Anyone ever have this happen?
Hooked up the battery after changing out my turn signal switch and the horn kept blowing, no matter what I tried.
Checked the wiring, found a short to ground in the harness going up into the column. Tore it all apart again, checking for rubbing/chafed wire. All good.
Finally found the culprit, the horn button attachment on the bottom of the switch was round and was touching the bearing housing. LMC switch, buy the way. A bit of filing and it's good to go.

Always something!
