Solution

1. Preparation

Gather tools: flathead screwdriver or fuse puller (if needed).
Ensure the vehicle is off and the keys are removed from the ignition.
Wear safety gloves to protect your hands.

2. Locate the Fuse Box

Open the driver's side door and remove the cover of the fuse box under the dashboard.
Alternatively, for the engine compartment fuse box, open the hood and secure it with the prop rod.

3. Identify and Remove the Fuse

Refer to the fuse diagram on the cover or in the owner’s manual to locate the specific fuse for the component that is malfunctioning.
Use a fuse puller or flathead screwdriver to gently pry the fuse out of its slot.

4. Inspect the Fuse

Check the fuse visually for any signs of damage. A blown fuse will often have a broken filament or appear discolored.
If necessary, use a multimeter set to the continuity setting to test the fuse. Place one probe on each end of the fuse; a reading indicates it's good, while no reading indicates it's blown.

5. Replace the Fuse

If the fuse is blown, replace it with a new fuse of the same amperage rating (indicated on the fuse).
Push the new fuse firmly into the correct slot until it is seated securely.

6. Reassemble and Test

Replace the fuse box cover securely.
Start the vehicle and test the component to ensure it is functioning properly.
