Horn goes off on 2008 C300 4matic while off
This evening my sons car horn just went off. Hit lock/unlock on fob multiple times no luck. Started car drove it and the horn stops. Shut it off and the horn blasts! Battery is at 97% and was replaced less than three months ago. Could not get it to stop and neighbors called the police. Had to disconnect the battery and it stopped. Any suggestions other than take to a mechanic? Thank you in advance.
