1. Preparation

Gather tools: OBD-II scanner, multimeter, screwdriver set, and replacement fuses if needed.
Ensure the vehicle is parked in a safe location with the engine off.
Disconnect the battery for safety.

2. Inspect and Replace Fuses

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the fuse panel cover and identify the rear defroster fuse.
