1983-1984 Chrysler E Class Headlight Switch Replacement Guide
Having trouble with flickering headlights in your Chrysler E Class? Here’s what you need to know before you replace the switch.
- Flickering headlights are the number one sign of a failing switch in your E Class, caused by an old internal circuit breaker.
- This is a critical safety repair; do not drive at night or in bad weather with a faulty headlight switch.
- A new aftermarket switch from a brand like Standard Ignition is the most reliable replacement, as a used part is just as old as the one that failed.
- Always inspect the wiring connector for melting or heat damage when replacing the switch.
Is Your Headlight Switch Failing? Common Symptoms
On an older vehicle like the E Class, the headlight switch has seen decades of use. The internal electrical contacts wear down, and the built-in circuit breaker can become weak. This leads to classic and often dangerous symptoms. Here’s what to watch for:
- Flickering or Intermittent Headlights: This is the most common sign. The headlights may cut out while driving, especially on bumpy roads, and then come back on. This is often caused by an aging internal circuit breaker that is tripping and resetting as it overheats.
- Headlights Go Out Completely: The switch may fail entirely, leaving you in the dark. Sometimes the lights will only work if you jiggle the knob or hold it in a certain position.
- Dashboard Lights Don't Work: If you can no longer adjust the brightness of your instrument panel, or if the lights don't come on at all, the rheostat part of the switch has likely failed. This is a separate function from the headlights, but it's housed in the same component.
- Smell of Burning Plastic: A hot, electrical smell from under the dashboard is a serious warning sign. The high electrical current for the headlights can cause the switch's plastic wiring connector to overheat and melt over time. If you smell this, pull over and inspect the issue immediately.
Critical Safety Warning
Flickering or non-functional headlights are a major safety hazard and can make your vehicle illegal to operate at night or in poor weather. Do not drive the vehicle if your headlights are unreliable.
Known Issues, Recalls, or TSBs
There are no specific recalls or Technical Service Bulletins (TSBs) from the National Highway Traffic Safety Administration (NHTSA) for the headlight switch on the 1983-1984 Chrysler E Class. Problems with this part are due to the age and normal wear of the component. The owner is responsible for the diagnosis and repair.
Choosing the Right Aftermarket Headlight Switch
Since your E Class is over 40 years old, finding a new original equipment (OEM) part from a Chrysler dealer is not possible. Your options are a used OEM part from a salvage yard or a new aftermarket part.
- Used OEM: A used part is not recommended. It will be just as old as the part that failed and is likely to have the same issues.
- New Aftermarket: This is the best choice for a reliable, long-lasting repair. New switches are made with modern materials and are readily available.
Two common aftermarket brands you will find are Standard Ignition (Standard Motor Products) and Rostra Powertrain.
- Standard Ignition (SMP): This is a well-known and generally trusted brand in the aftermarket for electrical components. It is often recommended by mechanics for older vehicles and is considered a reliable choice.
- Rostra Powertrain: While Rostra makes a wide variety of parts, some forum users have reported mixed experiences with the quality of their electrical components compared to other brands.
Pro Tip: When replacing the switch, ALWAYS inspect the wiring connector that plugs into it. Look for any signs of melting, browning, or brittle plastic. A damaged connector is common and must be replaced to prevent the new switch from failing prematurely.

Frequently Asked Questions
Can I replace the headlight switch myself?
Yes, this is a feasible DIY job for someone with basic tools. The process generally involves reaching under the dash, pressing a small button on the switch body to release the knob and shaft, unscrewing a retaining nut from the dashboard, and unplugging the electrical connector. The most difficult part is often working in the tight space under the dashboard.
Why do my dash lights and headlights flicker at the same time?
The headlight switch powers both the headlights and the dashboard illumination circuit. The flickering is caused by the single internal circuit breaker in the switch assembly failing and cycling power to all the components it controls.
Are the lights supposed to feel 'mushy' or soft?
No. A good switch should have a noticeable 'click' between each position. A mushy or vague feeling is a strong indication that the internal mechanism of the switch is worn out and failing.
My headlights work, but my dash lights are out. Is it the switch?
Most likely, yes. The part of the switch that controls the dash light brightness (the rheostat) can fail independently of the part that turns on the headlights. If you cannot adjust your dash lights or they won't come on at all, the headlight switch assembly needs to be replaced.
