A Guide to the 1983-1988 Dodge Charger Brake Light Switch
Diagnosing and replacing the brake light switch in your classic L-Body Charger.
- A bad brake light switch is a critical safety issue that should be fixed immediately.
- Symptoms are clear: brake lights don't work, stay on, or the cruise control acts up.
- For this vintage of Charger, a quality aftermarket switch from a brand like Standard Ignition is a reliable and available option.
- Replacement is easy for a DIYer, with the main challenge being access under the dashboard.
Is Your Brake Light Switch Failing?
A faulty brake light switch on your Charger can be a safety hazard. The symptoms are usually straightforward and should be addressed quickly. Since this is a simple mechanical switch, the problems are almost always electrical in nature.
Key Symptoms of a Bad Switch:
- Brake Lights Don't Work: This is the most obvious and dangerous symptom. If you've checked the bulbs and fuses and they are good, the switch is the next most likely culprit.
- Brake Lights Stay On: A switch that is stuck in the 'on' position will keep your brake lights illuminated constantly, even when the car is off. This can drain your battery overnight. This can be caused by an internal failure or a missing plastic stopper on the pedal assembly.
- Intermittent Brake Lights: The lights may flicker or only work when you press the pedal extra hard. This suggests the internal contacts of the switch are worn out.
- Cruise Control Won't Deactivate: If your Charger has cruise control, a bad brake light switch may prevent it from disengaging when you press the brake pedal.
Safety First
Driving without functional brake lights is illegal and extremely dangerous. If you confirm your brake lights are not working, do not drive the vehicle until it is repaired.
Choosing the Right Aftermarket Switch
For a classic vehicle like the 1983-1988 Charger, finding original Mopar parts can be difficult. The OEM part may be discontinued. Luckily, the brake light switch is a simple component, and a quality aftermarket replacement is a reliable and cost-effective choice. Standard Ignition is a well-known brand that produces replacement switches for this vehicle.
For a simple part like this, there isn't a significant difference in quality tiers between the available aftermarket options. The key is to ensure you are buying from a reputable manufacturer like Standard Ignition rather than a no-name brand. The reliability comes from proper installation and adjustment.
Pro Tip: Check Your Connections
Before replacing the switch, inspect the wiring connector. On a 35+ year old car, connectors can become brittle or corroded. Sometimes, simply cleaning the contacts or ensuring a snug fit can solve the problem.

Frequently Asked Questions
Is this a difficult part to replace myself?
No, this is a very DIY-friendly job. The switch is located above the brake pedal and is usually held in by a clip or threaded into a bracket. The most difficult part is working in the tight space under the dashboard. You typically just need to disconnect the electrical connector, remove the old switch, and install the new one.
My new switch didn't fix the problem. What now?
If a new switch doesn't solve your brake light issue, check the basics again: the fuse and the bulbs. If those are good, the problem could be in the wiring itself or, in some Mopar vehicles, a fault in the turn signal switch, as the brake light circuit can pass through it.
Do I need to adjust the new switch?
Yes, adjustment is key. The switch has a plunger that is depressed when the brake pedal is at rest. You need to adjust its position so the brake lights turn on immediately as you begin to press the pedal, but are fully off when your foot is off the brake. Improper adjustment can cause the lights to stay on or have a delayed reaction.
Are there any recalls for the brake light switch on my Charger?
Based on searches of the NHTSA database, there are no specific, widespread recalls for the brake light switch on the 1983-1988 Dodge Charger. Recalls for this component are more common on much newer vehicles.
