HORN!!!!!! It's on and won't stop!!!!!

[Patruck]

All the threads I have read are related to horn not working!
well mine works and boy does it, problem is it won't stop working unless I unplug the wires to solenoid!
I was just cruising down the road and all of a sudden HONK!!!!
had to pull over scramble onto the hood chicken scratch to get it open pull plug out of horn and now I can't hear nuttin.
button on wheel still seems normal changed horns completely with another I have from second truck! Still just blow as loud as it can until it drains the air tank or I pull plug!

what in the world have I done and how do I make it stop?

You probably have a grounded spot in the wire that runs down the steering column from the horn button. A lot of them get really roughed up where they leave that center shaft and turn towards the horn. Glen

Unplug the electrical connector from the horn. If it keeps blowing, the valve in the horn itself is probably stuck. Don't know if it is repairable.

If it stops blowing, then its an electrical problem and 91W350's suggestion is the likely cause.

OOPS... I guess you already did unplug it as stated in your OP.

Just shoot it!

Glen is correct, look right where the wire comes out of the steering box, if the problem isn't there, it's probably inside the steering tube. Look at the TM drawing and replace/repair the wire.

If its parked by a good looking A3, this could be the cause of its horny-ness.

Oh yeah, almost forgot... Ditto on checking the wire coming through the steering box.

Ditto on the ground wire shorting. While you're at it, pull the air line off the horn and give the solenoid a few drops of oil to keep it well lubed.

Even if it's the wire give it some oil. I like the PB Blaster air tool oil.
