Solution

1. Preparation

Gather necessary tools:
- Flathead screwdriver
- Multimeter
- Pair of needle-nose pliers (optional)
Ensure the vehicle is parked securely and the ignition is off.

2. Access the Fuse Box

Locate the fuse box, typically found under the dashboard on the driver’s side or in the engine compartment.
Remove any panel covers using a flathead screwdriver if necessary.

3. Inspect and Test Fuses

Visually inspect each fuse for a broken filament or discoloration.
For further confirmation, use a multimeter:
- Set the multimeter to continuity mode.
- Touch the probes to both ends of the fuse. A continuous beep indicates a good fuse; no beep indicates a blown fuse.

4. Replace Blown Fuses

Use needle-nose pliers or your fingers to pull out the blown fuse.
Refer to the owner’s manual to ensure you replace it with a fuse of the same amperage.
Insert the new fuse securely into the corresponding slot.

5. Reassemble and Test

Replace any cover panels that were removed to access the fuse box.
Turn on the vehicle and check the function of the previously affected electrical components.
