If you want your car to be performing at its peak, then car care is imperative. Taking care of your vehicle goes a long way into providing safety and prolonging your car's life cycle.
One of the essential auto parts you need to take care of is your car's brake lights. Brake light problems aren't usually complicated. There are common issues that brake light problems that cause problems for car owners.
So if you are experiencing brake light problems and asking questions like "Why Are My Brake Lights Not Working?" Then you are in the right place.
The AutoPartsZ team listed the common reasons for brake lights not working and how to fix brake lights. So without further delay, let's get into it.
Common Brake Light Problems And Its Fixes
So brake lights usually have a long shelf life, but they can kick up some problems. Here are four common brake light problems:
Burnt Out Light Bulbs
Burnt out bulbs are the most common problem you will face with your brake light. The lights are always on when you are hitting your brakes.
Brake lights stay on as long as you are hitting the brakes and that means burnt out bulbs are more of an inevitability, and there is no real way to prevent burnout. This is why more and more manufacturers use LED lights as an alternate option in newer models instead of filament bulbs.
If you have a bulb instead of an LED light, you will need to pop out the bulbs and replace them. Here is an easy way to do it:
How To Fix Burned Out Brake Light Bulbs?
One of the first things you need to do when fixing a burnt out brake light is to shut down your engine and gather all your tools together. After you have all the things in place, you can start the following process:
- Find out what type of bulb you need for the replacement. Choosing the wrong bulbs will help you avoid electrical issues that come with using faulty bulbs. You can look to your owner's manual for more information on the right bulb sizes and voltages for all the lights in your car.
- When you have the replacement bulb, apply some bulb di-electric grease in the end. You do it because it helps you prevent rust or corrosion, plus it makes it easier to remove the bulb next time around.
- Before you start working on the car itself, you need to disconnect the batteries because it can cause electrocution or electrical problems.
- The next step for you would be to determine the type of lens you have in your car. There are usually two different types to choose from. Your car either has stationary lens assemblies or removable lens assemblies. The owner's manual of your car has more information on which one you need. Here is how you replace bulbs in both assembly types:
- With a stationary lens assembly, the bulbs and wiring are self-contained and mounted within the assembly, with the assembly being fixed into the car itself. For these assembly types, you need to hit the bulbs' disengaging mechanism once the lens cover is removed. After that, you can easily remove the faulty bulb and replace it with a new one.
- For removable assembly lenses, you can remove the entire fixture from your car. When taking out the whole assembly, you will find a wiring harness that connects to the brake light bulb, the backup bulb, and any other bulbs within the fixture. Be very careful when removing the assembly because you wouldn't want to damage the wiring. To remove the assembly, you can just hit the disengaging mechanism, and it will come out of your car. Then you can simply remove the bad bulb and reinstall the entire fixture.
Bad Break Light Switch
If you see that all three bake lights are out, then the odds are that your brake light switch is damaged or dirty.
Three lights don't usually go out together, and that's why you should check the brake light switch if this happens. The fix is pretty simple, and you don't have to wait for replacing the brake light switch.
For more information, you can check out this video or talk to your mechanic. The repair shop will easily be able to fix the problem.
So your lights aren't turning on, and you checked the switch, and it's all good then what's the problem? Well, most probably, the fuse for the brake circuit is blown.
Now you can find the fuse box under the hood or on the kick panel inside the passenger compartment.
There should be a diagram drawn on the box cover that will let you know which one is the brake fuse, or if you don't find it on the cover, then you will find it in your owner's manual. Here is how you can test and replace your brake fuse:
- Use a fuse puller, a small plastic tool to remove the fuse from the box.
- Once you find the brake fuse check it visually by holding it up to the light or use an in-block fuse tester to make sure it's functional. If the small filament is continuous from one side to the other, then the filament is melted, it means that something overheated the circuit.
- Make sure you use a multi-meter to check for continuity across the two terminals.
- Use the fuse puller to insert a new fuse of the proper amperage rating in the slot. Make sure you use the fuse that has the right amperage. You will find the amperage information in your owner's manual, and by putting in the new fuse, you are done with the replacement.
So if everything is right in the brake light assembly and system, then the odds are the light socket has a problem.
When checking the socket, check for a dirty or corroded socket and check the wiring for wear and tear because these are the problems stopping the connection from being made. Replacing the lousy socket is very easy. The part is inexpensive, and you can simply snip the old wires and splice in the new unit to have it replaced.
So there you have it. These are some of the most common brake light problems you will see when driving your car.
