Hi. My 99 Blazer horn won't work. It works when I press the button on the keyless remote, but not when pressing the air bag horn button. Any common problems I should look for?

 

I have seen the contact where the wire goes into the column behind the airbag to get dirty and cause the horn to stop working. Just pull the airbag, and take the red wire that goes into the column, it is just to the upper left of the steering wheel nut, and disconnect it and clean that. Korey.
