...on, what could be causing this? When i press the horn it doesnt sound, the interior dome lamp comes on and there is a buzz behind the dash board. The fuses are good. What could be the problem? Thanks

man you have a short in the electical system. check and see if the horns work by putting 12volts to the horns if they sound they are good. check the wires to. good luck

replace the horn itself sound like it's shorted out or first just disconnect the horn and see if it does it then if it doesn't it is the horn if it does it it is a short
