Why Won’t My Hazard Lights Turn Off?
There are some main problems with your hazard lights:
1. The Fuse Is Blown
If you have an older car, you may have replaced the fuse in the trunk. They are usually small rectangular blocks that look like candy. If one of them explodes, no power is supplied for the lights.
2. Relay Switch Faulty
This is an electrical switch that takes power from a fuse and connects it to the front and back of the car. If the relay switch is faulty, you may hear a slight click when trying to turn it off, but it will not turn off completely. You will need to replace this part to get it working properly again.
3. Car Doors
If your vehicle has a sensor that alerts you when a vehicle door is open, a hazard warning light will sound if one or more vehicle doors are not properly locked. To diagnose this, if all doors are properly closed and the lights are off, the vehicle’s door hinges are defective. Then you can fix the loop so that the same problem doesn’t happen again.
