Dodge Charger Ignition Switch Guide: 1980-1984
If your Charger won't start or the key feels unreliable, your ignition switch could be the problem.
- Confirm the problem is the switch and not a simpler issue like a bad starter relay or corroded battery terminal.
- This part is shared with the Dodge Omni and Plymouth Horizon, so search for those models to find compatible aftermarket parts.
- Standard Motor Products (SMP) is a widely available and reliable aftermarket brand for this component.
- Consider replacing the inexpensive ignition lock cylinder at the same time for a complete repair.
Understanding Your 1980-1984 Charger
First, it's important to know that the Dodge Charger from 1980 to 1984 is based on Chrysler's L-body platform. This means it shares many parts, including the ignition switch, with the Dodge Omni and Plymouth Horizon. When searching for parts, looking for these models can give you more options.
Common Symptoms of a Failing Ignition Switch
A bad ignition switch can cause problems that seem related to other parts, like the battery or starter. Here are the most common signs that the switch itself is failing:
- Car Won't Start or Crank: You turn the key and nothing happens, or you only hear a single click. While this can be a battery issue, if the battery is good, the switch is a likely suspect.
- Engine Stalls After Starting: The car starts but immediately dies. This can happen if the switch provides power in the 'Start' position but fails in the 'Run' position.
- Intermittent Electrical Problems: Your radio, dashboard lights, or power windows may work one moment and not the next. This indicates a loose or worn connection inside the switch.
- Key is Hard to Turn or Feels Loose: While this can also be the ignition lock cylinder, a worn switch can cause binding or a lack of distinct 'clicks' between positions.
Pro Tip: Switch vs. Lock Cylinder
The ignition system has two main parts: the ignition lock cylinder (the mechanical part your key goes into) and the ignition switch (the electrical part it controls). They are sold separately. If your key is physically stuck or won't turn, the lock cylinder is likely the problem. If the key turns but you have electrical issues, the switch is the more probable cause.
Choosing the Right Aftermarket Ignition Switch
For a vehicle of this age, finding original OEM parts from a dealer is nearly impossible. Your options are New Old Stock (NOS), used parts from a salvage yard, or new aftermarket parts.
OEM (Used/NOS) vs. Aftermarket:
- New Aftermarket: This is the most practical choice. Brands like Standard Motor Products (SMP) offer direct-fit replacements that are affordable and widely available. They are designed to meet or exceed original specifications and are a reliable option for getting your Charger back on the road.
- Used OEM: A used part from a salvage yard is a low-cost option, but its remaining lifespan is unknown. Given the low price of a new aftermarket part, a used switch is generally not recommended.
Recommended Brands:
- Standard Motor Products (SMP): A well-regarded brand in the aftermarket industry, offering parts like the US103 or US94 that are compatible with the L-body Charger.
- OER (Original Equipment Reproduction): This brand specializes in reproduction parts for classic vehicles and offers a switch for this application.
| Part Type | Estimated Cost | Notes |
|---|---|---|
| New Aftermarket Switch | $20 - $40 | Readily available and affordable. The recommended option. |
| New Aftermarket Lock Cylinder | $15 - $30 | Consider replacing this with the switch if your key feels worn or loose. |
| Used OEM (Salvage) | $10 - $25 | Low cost, but no guarantee of lifespan. |
| Shop Labor | $100 - $200 | Typically 1-1.5 hours of labor. |
Frequently Asked Questions (FAQ)
Can I replace the ignition switch myself?
Yes, this is a feasible DIY job for someone with basic mechanical skills. It involves removing plastic covers around the steering column and a few screws holding the switch in place. No special tools are required, just a screwdriver and socket set.
Should I replace the ignition lock cylinder at the same time?
It's a good idea, especially since you will already have the steering column apart. The lock cylinder is also inexpensive, and replacing both at once ensures the entire ignition system is fresh, preventing future issues with a worn key or tumbler mechanism.
Could another part be causing my no-start problem?
Yes. On classic Mopar vehicles, starting issues can also be caused by a bad starter relay, a failed ballast resistor, or corroded connections at the firewall bulkhead. It's wise to check these simple items before replacing the ignition switch.
Are there any recalls for the ignition switch on my Charger?
No, there are no specific recalls or Technical Service Bulletins (TSBs) from the NHTSA for the ignition switch on the 1980-1984 Dodge Charger.
