: Horn stopped working.

04-06-13, 12:48 PM
Horn stopped working last week when it got really cold again after it had warmed up. Same as with my father-inlaw car. They both stopped working around same time. And both cars make a sound when horn is pressed. The only thing I can relate the sound to is its almost identical to the sound the high beams make when put on. Has anybody had issues or know what has happened. I'm thinking its just electrical but have no idea what to.


Any help or comments much appreciated thanks

easy. horn locate under front driver side bumper. unplug it and test horn with muliteter set on oms. any resistance? test wiring volt output while some one pressing horn inside of the vehicle. but before u do all that check all your fuses. there is also relay that could fail
