Horn Issue

[dodger73]

Have an 86 M1008 that every now and then when I turn the steering wheel to turn a corner the horn goes off. Sometimes it stays on & you have to hit the steering column right where the steering wheel and column connect in order to shut it off. It will go months on end with no issue and then all of a sudden it's a problem again. Have taken the horn assembly apart and I don't see anything wrong. Anyone have any ideas on what's going on here? Greatly appreciate any help, thanks.

I have had that happen before. If I remember right the convex round piece was in upside side down.

I had a few issues with my horn. Purchased a rebuild kit (spring, rod and something else) from NAPA. Cheap and it was an easy fix.

Thank you, I will look into both suggestions.

There is also a internal horn button and spring inside the turn signal assembly, inside steering column.
I chased a horn issue for months before finally finding an issue with that button and spring.
Installed NOS GM turn signal assembly and problem solved.

Continues to be issue free.

So if the above recommendations don’t solve it, I would look into replacing it.
