Dodge Caravan Headlight Switch Guide: 1987-1991
Everything you need to know about diagnosing and replacing the headlight switch in your first-generation Dodge Caravan.
- A failing headlight switch is a critical safety issue, with sudden headlight failure being the main symptom.
- This is a DIY-friendly repair; the main challenge is removing the knob and shaft by pressing a hidden release button.
- Always inspect the wiring connector for melting or damage; replace it with the switch if necessary to prevent repeat failure.
- Standard Ignition is a well-regarded aftermarket brand for this part; OEM parts are no longer available new.
Is Your Caravan's Headlight Switch Failing?
A bad headlight switch on these older Caravans isn't just an inconvenience; it's a major safety issue. The most common and dangerous symptom is the total loss of headlights while driving. You might find that the high beams only work when you physically hold the turn signal lever in the 'flash-to-pass' position. Before the switch fails completely, you might notice flickering headlights or dash lights. A mushy or soft feeling when pulling the knob, instead of a distinct click, is another strong indicator of an impending failure. In some cases, you may also lose your rear running lights, even if the brake lights still work.
Critical Failure Warning
The primary failure mode for the 1987-1991 Dodge Caravan headlight switch is sudden and complete headlight loss. This is often caused by the internal circuit breaker failing or the electrical connector melting from heat and age. If your headlights cut out, do not assume they will come back on. This is a critical safety failure requiring immediate attention.
Choosing the Right Aftermarket Headlight Switch
For a vehicle of this age, finding an original OEM switch from a dealer is highly unlikely. The market is served by aftermarket manufacturers, which offer a direct-fit replacement. The key is choosing a brand known for quality.
- Standard Ignition (Standard Motor Products): This is a widely available and generally well-respected brand for aftermarket electrical components. For decades, they have been a primary supplier of quality replacement parts for domestic vehicles. Many professional mechanics and experienced DIYers use their parts with confidence. When purchasing, be aware that SMP has different product tiers; their main line is generally considered high quality, while their budget "T-Series" line may have lower quality control.
- Rostra Powertrain: While Rostra is a known manufacturer of various automotive switches and electronics, they are more recognized for cruise control systems and transmission components. Finding specific reviews or feedback on their headlight switches for this particular Caravan model is difficult.

Frequently Asked Questions
Can I replace the headlight switch myself?
Yes, this is a job a DIYer with basic tools can handle. The process involves removing the instrument panel trim bezel around the switch, unscrewing the switch from the dashboard, and disconnecting the electrical plug. The most difficult part is often reaching the release button on the bottom of the switch to remove the knob and shaft.
My headlights went out. How do I know it's the switch?
While a failed switch is a prime suspect, the issue could also be a blown fusible link. A mechanic would test for power at the main red wire going into the switch connector. If there is 12-volt power there, but no power coming out to the headlight circuit when the switch is on, the switch itself has failed. If there is no power going into the switch, the problem is further up the line.
Are there any recalls on the 1987-1991 Caravan headlight switch?
No, there are no specific NHTSA recalls or Technical Service Bulletins (TSBs) for the headlight switch on the 1987-1991 Dodge Caravan. Later model years of the Caravan had recalls for headlight switch issues, but these do not apply to the first generation.
What's the difference between OEM and Aftermarket for this part?
For this vehicle, a new OEM (Original Equipment Manufacturer) part is essentially unavailable. Aftermarket parts from reputable brands like Standard Ignition are designed to be direct replacements that meet or exceed the original specifications. Given the age of the vehicle, a new aftermarket switch is often a better choice than a used OEM part from a junkyard, which would have the same age and potential for failure as the part you are replacing.
