Solution

1. Preparation

Gather necessary tools: fuse puller or needle-nose pliers, multimeter.
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; it is typically situated under the dashboard on the left side.
Alternatively, check the engine compartment for the main fuse box.

3. Inspect the Fuses

Remove the fuse box cover by unclipping it.
Use a fuse puller or needle-nose pliers to gently pull out the fuse corresponding to the malfunctioning component.
Check the fuse visually for a broken filament or discoloration indicating a blown fuse.

4. Testing Fuses with a Multimeter

Set the multimeter to the continuity setting.
Place one probe on each end of the fuse.
If the multimeter beeps or shows continuity, the fuse is intact; if not, it is blown.

5. Replace the Blown Fuse

If a blown fuse is found, replace it with a new fuse of the same amperage rating (found on the fuse itself or in the owner’s manual).
Ensure the new fuse is seated properly in the fuse box.

6. Final Steps

Reattach the fuse box cover securely.
Start the vehicle and check if the previously malfunctioning component is now operational.
