1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Replace Fuse

Tools Required: Fuse puller or pliers
Locate the fuse box; check the owner's manual for the radio fuse location.
Remove the radio fuse and inspect it for continuity. Replace it if blown with the same amperage rating.

3. Check and Repair Wiring

Tools Required: Multimeter, wire strippers, electrical tape
Reconnect the negative battery terminal.
Disconnect the radio wiring harness.
Using a multimeter, check for power at the harness connector. If no power is detected, trace the wiring back to the fuse box for any breaks or shorts.
