Where is the fuse for the left and right turn signals?

Under the headlight switch. There are usually two fuse boxes in a car, one located on the right side of the engine compartment, mainly responsible for the safety of external electrical components such as the ECU, windshield washer, lights, horn, ABS, etc. Below is relevant information about turn signals: 1. Function of turn signals: Turn signals are controlled by electronic devices but still use an audible simulation of the relay's clicking sound to remind the driver that the turn signal is flashing. They are important indicators that are activated when the vehicle is turning to alert surrounding vehicles and pedestrians. 2. Types of turn signals: Turn signals use flashers to achieve blinking lights. They can mainly be divided into three types: resistance wire type, capacitor type, and electronic type. The resistance wire type can be further divided into thermal wire type (electrothermal) and vane type (spring-loaded), while the electronic type can be divided into hybrid type (with contact relay and electronic components) and fully electronic type (without relay).
As someone who frequently repairs cars, I'm quite familiar with the location of the turn signal fuses. They are usually found in the main fuse box, which can be in one of two places: inside the car, behind a small cover on the lower left corner of the dashboard under the steering wheel—just open the door and bend down to see it; or in a large box on the right side of the engine compartment—lift the hood and look around. The exact location depends on the car model. For example, my Toyota has it inside the car, while my friend's Ford has it in the engine compartment. Common reasons for a blown fuse include circuit overload or a short circuit in the bulb—such as when you've added extra electrical devices, increasing the load. Handling it yourself is quite simple: check the fuse diagram in the owner's manual, locate the corresponding fuse, and replace it with a new one of the same rating to avoid damaging other circuits. Safety first—a broken turn signal is dangerous and can easily lead to accidents. I recommend keeping a few 15A fuses in the glove box for emergencies—it saves money. Regularly checking for aging wiring also helps prevent issues.
