Brake lamps are one of the most important safety features that you can put on any Chevy Blazer or on any car. They will let others know that you are going to be a little less careful and that others should also be careful. If the brake light on your Chevy Blazer does not work, you are way more liable to get rear-ended than usual. It is very easy to find a problem with your brake lights; it simply requires checking a few things. This happens because the brake light switch on the car does not work properly.

How to Fix Chevy Blazer Brake Lights Not Working

Check the Fuse

If no light comes from the front brake pedal, we are just following the circuit from the fuse box to the pedal. At one point, there is no way that power can get to all the points on the circuit. You just have to figure out why that is. It is possible all the brake lights are burned out at the same time. You are just going to have to track down the power source. Just remember that the tail light will still work if the brake lights are totally dead. It could easily be that all the brake lights on the car all at the same time exploded.

If none of the brake lights on your car are turning on, you first need to replace the fuse. You may be able to pull the fuse and check to see if the circuit is working.

Even though it may seem like the fuse is okay, if you have a fuse of the same amperage, you should still swap it. It is better to test circuits by using a common household light to test for proper conductivity. Walmart or any part store will have it in stock, often for $10 or so.

Check the Brake Light Switch

Under the Blazer’s brake pedal is the switch for the brake lights. Even when the key is turned off, there should always be electricity going to it. At this time, a test light is absolutely necessary. This is demonstrated in detail in the video below.

It is much simpler to notice because he has removed the brake light switch from the car. This is not something you must do. There are two wires in all, one of which is always hot. The brake lights receive this power when you depress the brake pedal. The most likely point of failure is here.

It may seem like you are driving two vehicles with two different brake levers. There are two buttons that you can use to force the cruise control to stop working whenever you are pressing the brakes. You will need your owner’s manual to figure out which one is which. But, the power to the power switch for the car’s cruise controls will not come when the key is turned off, much as it comes when the brake light switch is turned off.
