Ignition Switch Guide for the 1977-1988 Dodge Dart
Having trouble starting your Dart? The ignition switch could be the problem. Here’s what you need to know.
- The 1977-88 Dodge Dart in North America is likely a Mexican-market model based on the Dodge Aspen/Volare (F-body) or Diplomat (M-body).
- Symptoms of failure include stalling, no-start conditions, and flickering accessories.
- Always inspect the wiring connector for heat damage or melting when replacing the switch.
- Standard Motor Products (SMP) is a reputable aftermarket brand for this component.
Understanding Your 1977-1988 Dodge Dart
First, it's important to clarify which Dodge Dart this guide is for. In the United States, the Dodge Dart was produced until 1976. However, the Dart name continued in other markets. In Mexico, the car sold as the Dodge Dart from 1977 to 1988 was based on the Chrysler F-body platform, the same platform used for the U.S. market Dodge Aspen and Plymouth Volare. Later, from 1981-1982, the M-body Dodge Diplomat was also sold as a Dart in Mexico. This guide focuses on the ignition switch for these F-body and M-body platform vehicles, which are mechanically similar to their U.S. counterparts.
Common Symptoms of a Failing Ignition Switch
A bad ignition switch can cause a range of frustrating electrical problems. 🎬 Watch this video to identify common symptoms of a bad switch. Because it controls power to so many systems, a failure can be hard to diagnose. You might notice the car won't start, or it might stall unexpectedly while driving. Often, the connector on the switch can overheat, causing melted plastic and poor connections.
Warning Signs
- Car Won't Start: You turn the key and nothing happens—no crank, no dashboard lights.
- Stalling While Driving: The engine may suddenly shut off, which can be dangerous. This happens if the switch loses contact and cuts power to the ignition system.
- Intermittent Electrical Issues: Accessories like the radio or dashboard lights may flicker or stop working randomly.
- Key Feels Loose or Gets Stuck: While often related to the lock cylinder, difficulty turning the key can also be a sign of a failing internal switch mechanism.
- Car Dies When Using Accessories: In some cases, turning on the headlights or another high-draw accessory can cause enough of a voltage drop across a faulty switch to stall the engine.
Choosing the Right Aftermarket Ignition Switch
For vehicles of this age, OEM parts from a dealer are generally not available. The aftermarket is your primary source. Fortunately, brands like Standard Motor Products (SMP) provide reliable replacements.
Brand Quality: Standard Ignition
Standard Motor Products (SMP) is a well-regarded aftermarket manufacturer that has been around since 1919. They are known for producing quality electrical components that often meet or exceed original specifications. For many Mopar applications, SMP is a trusted choice among mechanics and enthusiasts. Their parts are generally considered a solid, reliable option compared to lesser-known or budget brands. The Standard Ignition switches for this vehicle range are designed with copper alloy conductors for good conductivity and are tested for both mechanical and electrical performance.
Pro Tip: Check the Connector
When replacing your ignition switch, always inspect the wiring harness connector. These old Mopar connectors are known to overheat and melt, especially at the main power feed wire. 🎬 See how to identify and repair burned Molex connector terminals. If the plastic is melted or the terminals are burnt, the connector should be repaired or replaced to prevent the new switch from failing prematurely.
Cost to Replace an Ignition Switch
The cost to replace an ignition switch is relatively low, especially if you do the work yourself. The main cost is the part itself, with labor being an additional factor if you take it to a shop.
| Category | Estimated Cost |
|---|---|
| New Aftermarket Part (Standard Ignition) | $44.21 - $68.82 |
| Estimated Shop Labor | $100 - $200 |
| Total Estimated Cost (Shop Repair) | $144 - $269 |
Frequently Asked Questions (FAQ)
Is it hard to replace the ignition switch myself?
For most experienced DIY mechanics, this is a manageable job. The switch is located on the steering column, so you will need to work under the dashboard. It can be in a tight space. The difficulty is generally considered low to moderate, and it can typically be done in about an hour.
Were there any recalls for the ignition switch on these cars?
Searches on the National Highway Traffic Safety Administration (NHTSA) database for the 1977-1988 Dodge Aspen, Plymouth Volare, and Dodge Diplomat did not show any specific recalls for the ignition switch itself. While Chrysler had ignition switch recalls for other models in different years, this specific platform does not appear to have a relevant recall.
What's the difference between the ignition switch and the ignition lock cylinder?
The ignition lock cylinder is the mechanical part you put your key into. The ignition switch is the electrical component that the lock cylinder operates. If your key is hard to turn or gets stuck, the problem is likely the lock cylinder. 🎬 Learn how to fix a key that randomly won't turn. If you have electrical problems like a no-start or stalling, the ignition switch is the more likely culprit.
Do I need any special tools for the job?
Basic hand tools like a socket set and screwdrivers are usually all that's required. No highly specialized tools are typically needed for this replacement. Having a test light or multimeter is also very helpful for confirming the old switch is bad and the new one is working correctly.
