Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is turned off and parked safely.
Disconnect the negative battery cable to prevent electrical shocks.

2. Locate the Fuse Box

Open the driver's side door and remove the fuse box cover located on the left side of the dashboard.
Consult the owner's manual for specific fuse box layout and fuse assignments.

3. Inspect and Replace Fuses

Visually check each fuse using the diagram on the fuse box cover for identification.
For any suspected blown fuses, remove them using a fuse puller or pliers.
Test with a multimeter for continuity: Set to the continuity setting, touch probes to each end of the fuse. No beep indicates a blown fuse.
Replace blown fuses with new ones of the same amperage rating (found on the fuse itself).

4. Reassemble and Test

Reattach the fuse box cover securely.
Reconnect the negative battery cable.
Start the vehicle and test the previously malfunctioning electrical components to ensure they work correctly.
