What causes a brake light to keep blowing?
Somewhere your wiring or one of the bulbs on the brake light circuit probably has a dead short to the ground, which is the frame of the car. Don’t forget any add-on trailer harness. A likely cause is where something heavy has laid upon the wire, pinched it and worn through over time with vibration.
What should I do if my brake light is not working?
Replacing a socket is as simple as snipping the old wires and splicing in the new unit, which is typically an inexpensive part to purchase. If you keep these tips in mind, most brake light problems will be easy to diagnose and fix on your own.
Why does my brake light fuse keep blowing out?
If so, the fuse is functional, and the problem most likely is a used-up brake light bulb. If, however, the test light illuminates when the connection is only pressed against one side of the fuse, the fuse is faulty. If the test light fails to light at all, regardless of where it’s connected to the fuse, you definitely need to replace the fuse.
Can a brake light switch be replaced at the same time?
Replacing the switch is not a big job, and it’s also straightforward for your mechanic to test brake light problems like this one. If all three brake lights are out at the same time, it’s unlikely that the trio of bulbs died simultaneously.
How much does a new brake light bulb cost?
It is always a minimal cost for replacing the brake light bulb. A bulb costs from $5 to $10 and the charging process costs $20, so the maximum price will be around $30. How much does it cost to rewire brake lights?
Why does my brake light only work on one side?
Since the problem is only on one side, you can rule out the fuse and other parts of the circuit that are shared by both bulbs. I would look closely at the connector for the nonfunctional bulb, as it may be damaged or corroded. If the bulb looks OK, you’ll want to test for power and ground at the bulb.
What to do when your brake light has no power?
This portion of the guide is to help you test for power when one, both lower or all three brake lights have no power. Test the Fuses: Use the owners manual or the lid of the fuse panel to find the brake light fuse. Then use a test light to check the fuses for the brake light and BCM fuses and replace if any are blown.
Why are the brake lights not working but the tail lights are?
Blown out light bulbs are the most common reason for why the brake lights not working but the tail lights are. Remove the screws from the bulb lens (which you can access through the trunk or see your vehicle repair manual to get the exact location). Push the bulbs and turn them counterclockwise to remove from the socket.
Replacing the switch is not a big job, and it’s also straightforward for your mechanic to test brake light problems like this one. If all three brake lights are out at the same time, it’s unlikely that the trio of bulbs died simultaneously.
