So after finishing my 100k service and washing car found leaking washer fluid hose by hinge, closed car to try enjoy rest of the holiday. For no apparent reason horn started going off and then shut off on it's own after 5 minutes. 20 minutes later it repeated for 10 minutes, disconnected battery then checked relay. The under dash cover was wet as well as the relay panel, blew everything with air hose reconnected battery and 30 minutes later it repeated pulled relay to spare my hearing and the neighborhood. Any suggestions where I should start troubleshooting?
