1984-1989 Dodge Lancer Brake Light Switch Replacement and Diagnosis
Keep your classic Lancer safe and legal by understanding how to spot and fix a failing brake light switch.
- A bad brake light switch is a critical safety failure; do not drive if your brake lights are not working.
- Symptoms include brake lights not working, staying on, or cruise control failure.
- For this vehicle, a new aftermarket switch from a brand like Standard Ignition is the most reliable and available option.
- Replacement is an easy DIY job for most owners, typically taking less than 30 minutes.
Is Your Dodge Lancer's Brake Light Switch Failing?
A faulty brake light switch is a serious safety issue that can lead to a rear-end collision. Because the 1984-1989 Dodge Lancer is a classic vehicle, parts like this can fail from simple age and decades of use. Recognizing the symptoms early is key to staying safe on the road.
Common Failure Symptoms
- Brake Lights Don't Work: This is the most dangerous symptom. If the switch fails in the open position, your brake lights will not illuminate at all when you press the pedal.
- Brake Lights Stay On: A switch that fails in the closed or 'on' position will keep your brake lights constantly lit. This can confuse other drivers and will drain your vehicle's battery.
- Intermittent Brake Lights: If the internal contacts are worn, your brake lights might flicker or only work some of the time.
- Cruise Control Won't Engage: For Lancers with cruise control, a bad switch can prevent the system from turning on because it may incorrectly signal that the brakes are being applied.
Safety and Legality
Driving without functional brake lights is illegal and extremely unsafe. If you confirm your brake lights are not working, do not drive the vehicle until the switch is repaired.
Choosing the Right Aftermarket Switch for Your Lancer
For a vehicle from the 1980s, finding a new original equipment manufacturer (OEM) brake light switch from Chrysler is highly unlikely. The primary option for a new part is the aftermarket.
Standard Ignition is a well-known aftermarket brand that has been trusted by technicians for many years. For the 1984-1989 Lancer, this is often the only new brand available. Aftermarket parts from reputable brands like Standard are a reliable choice for replacing a worn-out original switch and are generally preferred over a used part from a junkyard, which would have an unknown history and lifespan.
Brake Light Switch Replacement Cost for 1984-1989 Dodge Lancer
The cost for this part may seem high compared to switches for more common vehicles. This is likely due to it being a low-production part for an older car.
| Part Type | Estimated Cost |
|---|---|
| New Aftermarket (Standard Ignition) | $85.89 |
| New OEM | N/A (Generally discontinued) |
| Used OEM | $15 - $40 (Salvage yard part, not recommended) |
| Shop Labor | $50 - $120 |
DIY Installation
Replacing the brake light switch on a Lancer is a straightforward job for a DIYer. It is typically located above the brake pedal and held in by a clip or threaded into a bracket. The process involves disconnecting the battery, unplugging the electrical connector, removing the old switch, and installing the new one. No special tools are usually required, and the job can often be done in under 30 minutes.
Frequently Asked Questions
Are there any recalls for the 1984-1989 Dodge Lancer brake light switch?
Searches of the National Highway Traffic Safety Administration (NHTSA) database show no open recalls or technical service bulletins (TSBs) specifically for the brake light switch on the 1984-1989 Dodge Lancer. Recalls for this part on much newer Dodge models exist, but they do not apply to this vehicle.
My brake lights don't work. Is it definitely the switch?
Not necessarily. Before replacing the switch, always check the simple things first: the brake light bulbs and the fuse for the brake light circuit. If both are good, the switch is the next most likely cause.
Why is this aftermarket switch so expensive?
While most brake light switches cost between $15 and $40, the higher price for this specific part reflects the realities of the classic car market. Tooling and production runs for parts for older, less common vehicles like the Lancer are smaller, leading to a higher cost per part.
Can I just use a switch from another Chrysler product of the same era?
Possibly, but it is not recommended. While many Chrysler K-platform cars shared parts, there can be subtle differences in the electrical connectors or plunger length. Using the exact part specified for your vehicle is the only way to guarantee proper fit and function.
