horn issue

Redfish,
I can only say that the screw was what was on the lever when I took it apart, the nut I replaced due to the one that was with it would not hold the screw anymore. I replaced that after the horn issue. I will not rule it out - I have the orginal column at the house I will take it apart and compare / take the screw and nut from that unit.
I also noticed last night I took the under column support out last night and it look like the black wire has sone chaffing on the shielding I am going to tape that up also and see what happens then not sure if that will cause the issue or not. I would think that if that was the issue the horn should be blowing reguardless of the wheel?
But I an not sure of anything with this one.
