How to Fix Dodge Charger Brake Light Fail

By Nick Marchenko, PhD

Brake lights are a critical component of your Dodge Charger, ensuring safety on the road. If you're facing issues with non-functioning brake lights, this guide will walk you through a series of checks and fixes, consolidating advice from experienced Charger enthusiasts.

Step 1: Initial Check

• Inspect fuses related to the brake lights. For a Dodge Charger, these are usually fuses #8 in the front and #19 in the rear.
• First, rule out the obvious - check if your Charger's brake light bulbs are functioning. Remember, the bulbs should illuminate brighter when braking.

If one bulb from your Dodge Charger's brake lights is burned out, it simply needs to be replaced. Make sure you choose a bulb that is the right wattage and the right size. You can find that information here:

• 2017 Dodge Charger Light Bulbs;
• 2016 Dodge Charger Light Bulbs;
• 2015 Dodge Charger Light Bulbs;
• 2014 Dodge Charger Light Bulbs;
• 2013 Dodge Charger Light Bulbs;
• 2012 Dodge Charger Light Bulbs;
• 2011 Dodge Charger Light Bulbs;
• 2010 Dodge Charger Light Bulbs;
• 2009 Dodge Charger Light Bulbs;
• 2008 Dodge Charger Light Bulbs;
• 2007 Dodge Charger Light Bulbs;
• 2006 Dodge Charger Light Bulbs;

Step 2: Brake Pedal Switch

• If bulbs and fuses are fine, your next checkpoint is the brake pedal switch. Despite being a new switch, it's wise to test it. Use a multimeter to check for continuity when the brake pedal is pressed.

Step 3: Wiring and Connectors

• Inspect the wiring, particularly in areas prone to wear and tear. A common problem area is the rubber boot in the trunk hinge, where wires may get pinched or damaged.
• Check the trunk wiring harness and connectors. Ensure they are intact and have not been compromised due to constant trunk usage.

Step 4: Power Distribution and Relays

• Some Dodge Charger models have a 'stop lamp inhibit' relay in the rear power distribution center. If present, inspect and test this relay. A malfunction here could disable brake lights.
• Investigate the wiring harness running from the trunk's fuse to the brake switch. Look for any signs of damage or disconnection.

Step 5: Alternative Power Source (Temporary Solution)

If you discover a power supply issue to the brake switch, a temporary solution is to create a jumper wire from another power source. However, ensure this is a stopgap fix until proper repairs are made.

Step 6: Body Control Module (BCM) Check

For later models, issues might stem from the BCM, which controls exterior lighting. Using an OBD2/CAN scanner, check for any diagnostic codes that could indicate a BCM-related issue.
