Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Inspect and Replace Fuses

Tools Required: Fuse puller or needle-nose pliers
Identify the fuse for the radio in the fuse box (refer to the owner's manual for the exact location).
Remove the fuse and inspect it; if the metal strip is broken, replace it with a new fuse of the same amperage (typically 10A or 15A).
Reinstall the fuse and reconnect the battery.

3. Check Power at the Radio

Tools Required: Multimeter
Remove the radio from the dashboard (use a trim removal tool to avoid damaging the panels).
Disconnect the harness connector from the back of the radio.
Set the multimeter to measure DC voltage and check for power at the radio connector.
If no power is detected, trace the wiring back to the fuse box and ignition switch for issues.

4. Inspect Ground Connection

Tools Required: Socket set
Locate the ground wire connected to the radio (usually a black wire in the harness).
Ensure the ground connection is tight and clean; if corroded, clean the contact point or replace the ground wire.

5. Reconnect and Test

After verifying all connections and replacing any faulty components, reassemble the radio and dashboard panels.
Reconnect the negative battery terminal.
Turn on the vehicle and check if the radio functions properly.
