Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to ensure safety.
Tools Required: Socket set, multimeter, OBD-II scanner.

2. Inspect and Replace the Bulb

Open the tailgate and locate the tail light assembly.
Remove the screws or clips securing the tail light assembly.
Carefully pull the tail light assembly away from the vehicle.
Twist and remove the damaged bulb from the socket.
Replace with a new bulb of the same type (typically a 7443 for tail lights).
Reassemble the tail light assembly by reversing the removal steps.

3. Check and Replace the Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Identify the fuse for the tail lights (refer to the fuse diagram on the cover).
Remove the fuse using a fuse puller or pliers.
Inspect the fuse to see if it is blown (the wire inside will be broken).
Replace with a new fuse of the same amperage rating.

4. Verify and Repair Wiring

Reconnect the negative terminal of the battery.
Use a multimeter to test the voltage at the tail light socket.
If no voltage is present, visually inspect the wiring harness for any damage or disconnection.
Repair any damaged wires using appropriate electrical connectors and tape.
