Solution

1. Preparation

Gather tools: fuse puller, multimeter, replacement fuses, and a flashlight.
Ensure the vehicle is turned off and parked on a level surface.

2. Locate the Fuse Box

Open the driver's side door and locate the fuse box, typically found under the dashboard or in the glove compartment.
Use the owner's manual to confirm the exact location.

3. Inspect Fuses

Remove the cover of the fuse box and visually inspect each fuse for any signs of damage, including a broken wire inside the fuse or discoloration.
Use a fuse puller to safely remove fuses for closer inspection if necessary.

4. Test Fuses with Multimeter

Set the multimeter to the continuity setting.
Touch the probes to the terminals of each fuse; a continuous beep indicates a functioning fuse, while silence indicates a blown fuse.

5. Replace Blown Fuses

Remove any identified blown fuses using the fuse puller.
Insert new fuses of the same amperage as the original (check the markings on the fuse).
Ensure the fuses are seated correctly in their slots.

6. Reassemble and Test

Replace the fuse box cover securely.
Turn on the vehicle and test the previously malfunctioning electrical components to confirm they are operational.
