I have a Lincon LS 02 my horn just stopped working
Horn broke, watch for finger! Just kidding. Check fuse yet?
Maybe wiring at the horn itself got cut by debris. Voltmeter at terminals and check for continuity and voltage when horn depressed. Pretty much all I can think of right now.
Thought of something else. Relay for the horn.
Check harness connection at horn
