Solution

1. Preparation

Gather all necessary tools.
Ensure the vehicle is turned off and parked safely.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Access the Fuse Box

Tools Required: None
Locate the fuse box under the dashboard on the driver's side and in the engine compartment.
Remove any clips or screws securing the fuse box cover.
Carefully lift the cover off to expose the fuses.

3. Inspect the Fuses

Tools Required: None or multimeter (if needed)
Refer to the fuse diagram on the back of the cover or in the owner's manual to locate the relevant fuse.
Remove the fuse using a fuse puller or needle-nose pliers.
Visually inspect the fuse for damage. If it appears burnt or broken, it needs replacing.
If unsure, use a multimeter set to continuity mode. Touch the probes to each end of the fuse; a continuous beep indicates the fuse is good.

4. Replace the Fuse (if necessary)

Parts Required: New fuse of the same amperage
Remove the damaged fuse and discard it.
Insert a new fuse of the same amperage into the same slot.
Ensure it is seated firmly.

5. Reassemble and Test

Reattach the fuse box cover, ensuring all clips or screws are secured.
Reconnect the negative battery terminal.
Start the vehicle and test the electrical components to ensure they are functioning properly.
