- Symptoms like a burning smell or smoke from the dash are critical warnings of a melted switch and wiring connector, which is a known issue.
- The Standard Ignition aftermarket switch is a reliable and affordable replacement, as original Mopar parts are rare and expensive.
- DIY replacement is possible but requires removing the instrument panel cover to access the switch.
Diagnosing a Failing Headlight Switch in Your TC Maserati
Due to the age of the 1989 Chrysler TC Maserati, the headlight switch is a common point of failure. The internal contacts can wear out or corrode, leading to increased electrical resistance, which generates heat. This can cause a range of symptoms from minor annoyances to serious safety hazards.
Key Failure Symptoms:
- Flickering or Intermittent Headlights: Lights may cut in and out as you drive or when you jiggle the switch knob.
- Headlights or Parking Lights Won't Turn On: The switch may fail completely, leaving you without exterior lights.
- Dash Lights Not Working: You may lose illumination for your gauges, often requiring you to wiggle the switch to get them to work.
- Smoke or Burning Smell from the Dash: This is a serious sign that the switch is overheating and melting, which can damage the wiring connector. If you see smoke, stop driving the vehicle and disconnect the battery until the switch can be replaced.
Melted Wiring is a Known Issue
Many TC owners have discovered a partially melted wiring harness connector when replacing their headlight switch. This is caused by the old switch overheating due to high resistance. When you replace the switch, it is critical to inspect the connector for signs of melting, charring, or corrosion. A damaged connector will cause the new switch to fail prematurely and can be a fire hazard.
Choosing a Replacement Headlight Switch: OEM vs. Aftermarket
Finding a New Old Stock (NOS) Mopar headlight switch for a 1989 TC Maserati is increasingly difficult and can be expensive. While used OEM parts from salvage yards are an option, they carry risks, as you might be getting a part that is near the end of its own service life. For a reliable and accessible solution, a new aftermarket switch is often the best choice.
Standard Ignition (Standard Motor Products) is a well-regarded aftermarket brand that produces a replacement switch for this vehicle. They are known for making quality components that meet or exceed original specifications, making them a dependable option for keeping your classic on the road. The switch is also reportedly the same as those used in 1984-1989 Chrysler LeBarons and Dodge Daytonas, which improves availability.
Pro Tip: Check for Cross-Compatibility
Forum users have noted that the headlight switch for the TC Maserati is shared with more common Chrysler models from the same era, like the LeBaron and Daytona. This can make it easier to find a compatible aftermarket part if one is not listed specifically for the TC.

Frequently Asked Questions
Can I replace the headlight switch myself?
Yes, this is a feasible DIY job for someone with basic tools and patience. The main challenge is accessing the switch, which requires removing the instrument panel cover. The trickiest part is often removing the switch knob itself, which has a small release clip. After that, it's a matter of unbolting the old switch, unplugging it, and installing the new one.
Are there any recalls for the 1989 TC Maserati headlight switch?
No, searches of the National Highway Traffic Safety Administration (NHTSA) database did not show any recalls or investigations specifically related to the headlight switch for the 1989 Chrysler TC Maserati.
What causes the headlight switch to fail?
The primary cause of failure is age and use. Over decades of operation, the electrical contacts inside the switch wear down. This creates higher resistance, which generates heat. This heat can eventually cause the switch's internal components and the external plastic connector to melt, leading to a complete failure.
Is the Standard Ignition brand a good choice for my TC?
Yes, Standard Motor Products (SMP) is a reputable aftermarket manufacturer with a long history of producing reliable electrical components. For a classic vehicle where OEM parts are scarce, a new switch from Standard is a solid and trustworthy repair option.
