Solution

1. Preparation

Gather all tools and parts required for repair.
Disconnect the negative terminal of the battery to ensure safety during electrical work.

2. Inspect and Replace Bulbs

Sub-steps:
1. Open the trunk and remove the access panel to the tail light assembly.
2. Twist the bulb socket counterclockwise to remove it from the assembly.
3. Pull the old bulb straight out and replace it with a new bulb.
4. Reinsert the bulb socket into the assembly and twist it clockwise to secure.
5. Replace the access panel back into position.

3. Check and Replace Fuse

Tools Required: Fuse puller or pliers
Sub-steps:
1. Locate the fuse box under the dashboard or in the engine compartment.
2. Identify the tail light fuse using the fuse diagram on the cover.
3. Remove the fuse using the fuse puller or pliers.
4. Inspect the fuse for continuity; replace with a new fuse of the same amperage if blown.
5. Reinsert the fuse into the fuse box.

4. Test Tail Light Socket

Tools Required: Multimeter
Sub-steps:
1. Set the multimeter to the DC voltage setting.
2. Turn on the headlights and probe the tail light socket with the multimeter leads.
3. Check for voltage (typically around 12 volts); if voltage is present, the socket is functioning.
4. If no voltage is detected, further inspect the wiring harness.

5. Repair Wiring Harness (if necessary)

Sub-steps:
1. Visually inspect the wiring harness for any signs of wear, corrosion, or disconnection.
2. If damage is found, cut out the damaged section and splice in new wire using electrical connectors.
3. Ensure all connections are secure and insulated with electrical tape or heat shrink tubing.
