Solution

1. Preparation

Gather tools: a fuse puller or needle-nose pliers, multimeter, and owner's manual.
Ensure the vehicle is turned off and keys removed from the ignition.

2. Access the Fuse Box

Under-Dashboard Fuse Box:
- Open the driver’s side door and locate the fuse panel cover beneath the dashboard.
- Remove the cover by pulling it off or unscrewing it, depending on the design.
Engine Compartment Fuse Box:
- Open the hood and secure it with the prop rod.
- Locate the fuse box, usually near the battery.
- Remove the cover by pressing the tabs or unscrewing it, as applicable.

3. Inspect and Replace Fuses

Use the fuse puller or needle-nose pliers to remove the suspected blown fuse.
Check the fuse visually for a broken filament or discoloration.
If using a multimeter, set it to the continuity setting and touch the probes to the terminals of the fuse. A reading indicates a good fuse.
If the fuse is faulty, replace it with a new fuse of the same amperage (as indicated on the fuse).
Reinsert the fuse securely back into the fuse box.

4. Reassemble

Replace the fuse box cover by snapping or screwing it back into place.
Close the hood securely if the engine compartment fuse box was accessed.
