Mine was also working when they wanted to!
I found out it was the button in the VIP steering wheel! If you push it really hard, and up, it would honk! I have not tore into it, to fix it yet! My center of the steering wheel that holds the button does not want to move, no screws that I can see or feel? Not wanting to damage it, I have left it alone.
I don't know if it screw's off, or you gently pry the center of the button out? If anyone has taken there's apart, how does the center section come off? It has too, somehow, come apart, to remove the wheel?
Ok, with some research I think I found it!

Wheel looks similar to this one!

So if I take that center section out, I should be able to get to the horn button! And make it work better! Rail!
