    horn stopped working - 428i

    The horn on my 2014 BMW 428i stopped working. I wanted to check the fuse but the fuse chart just says to take the car in for service for the horn. Would appreciate any thoughts on how to fix the problem without taking the car to a service center. Thanks.

    Fuse 14 on front electronics module powers the horn.

    But ideally you would need to scan the car for codes with a BMW scanner. There may be many reasons for why it's not activating.. example, there may be a wire shorting and the car is simply protecting its electronics.

    Horns aren't an unusual failure. If there's power to the horn, just replace it (them).
