Chevrolet Silverado 1500 Brake Light Bulb Fault: How To Diagnose And Fix

By Nick Marchenko, PhD

Hey Chevrolet Silverado 1500 enthusiasts! Ever found yourself in a pickle with brake lights that just won't cooperate? Well, buckle up, because I'm about to guide you through a DIY fix that could save you a trip to the mechanic and a hefty bill. We're focusing on the Chevrolet Silverado 1500 here, and while I won't specify the year, this guide generally applies to several models.

Fuse and Relay Check

First things first, let's talk about fuses and relays. These little guys are often the unsung heroes in electrical repairs. For your Silverado 1500, you're going to want to check a couple of fuse boxes. The first one is hiding on the driver's side. Just open the door, and you'll see a cover on the side of the dash. Pull that out, and voila – fuse box!

Now, here's a pro tip: always test your fuses and relays. Sometimes a fuse might look fine but is actually the root of all your problems. Don't trust your eyes alone; test them to be sure. You'll thank me later!

Not sure which fuses are responsible for the brake light in your Chevy Silverado 1500? Check out in the owner's manual:

• 2017 Chevroler Silverado 1500 Fuses;
• 2016 Chevroler Silverado 1500 Fuses;
• 2015 Chevroler Silverado 1500 Fuses;
• 2014 Chevroler Silverado 1500 Fuses;
• 2013 Chevroler Silverado 1500 Fuses;

Identify Key Fuses

In the world of brake lights, three fuses are your main suspects: numbers 5, 8, and 12. Locate these in your dashboard fuse box and give them a good check.

Under the Hood

Next, we're going under the hood. On the right side, there's another fuse box waiting for your detective skills. Here, you'll need to inspect two more fuses: numbers 1 and 49. These could be the culprits behind your brake light blues.

Checking the Brake Light Switch

If the fuses and relays are all singing the right tune but your brake lights still aren't playing ball, the issue might lie with the brake light switch. This little gadget can be tested to ensure it's working correctly. We've got a video on our channel that walks you through this process step-by-step.

Remember, folks, always have the right tools and parts for the job. If you need to buy anything, look for quality and quick shipping – your time and money are precious. With the right approach and a bit of patience, you can tackle this issue head-on and get your Chevrolet Silverado 1500's brake lights shining bright once again. Safe travels and happy fixing!
