Solution

1. Preparation

Tools Required: Fuse puller, multimeter, owner's manual.
Ensure the vehicle is turned off and parked on a level surface.
Disconnect the negative battery terminal to prevent electrical shock.

2. Locate Fuse Boxes

Sub-steps:
1. Open the hood and identify the engine compartment fuse box, typically located near the battery.
2. Open the driver's side door and locate the interior fuse box, which is usually found under the dashboard, near the steering column.

3. Identify and Inspect Fuses

Sub-steps:
1. Refer to the owner's manual for the fuse diagram that indicates the function of each fuse.
2. Use a fuse puller to remove each fuse related to the suspect electrical components.
3. Inspect the fuse visually; look for a broken filament or discoloration.

4. Test with Multimeter

Sub-steps:
1. Set the multimeter to the continuity setting.
2. Place the probes on each end of the fuse.
3. If the multimeter beeps or shows continuity, the fuse is good; if it does not, the fuse is blown.

5. Replace Blown Fuses

Sub-steps:
1. Replace any blown fuses with new fuses of the same amperage rating.
2. Ensure the new fuse is seated correctly in the fuse box.

6. Reconnect Battery

Reconnect the negative battery terminal after all inspections and replacements are complete.
