Horn itself???? I'd start looking in that order swap a matching relay first.. if not that then a multimeter is your best friend. Quote Share this post Link to post Share on other sites
pureboiracer 0 Report post Posted June 21, 2009 i had a horn relay stick on mine. the relay is in the fusebox. pull the steering wheel off. connect the 2 horn wires and see what happens. that will eliminate the switch. if switch is ok. put multimeter on the horn when someone pressing button and see if you have 12v Quote Share this post Link to post Share on other sites
