1. Check the Fuses:
- Locate the fuse box. It should be situated in the driver side footwell, behind a plastic cover.
- Identify the fuses that control the brake lights and turn signals. Refer to your vehicle's owner's manual for the specific fuse locations.
- Pull out the fuses and visually inspect them for any breaks or melted sections. If a fuse is blown, replace it with a new fuse of the same amperage.
2. Inspect the Bulbs:
- Remove the bulb housing assembly for the rear brake lights and turn signals.
- Carefully inspect the bulbs for any signs of damage, discoloration, or broken filaments.
- If a bulb is damaged, replace it with a new bulb of the correct type and wattage.
3. Check the Socket:
- Examine the bulb socket for any signs of corrosion or damage. Clean the socket if necessary using a wire brush or electrical contact cleaner.
- Ensure that the bulb is making proper contact with the metal terminals inside the socket.
4. Test the Brake Light Switch:
- Locate the brake light switch, usually situated near the brake pedal.
- Press the brake pedal and observe if the brake lights come on.
- If the brake lights do not illuminate when the brake is pressed, the brake light switch may be faulty and needs replacing.
5. Check the Turn Signal Switch:
- Engage the turn signal lever and observe if the corresponding turn signal indicator on the dashboard illuminates.
- If the indicator lights do not come on, or if the turn signals do not work, the turn signal switch could be faulty and in need of replacement.
6. Examine the Wiring:
- Look for any visible signs of damage, breakage, or exposed wires in the wiring harness that leads to the rear lights.
- If you notice any damaged wires, they may need to be repaired or replaced.
7. Check Grounds:
- Ensure that the ground connections for the rear lights are clean and secure. Poor grounding can cause electrical issues.
If you have gone through these steps and the brake lights and turn signals still do not work, it is recommended to seek the assistance of a qualified automotive electrician or mechanic who can further diagnose the issue and perform any necessary repairs.
