Remove the cover and locate the radio fuse (refer to the fuse diagram).
Use a fuse puller or pliers to remove the fuse and visually inspect it for damage.
- Sub-step: If blown, replace with a new fuse of the same amperage (typically 10A or 15A).
Safety Warning: Ensure the ignition is off when handling fuses.

3. Inspect Wiring Connections

Remove the trim panel surrounding the radio using trim removal tools to avoid damage.
Unscrew and remove the radio unit from the dashboard.
Inspect the wiring harness for any loose or corroded connections.
- Sub-step: If loose, secure the connector firmly back into place.
- Sub-step: If damaged, replace the wiring harness or repair the connections as necessary.

4. Test the Radio Unit

Before reinstalling the radio, reconnect the wiring harness and turn the ignition to the "On" position.
Check if the radio powers on. If it does, proceed to reinstall the unit.
If it still does not power on, consider replacing the radio unit.

5. Reassemble

Carefully reinsert the radio into the dashboard and secure it with screws.
Replace the trim panel, ensuring it is properly seated.
Safety Warning: Ensure all tools are removed from the vehicle before closing the panels.
