What is the reason for the Cruze's low beam not working while the high beam is on?

Cruze if the high beam is on, but the low beam is not working, it may be that the low beam filament is burned out. You can see this by disassembling it, and just replace the bulb. However, if both low beams are not working and the filaments are not burned, you should check if the switch has power. If there is no issue, then check if the fuse is normal. Here is some additional information: 1. Bulbs are divided into headlights, middle lights, and small lights. Headlights refer to the front headlights, mainly including quartz lamps and xenon lamps; middle lights refer to brake lights, turn signals, etc.; small lights refer to interior lights, instrument panel lights, indicator lights, and width lights. 2. Rotating the lever head once turns on the small lights, and twice turns on the headlights. The lever can be pushed up and down. When in the middle position, pushing up switches between low and high beams, and releasing the lever automatically returns it to the middle position. Pushing down switches to the high beam, and you can hear a click sound when pushing down. Releasing the lever does not return it to the original position.
I also encountered this issue when driving my Cruze, where the low beams don't work but the high beams do. It's likely that the low beam filament is burnt out individually, since there are two filaments in the same bulb, and the fact that the high beams still work indicates that the bulb socket or power supply is basically fine. First, check the low beam fuse in the fuse box. If it's blown, just replace it with a new one—it's simple enough to do yourself. If the bulb isn't faulty, it might be due to worn contacts in the combination switch or poor wiring connections causing current to only reach the high beams. Once, I just had a blown fuse, spent 5 yuan on a new one, replaced it, and the lights worked again. Driving at night without low beams is very dangerous, so you should troubleshoot it promptly and not take it lightly. It's best to have a professional shop do a comprehensive check.
