* Stop Lamps: This is the most likely heading.
* Tail Lamps: Brake lights often share a fuse with taillights.
* Accessory/Power: A less likely but possible scenario is the problem lies in a main power fuse that affects multiple systems, including the brake lights.
To find the correct fuse(s):
1. Consult your owner's manual: This is the most accurate source. Look for diagrams showing fuse locations and what each fuse controls. Pay close attention to diagrams, as they'll show which fuse(s) relate to the brake light circuit(s).
2. Check multiple fuses: Don't just check one fuse labeled "Stop Lamps" (if you even find one). Check all fuses related to the tail lights, brake lights, and possibly even a main power fuse if the others are fine.
3. Look for blown fuses: A blown fuse will appear visibly damaged (broken filament inside the glass).
4. Test the fuses: Even if a fuse looks okay, use a multimeter to verify continuity. This ensures the fuse isn't partially blown and still causing problems.
If you can't find the solution in the manual or by checking the fuses, consider:
* Brake light switch: This switch is activated when you press the brake pedal. A faulty switch can prevent the brake lights from functioning.
* Wiring problems: A short circuit or damaged wiring could be the issue. This would require more in-depth electrical diagnosis.
* Bulbs: Check that the brake light bulbs themselves are still functioning.
Because the brake light system is tied to safety, it's best to have a qualified mechanic diagnose and repair this if you cannot find the problem yourself. Driving with non-functional brake lights is extremely dangerous.
