Rogue horn in '06?

Yesterday the horn in my '06 WK (5.7 Limited) started sounding intermittently. Without any pressing of the wheel center. It first happened when I was turning the wheel. It happened again if I used the turn signal stalk, either to pull the high beams or indicate a turn. It is not repeatable, as in, it won't always sound the horn based on an action.

The only things that have changed recently was to have the interior detailed and four new tires. No other repairs or anything 'moved around'. The detailing was a week ago. The tires, two days ago.

It has 86k miles on it (not that much for 10 years). I have replaced the battery; probably back around 65k if I had to guess. It has had no electrical gremlins in the past.

There is one thing, the left steering wheel buttons for the radio have been intermittent for a while. If I press the up button sometimes it gets confused and think I'm adjusting the volume (controlled by the right buttons). I've attributed that to potentially dirty connections underneath the buttons. This has been happening for several months, and there have been no horn troubles at all up until yesterday.

We have not had any rain recently. I checked anyway and there's no moisture in the floorboard areas (front nor back).

My first plan will probably be to pull the horn fuse. I can't drive it around with the horn sounding at random.

Where do I start debugging this?

I'm not superstitious but maybe it knows it's time is growing short. It's replacement won't be here until October. Damned thing better not start acting up...

Re: Rogue horn in '06?

This sounds like the clock spring in the steering column is starting to short out. This is the part that makes connections through a turning steering wheel. The horn and the radio buttons both run through this connector and it is known to fail. If your cruise control acts up or you get an air bag error, it is probably that connector.

I agree check the clock spring first. If it's not that I would look at the multi-switch as those wires pass through there also.
My multi switch just went bad for the second time in my Dakota. Symptoms both times were headlights would intermittently just go at night, tail lights worked but brake lights didn't - new bulbs no help, left turn signals would flash really fast like a bulb was out but all lamps worked, and intermittent operation of cruise control. That one switch assembly can make all kind of electrical gremlins pop up.

The service manual offers some rather comprehensive and convoluted steps with regard to the SCCM and the clock spring. Just how 'necessary' is replacing the SCCM? It is possible to replace just the clock spring assembly? I've got all the tools to do the complete job. I'd prefer to avoid shelling out for the SCCM if it's not already bad.

What do you mean by 'multi-switch'? There's the control module (55117000AG). Is that what you're talking about? What did that repair cost you? As that would put a frame of reference on what parts might have been involved.

The module is around $350, apparently. The spring itself is apparently a lot less, but replacing it is a little more involved than doing the whole module (which includes the spring already set up).

The multi-switch controls the turn signals, wipers, headlamp dimmer. It consists of the stalk that you manipulate and the switch it is connected to inside the steering column. My first OEM was over $120.00, this second one I purchased an aftermarket one made by Standard Products for around $50.00 on Amazon. It had some great reviews. Must pull air bag and steering wheel to replace it.

Re: Rogue horn in '06?

Ah, I get what you mean. I'm not having any turn signal or light control problems (yet). Just the radio buttons on the steering wheel and random horn sounding. Both run through the clockspring, apparently, and then into the same module as the switches.

My bad. It's actually called a multi-function switch. The sun got in my eyes.

Re: Rogue horn in '06?

Ok, replaced the clockspring scm assembly and the horn stopped being a problem. The radio buttons on the wheel now also work correctly.

Still see an airbag and ESP light. Still no DTC codes. What's next?
