What are the reasons for the Roewe 550 horn not working and how to deal with it?
2 Answers
Roewe 550 horn not working is mainly caused by a blown horn fuse. If both horns do not work, it may be a problem with the horn relay. The following are the methods to deal with the horn not working: 1. First, check whether the fuse is blown, then unplug the horn connector and use a multimeter to measure whether there is electricity when pressing the horn switch. When people press the horn, two contacts need to touch to make the horn sound. If people usually press the horn frequently and forcefully, it may cause the contacts to burn out. Once the contacts are burned out, pressing the horn naturally will not work. 2. Check the power system. Turn on the headlight switch. If the headlights do not light up or are dim, start the engine and slightly increase the throttle. If the headlights are normal and the horn sounds, it means the battery is insufficiently charged, and the battery can be charged. If the headlights are normal and the horn button is pressed, check whether the relay makes a clicking sound. If it does, it may be a problem with the horn damage or poor horn connection. The horn assembly should be replaced or the poor connection fault should be eliminated.
The day my Roewe 550's horn stopped working, I quickly turned off the engine and got out to check. First, I located the fuse box near the steering wheel, pulled out the small piece labeled 'horn,' and sure enough, it was blown and blackened. I replaced it with a spare fuse of the same amperage, pressed it back in, and the horn worked immediately. If you don't have a spare, buy a few online as backups; horn failures are often due to rainwater seeping in and corroding the coil or oxidized and loose electrical contacts. Tighten the wiring connections to prevent short circuits from aging wires. Before handling, disconnect the negative battery terminal to avoid electric shock. Solving such minor issues yourself saves time and money while teaching you some car repair skills. Regularly clean electrical components to prevent dust buildup from affecting performance and avoid worse situations.
