Solution

1. Preparation

Gather tools and parts needed for the repair.
Tools Required:
- Multimeter
- Screwdriver set
- Socket set
- Replacement bulbs (if necessary)
- Replacement fuses (if necessary)

2. Inspect and Replace Bulbs

Remove the rear light assembly by unscrewing the mounting screws.
Pull the light assembly out carefully.
Check each bulb: if any are burnt out, replace them with the appropriate type (e.g., 7443 for tail lights).
Reassemble the light assembly and secure it back in place.

3. Check and Replace Fuses

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the fuses related to the rear lights (refer to the fuse diagram on the fuse box cover).
Remove the fuse and inspect it. If it’s blown, replace it with a new fuse of the same amperage.
Close the fuse box securely.

4. Test Voltage at Bulb Sockets

With the rear lights activated, use a multimeter to test for voltage at the bulb socket.
If there is no voltage, trace back to the wiring harness to check for breaks or shorts.

5. Inspect Wiring and Ground Connections

Visually inspect the wiring leading to the rear light assembly for fraying or damage.
Ensure ground connections are clean and secure at the rear of the vehicle. If corroded, clean and reconnect.
