What to Do When the Citroen C-Quatre's Locking Horn Doesn't Sound?
2 Answers
The solutions for the Citroen C-Quatre's locking horn not sounding are: 1. Replace the horn; 2. Adjust the wiring; 3. Poor contact in the switch—you can turn on the headlights and press the horn, open the handlebar at the horn button, use a hairdryer to dry it and check if the soldered wire ends have come loose, then open the protective cover at the horn to see if the horn connector is loose or detached. Taking the Citroen C-Quatre 2016 Classic Sedan 1.6L Manual Comfort model as an example: it is a compact 4-door 5-seater sedan under Dongfeng Citroen, with dimensions of 4588mm in length, 1773mm in width, and 1486mm in height, a wheelbase of 2610mm, and equipped with a 5-speed manual transmission.
When my Citroen C-Quatre's horn stopped working, I first checked the fuse box myself. I located the fuse labeled for the horn to see if it was blown, and replacing it fixed the issue. If that doesn't work, it could be loose wiring or dirty contacts – a quick clean with a small brush usually does the trick. This is a simple job that saves money and time. If you can't fix it yourself, don't force it; seek professional help to avoid disabling the anti-theft system. A silent horn during locking means others might not notice, significantly reducing parking safety, so get it repaired promptly. Regular maintenance checks on these components can prevent major issues.
