How to troubleshoot a non-functioning horn in the Great Wall C30?
1 Answers
Turn on the headlight switch; if the headlights do not light up or appear dim, start the engine. If the headlights then function normally and the horn sounds, it indicates insufficient battery charge. Press the horn button and check if the relay makes a "clicking" sound. If the horn has poor grounding, remove and reinstall it. If the horn is damaged, replace it with a new one.
