Solution

1. Preparation

Gather tools and materials.
- Tools Required: Fuse puller or needle-nose pliers, multimeter
- Parts Required: Replacement fuses of the appropriate amperage
Ensure the vehicle is turned off and parked on a level surface.

2. Accessing the Fuse Boxes

Open the driver's side door and locate the fuse box cover under the dashboard.
Remove the cover by gently pulling it off or unscrewing any retaining screws.
Locate the engine compartment fuse box, typically near the battery, and remove its cover.

3. Inspecting the Fuses

Refer to the fuse diagram in the owner's manual to identify the fuses related to the non-functioning components.
Using the fuse puller or needle-nose pliers, carefully remove each fuse for inspection.
Visually check each fuse for a broken filament or melting.
If the fuse appears intact, use a multimeter set to the continuity setting to test it, placing one probe on each end of the fuse.

4. Replacing Blown Fuses

If a fuse is found to be blown, note the amperage rating and replace it with a new fuse of the same rating.
Push the new fuse firmly into the slot until it is seated properly.
Repeat for any other blown fuses identified.

5. Reassembly

Once all inspections and replacements are completed, replace the covers on both fuse boxes.
Ensure all covers are securely fastened.
