Why do the hazard lights of the Besturn B70 not flash when locking the car?

The reasons why the hazard lights of the Besturn B70 do not flash when locking the car include the door not being closed tightly, not being shifted to P gear, or a blown fuse. Below is a detailed introduction to the causes and solutions for this issue: Door not closed tightly: If the door is not closed tightly, the car's central locking system will issue a reminder, and the car will not be locked at this time, so the hazard lights naturally will not flash. Solution: Close the door tightly again. Not shifted to P gear: For the Besturn B70 model, the vehicle's computer defaults to requiring the gear to be in P when turning off and locking the car. If it is not in P gear, the car cannot be locked. Blown fuse: Check whether the hazard light fuse in the fuse box has blown. Replace it if necessary.

My Bestune B70's hazard lights don't flash when locking the car recently, which is quite annoying. I think the most common causes are a blown fuse or a burnt-out bulb, as I've encountered similar issues with my old car before. That time, the inspection revealed a melted fuse, and it was easily fixed by replacing it. Another possibility is poor wiring contact, especially in the car locking system linkage, where rust from humid weather can cause circuit breaks. The hazard lights not flashing isn't just about the confirmation signal when locking the car; if they fail during an emergency, it could lead to accidents due to misoperation, which is quite dangerous. I suggest first checking the manual to locate the fuse box and trying to replace the bulb or fuse yourself. If that doesn't work, take it to a 4S shop for the mechanics to check the wiring or relay. Don't delay addressing it to avoid minor issues turning into major repairs. Also, be careful not to let water splash into the light area when washing the car to prevent problems before they occur.

I've also pondered the issue of the hazard lights not flashing when locking the car. Based on my experience tinkering with cars, it's mostly due to electrical circuit failures. Common causes include burnt-out bulbs from aging, blown fuses due to overload, or corroded relay contacts affecting switching. Short circuits are another frequent culprit - I once found wires chewed through by rodents during repairs, interrupting current flow. Diagnosis isn't difficult; using a multimeter to test circuit resistance or voltage can pinpoint the issue. If the control module fails, professional diagnostic equipment becomes necessary. As safety indicators, malfunctioning hazard lights pose significant risks, especially with impaired nighttime parking warnings that may lead to rear-end collisions. I recommend regular engine compartment cleaning to prevent component corrosion and maintain system stability.

The hazard lights don't flash when locking the car, I've encountered this situation before. I think it might be caused by a burnt-out bulb or a fuse issue. Check the body control module, as incorrect settings could also lead to this. The Besturn B70 has a central control system; if it's supposed to flash when locking but doesn't, there might be a software conflict or sensor malfunction. I recommend taking it to a 4S shop for a technician to inspect, to avoid making things worse by tinkering yourself. By the way, lights not working might affect the anti-theft function, so pay extra attention to safety when parking. Timely repairs can save you trouble.
