Solution

1. Preparation

Gather tools: multimeter, fuse puller or needle-nose pliers.
Ensure the vehicle is parked on a flat surface and engine is off.

2. Locate the Fuse Box

Open the driver's side door and locate the fuse box, typically found under the dashboard or near the steering column.
Refer to the owner's manual for the exact location and a diagram of the fuses.

3. Inspect the Fuses

Remove the fuse box cover by gently pulling it off.
Identify the specific fuses related to the malfunctioning components using the fuse diagram.
Use your fingers or a fuse puller to carefully remove the fuses from their sockets.

4. Test the Fuses

Set the multimeter to the continuity setting.
Place one probe on each end of the fuse terminals; a beep or a reading indicates a good fuse.
If there is no continuity, the fuse is blown and needs replacement.

5. Replace Blown Fuses

Remove the blown fuse from the fuse box.
Insert a new fuse of the same amperage rating as indicated on the fuse diagram.
Ensure the fuse is seated properly in the socket.

6. Reassemble and Test

Replace the fuse box cover securely.
Start the vehicle and test the previously malfunctioning electrical components to confirm they are operational.
