. i wonder does your airbag light ever come on, i mean not just in the startup sequence, that's normal. probably you need to take the horn button part of the steering wheel apart and get things back in the right place or maybe replace some parts, but because of the airbag being right there too it's not something i would recommend that you do yourself. accidentally setting off an airbag is not a good thing.

sounds like the horn contact terminal inside the steering wheel got disconnected and is hitting a metal part of the steering column which triggers the horn. the terminal that got disconnected is probably has positive polarity and the metal part of the steering column has negative polarity. If they come in contact with each other... *honk* *honk*

As long as the light is on the airbag system is disabled.

I would suspect that your clockspring behind the steering wheel is going bad. I would have someone with a scan tool that is able to retrieve trouble codes from the airbag system check it for codes to verify this. If so then steering wheel and steering column trim would have to be removed to access the clockspring to replace it.

Todd, If your Air Bag Light is on and your cruise control does not work. Contact me before doing the test procedure below!

Todd, sense you have the steering wheel cover off, we need to check to see if it will honk when you take the ground wire for the horn and ground it anywhere to a good ground, preferably the ground post from the battery. We know this is always a perfect ground! The wire for the horn will be a single wire all by itself. If it doesn't Honk see below.

Next: Next we want to ground the horn wire coming out of the other side of the steering wheel, this is much harder but will tell us what we need to know.

Let me know what you find!
