Solution

1. Preparation

Tools Required: Multimeter, fuse puller, screwdriver set, wiring diagram (if available).
Disconnect the negative terminal of the battery to prevent any electrical short circuits during the repair.

2. Inspect and Replace Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the cover and identify the radio fuse using the diagram on the cover or vehicle's manual.
Use a fuse puller to remove the fuse and check for continuity using a multimeter.
- If it is blown, replace it with a fuse of the same amperage (refer to the manual for the correct rating).
Reinstall the fuse and cover.

3. Check Wiring Connections

Reconnect the negative battery terminal.
Remove the radio unit from the dashboard using a screwdriver.
Inspect the wiring harness connection to the radio for any loose or corroded wires.
Secure any loose connections and repair any damaged wiring using appropriate electrical tape or connectors.

4. Test Radio Functionality

Reconnect the radio to its wiring harness.
Reinstall the radio into the dashboard.
Reconnect the negative battery terminal once more.
Turn on the ignition and check if the radio powers on and functions correctly.
