Now? Horn will not stop blowing?

Did you blow the fuse? Look under the fuse box lid...there is a horn relay

I always pull the fuse when I have to pull a steering wheel.... too many ways for a lead to get away from you. Hook up on the button normally doesn't matter. Check the fuse?

Start from beginning .... Slingshot is off?

Did you damage the clock spring not sure if it would cause the horn to stop working

Does the original wheel/horn work if you just test it back?

If so maybe defective component?

run a jumper between the two wires behind the horn button to see if the horn works. If it does the button is faulty. if it doesn't, the clockspring may have been damaged. I wrecked mine just pulling the stock wheel off.

What was today's Sling project-Mods , goodies.....?

I had the same problem and it was the clock spring, hard to see if damaged. See link above.

Maybe it's just indifferent - it doesn't give a hoot

I've had intermittent problems with the horn as well. Last time at the dealer, they ended up having to replace something. Not sure what as they didn't tell me, but It's back to working once in a while if at all . Clock spring is easy to test by just jumpering the 2 wires inside the the horn together. On occasion, reseating the horn relay has worked... but again, only temporarily. As of now, it's dead again and hasn't worked for a few weeks now. Just piling up "issues" so I can make the dreaded trip back to the dealership.

This morning, I turned the key, and the horn is blasting away? Turn the key off, horn stops.

the horn only works with the key on, I believe all are like that, it's normal

Sir,
horn is blowing on its own when I turn the key to start the Slingshot?
Horn is blowing without out me pressing on the horn button?
Also, strange. All the wires are disconnected and the horn is still blowing when I turn the key on??????

oh, gottcha, that's pretty messed up, I know when I put my wheel on, I had the same or similar problem. I tightened the wheel, turn the key,..horn would go off. I had to reset the wheel about 5 times before I had it lined up perfect. Sorry about your issue, good luck

Check the wires to see if they are grounding out.
Put the relay back in
With the steering wheel removed
Turn on the ignition
Move the wires around
If the horn stops you have s ground short on one of the wires
Common problem.
Mine used to do it when I turned left.

Mine did that before I changed the clock spring the connector on the clock spring caused the problem. This clock springs suck.

Sounds like the horn wire is shorted to the key hot wire
