Horn not shutting off

[Pinkdubai]

The truck has an aftermarket shaft put on by the previous owner. I’m not able to find any details regarding the manufacturer. As noted by Richard, I also have a one piece hub and cap from Forever Sharp, which fits the splines better but still results in the turn signal cam being compressed too far. It seems like I’m missing a piece that prevents the turn signal cam from sitting directly on top of the turn signal mechanism.

Appreciate all the comments so far.

Sweet!
I have the same issue.
Replaced the stock steering column with a CPP unit and a Forever Sharp steering wheel and adapter kit.
Now, I had the steering wheel on it before, and the horns decided to magically start blowing when I wasn't at home.
The wife called me and sadly before she could pull the relay plug, the gorns quit on their own. (Burnt out)

So I replaced the column with a CPP tilt and the Forever Sharp wheel...along with a new set of horns.
Same thing...the horns are on ALL THE TIME.
I have pulled the wheel off and looked at the horn button, but it is still grounding out somewhere, causing the horns to stay on.

I removed the spring that was in the top section, because I thought it was WAY too much pressure on the plastic signal canceller...no change.

It's gotta be grounded somewhere because the horn button does nothing right now. The circuit is grounded before it even gets to the horn button.
