Solution

1. Preparation

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

2. Remove Blown Fuses

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Use a fuse puller or pliers to carefully remove the blown fuses.
Inspect the removed fuses to confirm they are blown (broken filament or discoloration).

3. Replace Fuses

Obtain replacement fuses of the same amperage as the blown fuses (refer to the fuse diagram for specifications).
Insert the new fuses firmly into their respective slots in the fuse box.

4. Check Electrical Components

Reconnect the battery's negative terminal.
Turn on the vehicle and test the previously affected electrical components for proper functionality.
If necessary, replace any additional blown fuses and retest.

5. Inspect and Repair Wiring

If fuses continue to blow, inspect the wiring harnesses and connectors for damage.
Repair or replace any damaged wires or connectors to prevent future fuse issues.
