Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, fuse puller or pliers, owner's manual.
Ensure the vehicle is parked on a level surface and is turned off.

2. Access the Fuse Panel

Locate the fuse panel; typically found under the dashboard on the driver’s side or in the engine compartment.
Open the cover of the fuse panel by releasing the clips or screws.

3. Inspect the Fuses

Identify the fuse corresponding to the faulty component using the diagram on the fuse panel cover or the owner's manual.
Carefully remove the fuse using a fuse puller or pliers.

4. Test the Fuse

Visual Inspection: Check for a broken filament within the fuse. A blown fuse will have a gap or a darkened appearance.
Continuity Test: Set the multimeter to the continuity setting. Place one probe on each metal end of the fuse. If the multimeter beeps or shows continuity, the fuse is good; if not, it is blown.

5. Replace the Fuse

If the fuse is blown, replace it with a new fuse of the same amperage rating.
Ensure the new fuse is seated properly in the fuse holder.

6. Reassemble and Test

Reattach the fuse panel cover securely.
Start the vehicle and test the previously affected electrical components to confirm functionality.
