4. Hold the fuse up to the light to see if the metal strip inside is broken. If it is, the fuse is blown and needs to be replaced.

Replacing a fuse is quick and inexpensive. You can find replacement fuses at most auto parts stores. Make sure to use the correct amp rating for your brake lights.

Faulty Bulbs

If the fuse is intact, the next thing to check is the brake light bulbs themselves. Over time, bulbs can burn out and need to be replaced. This is a straightforward fix that you can do yourself.

Follow these simple steps to replace a brake light bulb:

• Open the trunk or liftgate to access the brake light assembly.
• Remove the screws or clips holding the assembly in place.
• Gently pull out the assembly to expose the bulbs.
• Twist the bulb socket counterclockwise to remove the old bulb.
• Insert a new bulb into the socket and twist it clockwise to secure it.
• Reinstall the brake light assembly and test the lights to ensure they are working.

Remember, it’s always a good idea to check both brake light bulbs, even if only one appears to be out. This can save you time and prevent future issues.

In conclusion, while having your brake lights not working can be frustrating, the fixes are often simple. By checking the fuse and replacing any faulty bulbs, you can get your 2002 Jeep Grand Cherokee back on the road safely. Have you ever had a similar issue with your vehicle?
