Make sure when you change the switch that you also change the the horn contact pins along with the new switch. You might want to take them off of the old switch. I did my switch without knowing about the contact pins and now I don't have a horn. The only place I can find the pins are at the stealership, of course the pins have to be ordered, so I'm still without a horn until they come in. A more experienced/advanced tech on this board can tell you how and where they go.
