Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is turned off.
Disconnect the negative battery terminal to prevent electrical shock.

Use the fuse puller or a pair of needle-nose pliers to carefully remove the suspected blown fuse.
Inspect the fuse visually; a broken filament indicates it is blown.

4. Replace the Fuse

Select a new fuse of the same amperage (verify in the owner's manual for the correct rating).
Insert the new fuse firmly into the correct slot.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
