Q: Horn honks randomly

asked by on February 13, 2016

The car horn randomly blows. We think the wire is grounding out. The horn is currently disconnected and still honks randomly.

Hi. The horn switch on the steering wheel energizes a relay on the vehicle which then powers the high amperage horn. A shorted wire or malfunctioning relay in the system are possible causes for the intermittent activation. Have an experienced technician inspect the electrical system and circuitry for faults.
