How to Solve the Issue of Turn Signals Not Flashing When Locking/Unlocking the Car
3 Answers
Inspect and verify the corresponding fuse box to ensure there are no faults with the fuse box and its components. It was discovered that the turn signal flashing function when locking/unlocking the car is a user-customizable option. Users can adjust this setting through the vehicle settings, with the default being the enabled state.
I just encountered a similar situation where the hazard lights don't flash when locking/unlocking the car, which is indeed frustrating. As a car owner, I'd first try to troubleshoot basic things myself: Are the bulbs burnt out? Check the trunk and rear light areas, then try replacing with new bulbs. The fuse box is usually located in the engine compartment or under the driver's seat - consult the manual to identify which fuse controls the flashers and replace it with the same specification if blown. If that doesn't work, it might be loose wiring or a short circuit - don't force repairs as there's risk of electric shock. Hazard lights are crucial for avoiding rear-end collisions during emergency braking, so leaving them unrepaired poses significant safety risks. Best to note details like whether the lights completely fail or intermittently malfunction, then drive directly to the 4S shop for comprehensive diagnostics. I recommend regular maintenance checks on vehicle lighting - prevention is far more convenient and cost-effective than repairs.
I usually enjoy tinkering with automotive electronics. If the hazard lights don't flash when locking the car, you need to start troubleshooting from the electrical circuit. First, check the fuse: a blown fuse is the easiest to fix. Then locate the relay in the engine compartment box to see if the contacts are damaged, and replace it with a matching model. If the control module or switch fails, professional tools may be required for detection. When using a multimeter to measure voltage yourself, avoid careless contact to prevent short circuits that could damage the car. Hazard lights aren't just for locking signals; they're crucial for emergency warnings, making it high-risk not to repair them. I've learned a tip: observe if other lights are functioning normally to help identify the problem source. Get it repaired as soon as possible to prevent minor issues from turning into major repairs.
