Solution

1. Preparation

Gather tools and materials needed for the repair.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Inspect and Replace Bulbs

Remove the rear light assembly by unscrewing the retaining screws and gently pulling it out.
Inspect each bulb socket for corrosion or damage. If necessary, replace any burnt-out bulbs with new ones.
Reinstall the light assembly and secure it.

3. Check and Replace Fuses

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Refer to the owner's manual for the specific fuse related to the rear lights.
Remove the fuse and inspect it; if it’s blown, replace it with a fuse of the same amperage rating.

4. Test and Replace the Brake Pedal Switch

Locate the brake pedal switch, typically near the top of the brake pedal.
Disconnect the wiring harness from the switch.
Use a multimeter to check for continuity. If there’s no continuity when the pedal is pressed, replace the switch.
Reconnect the switch and ensure it’s properly aligned.

5. Verify Wiring and Connections

Inspect the wiring harness leading to the rear lights for any signs of fraying, corrosion, or disconnections.
Repair any damaged wires with electrical tape or connectors as needed.
Ensure all connections are secure and free from corrosion.
