horn intermittent

[mrrandom]

I have a 03 montana that the horn works when it wants to. We have installed a new button on the side of steering wheel. We have replaced the relay and the horn itself. When I press to honk the horn I hear the relay click but nothing to the horn. Any ideas?

Did you put a voltmeter on the output of the relay to see if you have a reading? Did you check the horn grounding?

I believe you actually have 2 horns one is located near the battery under neath it near the fender and the other is near the other fender,usually the horn itself goes bad . A good way to trouble shoot this is to out the drivers side headlight assembly and then the horn is exposed un plug it and check for voltage when the button is pressed. It does sound like a weird problem cause both would be bad?? I guess its possible keep us posted .
