Dodge Colt Headlight Switch Guide: 1984-1992 Replacement
Everything you need to know about diagnosing and replacing the headlight switch in your 1984-1992 Dodge Colt.
- A failing headlight switch is a critical safety issue and should be addressed immediately.
- Always inspect the wiring connector for melting or damage when replacing the switch.
- A new aftermarket switch from a reputable brand like Standard Ignition is the most reliable option, as new OEM parts are unavailable.
- Replacement is a feasible DIY task for those comfortable working under the dashboard.
Symptoms of a Failing Headlight Switch
A headlight switch handles a lot of electrical current, and after 30+ years, failure is common. The internal contacts can wear out, or the plastic housing can become brittle. In some older vehicles, a common issue is the wiring connector itself melting from heat, which can cause similar symptoms. Look for these signs:
- Intermittent Headlights: Your headlights or taillights flicker, or cut out entirely while driving. You might need to jiggle the switch to get them to work.
- Total Failure: The headlights, parking lights, or dash lights do not turn on at all.
- Melted Connector: You may notice a burning plastic smell. Upon inspection, the plastic connector plugged into the back of the switch may be melted or discolored. This is a serious fire hazard.
- Dash Lights Inoperative: The switch's dimmer function for the instrument panel may fail, leaving you with no dash illumination.
Check the Connector First
Before ordering a new switch, inspect the wiring harness connector that plugs into it. If it shows signs of melting, scorching, or corrosion, it must be replaced along with the switch to ensure a lasting repair.
Choosing the Right Aftermarket Headlight Switch
For a vehicle like the 1984-1992 Dodge Colt, finding a new original equipment (OEM) headlight switch from a dealer is highly unlikely. Your primary options are a new aftermarket part or a used OEM part from a salvage yard.
- New Aftermarket (Recommended): Brands like Standard Motor Products (SMP) produce new replacement switches. These are engineered to fit and function like the original and are made with modern materials. Given the age of the vehicle, a new part is the most reliable choice. Forum users generally report positive experiences with Standard Ignition's quality for electrical components.
- Used OEM: While this is an option, you are buying a part that is just as old as the one that failed. It may have unseen wear and could fail sooner rather than later.
Headlight Switch Replacement Cost
The cost to replace the headlight switch depends on whether you do it yourself or hire a professional mechanic.
| Part Type | Estimated Cost |
|---|---|
| New Aftermarket (Standard Ignition) | $127.74 - $128.94 |
| Used OEM | $25 - $50 |
| Shop Labor | $100 - $150 |
Consider a Headlight Relay Kit
Many owners of older vehicles install a headlight relay harness. This kit pulls power directly from the battery to the headlights, using the headlight switch only as a low-power trigger. This takes the electrical load off the old wiring and switch, preventing future meltdowns and often resulting in brighter headlights.
Frequently Asked Questions (FAQ)
Can I replace the Dodge Colt headlight switch myself?
Yes, this is a manageable DIY job for most people with basic tools. The process typically involves removing the lower dash trim panel, reaching behind the switch to press a release button to remove the knob, unscrewing a retaining nut, and unplugging the electrical connector. The most difficult part is often working in the tight space under the dashboard.
Is Standard Ignition a good brand for this part?
Yes, Standard Motor Products (SMP) is a well-regarded aftermarket manufacturer with a long history. They are known for producing quality electrical components that often meet or exceed original specifications. For a critical safety part like a headlight switch, it is a reliable choice.
Why are my headlights flickering but the switch seems okay?
Flickering can be caused by a failing switch, but it can also be due to a poor electrical connection. Check for a loose or melted wiring connector at the back of the switch, a bad ground wire, or a problem with the headlight relay. On these older cars, the problem is often a heated and failed connection in the harness.
Are there any recalls for the 1984-1992 Dodge Colt headlight switch?
No, searches of the NHTSA database did not find any recalls specifically for the headlight switch on the 1984-1992 Dodge Colt. There was a recall for the 1992-1993 model, but it concerned a door latch switch, not the headlights.
