- Clean battery terminals with a wire brush if corrosion is present.
Reconnect Battery
- Reconnect battery terminals securely and check for tightness.

3. Fuse Inspection

Locate Fuse Box
- Refer to the owner’s manual for the exact location of the fuse box.
Check Fuses
- Remove and visually inspect fuses related to the problematic systems.
- Replace any blown fuses with the same amperage rating.

4. Wiring Inspection

Visual Inspection
- Examine wiring harnesses near connectors for signs of wear, fraying, or corrosion.
Repair as Necessary
- Use electrical tape or heat shrink tubing to insulate and protect damaged wires.

5. Software Update

Check for Updates
