Solution

1. Preparation

Tools Required:
- Screwdriver (if needed to access the fuse box)
- Multimeter
- Replacement fuses (as necessary)
Safety Warnings:
- Ensure the vehicle is turned off and keys are removed from the ignition before proceeding.

2. Locate the Fuse Box

Open the driver’s side door and locate the fuse box, which is typically situated on the left side of the dashboard or under the hood.
Consult the owner's manual for the exact location if necessary.

3. Access the Fuse Box

If the fuse box is covered, use a screwdriver to remove any screws or clips.
Carefully lift the cover off to expose the fuses.

4. Inspect the Fuses

Refer to the fuse diagram printed on the cover or in the owner’s manual.
Identify the fuses related to the components that are not functioning.
Look for any blown fuses (the metal filament inside the fuse will be broken).

5. Test the Fuses

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

6. Replace Blown Fuses

Remove any blown fuses and replace them with new fuses of the same amperage rating.
Ensure the new fuses are seated properly in their sockets.

7. Reassemble and Close the Fuse Box

Replace the cover of the fuse box and secure it with screws or clips if necessary.
Close the driver’s side door.
