Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is turned off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Replace Brake Light Bulbs

Remove the tail light assembly by unscrewing the fasteners.
Disconnect the electrical connector from the back of the tail light assembly.
Twist and remove the old brake light bulbs from their sockets.
Install new bulbs, ensuring they are securely seated.
Reconnect the electrical connector and reattach the tail light assembly.

3. Check and Replace the Brake Light Fuse

Locate the fuse box and find the diagram that indicates the brake light fuse.
Remove the fuse and inspect it for continuity; replace with a new fuse of the same amperage if necessary.
Reassemble the fuse box cover.

4. Test or Replace the Brake Light Switch

Locate the brake light switch mounted on the brake pedal assembly.
Disconnect the wiring harness from the switch.
Use a multimeter to check for continuity when the brake pedal is pressed.
If the switch is faulty, remove it by unscrewing any mounting fasteners and replace it with a new switch.

5. Inspect and Repair Wiring

Visually inspect the wiring harness for any signs of damage or corrosion.
Use a multimeter to test for continuity along the wiring leading to the brake lights.
Repair any damaged wiring by cutting out the affected sections and soldering in new wire or using appropriate connectors.
