1. Faulty bulb or socket: A faulty bulb or socket can cause a short circuit, which can blow the fuse. Check the bulbs in the tail lights and dashboard to make sure they are not loose or damaged. If they are, replace them with new ones.
2. Damaged wiring: Damaged wiring can also cause a short circuit. Look for any signs of damage to the wiring, such as cuts, nicks, or burns. If you find any damaged wiring, have it repaired by a qualified mechanic.
3. Bad tail light switch: The tail light switch is responsible for turning on the tail lights when the headlights are turned on. If the tail light switch is faulty, it can cause the tail lights to stay on even when the headlights are off, which can blow the fuse. Check the tail light switch to make sure it is working properly.
4. Faulty fuse: The fuse itself may be faulty. Try replacing the fuse with a new one of the same amperage. If the new fuse also blows, then there is likely a problem with the wiring or a component in the circuit.
If you are unable to identify the cause of the problem, you should take your vehicle to a qualified mechanic for diagnosis and repair.
