Diagnostic Steps

1
Locate the fuse box in the cabin and the fuse box under the hood.
2
Check the owner's manual for the fuse diagram to identify the fuses related to the malfunctioning components.
3
Visually inspect each fuse for signs of damage, such as a broken wire or discoloration.
4

5
Replace any blown fuses with fuses of the same amperage rating.

Solution

1. Preparation

Gather necessary tools, including a multimeter and a fuse puller.
Ensure the vehicle is off and parked on a flat surface.

2. Locate the Fuse Boxes

Cabin Fuse Box: Open the driver's side door and remove the cover located on the left side of the dashboard.
Engine Compartment Fuse Box: Open the hood and locate the fuse box, typically near the battery.

3. Inspect the Fuses

Refer to the owner's manual for the fuse diagram.
Use the fuse puller to gently remove each fuse one at a time.
Inspect fuses visually for any signs of damage; a blown fuse will have a broken filament inside.

4. Test the Fuses (if necessary)

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

5. Replace Blown Fuses

Remove any blown fuses using the fuse puller.
Replace with a new fuse of the same amperage rating, ensuring it is properly seated in the fuse socket.

6. Reassemble and Test

Reattach the covers for both the cabin and engine compartment fuse boxes.
Start the vehicle and check if the previously malfunctioning components are operational.
