What Causes One Side of the Car Headlight to Work While the Other Doesn't?
1 Answers
It could be due to a blown fuse, a short circuit in the bulb, or the bulb being burnt out. Generally, if only one headlight is not working, it is most likely because the bulb has burned out. If both headlights are not working simultaneously, it may be due to a blown fuse, both bulbs burning out at the same time, aging and breaking of the wiring, or loose terminals. However, the probability of these two phenomena occurring is extremely low. Solution: 1. Locate the fuse box: The vehicle's circuit fuse box is usually fixed under the hood in the engine compartment, near the fender. The exact location varies depending on the vehicle model. 2. Open the cover and inspect: Once you find the circuit fuse box, open the cover. You will see various fuses and controllers of different amperages for different electronic devices. The back of the cover has a corresponding diagram, which can help you locate the fuses for the left and right headlights. Use the included clip to pull them out and observe whether the contact points at both ends are melted. If there is a gap, it means the fuse is bad. If the nodes are normal, reinsert the fuse as it was and proceed to check both headlights. It is recommended to seek repair at a 4S shop if you encounter this issue.
