Key Takeaways
  • Failure is common and presents as flickering lights, total light failure, or a burning smell.
  • Always check the fuse first before replacing the switch.
  • The replacement is an easy DIY job, but be careful with brittle dashboard plastic.
  • Standard Motor Products (SMP) is a highly regarded aftermarket brand for this part.
The headlight switch in your 1986-1993 Chevrolet Caprice is the main control for your exterior lights. It's more than just an on/off button. This switch, usually a knob on your dashboard, lets you turn on your parking lights and headlights. It also typically includes a function to dim the lights on your instrument panel. On these older GM vehicles, the switch is a common failure point because the internal metal contacts can wear out or overheat over time.

Is Your Headlight Switch Failing?

When the headlight switch on your 1986-1993 Caprice starts to go bad, the signs are usually pretty clear. You might be driving at night and suddenly find yourself in the dark, or your lights might just refuse to turn on in the first place. Because this is a critical safety part, you should replace it as soon as you notice a problem.

Common Symptoms of a Bad Headlight Switch:

🎬 Watch this video to help diagnose a failing headlight switch.
  • Headlights won't turn on: This is the most obvious and serious symptom. You might pull the switch and get nothing.
  • Lights work sometimes: The headlights or parking lights might flicker, or they might work one day and not the next. This can be caused by worn internal contacts.
  • Delay in lights coming on: You might pull the switch and have to wait several seconds before the headlights actually illuminate.
  • Burning plastic smell: A distinct smell of burning plastic or electronics coming from the dashboard area near the switch is a major red flag. This indicates the switch is overheating and could be a fire risk.
  • Inability to switch between high and low beams: While sometimes related to the dimmer switch on the steering column, a faulty main headlight switch can also affect high beam function.

A Note on Recalls

While there were no specific headlight switch recalls found for the 1986-1993 Caprice, GM did issue a recall in 1986 for other models like the Celebrity for a faulty headlight switch that could cause the lights to flicker or go out suddenly. This shows that similar switches from that era were known to have issues.

Choosing the Right Aftermarket Switch

For a vehicle like the '86-'93 Caprice, finding a brand-new OEM (Original Equipment Manufacturer) part from GM is highly unlikely. The good news is that the aftermarket provides several reliable options. The key is to choose a brand known for quality electrical components.

  • Standard Motor Products (SMP): Often considered a top-tier aftermarket brand, SMP parts are known for meeting or exceeding original specifications. They are a trusted choice for electrical parts and a solid option for your Caprice. Many professional mechanics use SMP.
  • Rostra Powertrain: Rostra is another established aftermarket manufacturer. While they produce a wide range of parts, including electrical components, owner reviews are more focused on their lighting systems like DRLs rather than specific replacement switches.

Given the options, Standard Motor Products (SMP) is a widely recommended and reliable choice for this specific part.

Typical Replacement Costs

Replacing the headlight switch on your Caprice is not an expensive job, whether you do it yourself or take it to a shop. The part itself is affordable.

Part Type Estimated Cost
New Aftermarket Headlight Switch $27 - $63
Shop Labor $75 - $150
Total Estimated Cost (Shop) $102 - $213

Frequently Asked Questions

Is it hard to replace the headlight switch myself?

No, this is a relatively easy DIY job for most people. It typically involves removing the dashboard bezel (the plastic trim around your gauges), unscrewing the old switch, unplugging its electrical connector, and then installing the new one. You'll likely need basic tools like a screwdriver. 🎬 Follow this step-by-step guide to replace your dashboard switch. Be gentle, as the old plastic on the dashboard can be brittle.

My high beams don't work. Is that the main headlight switch?

It could be, but it's more likely to be the dimmer switch. 🎬 See how to replace the high beam switch on your Caprice. On these Caprice models, the dimmer switch is a separate part located on the steering column, activated by the turn signal lever. If your headlights turn on but you can't switch between low and high beams, the dimmer switch is the first part to check.

Are all the switches from 1986 to 1993 the same?

No. There is a split between the 1986-1990 and 1991-1993 model years. The dashboard design changed, and so did the switch. Always confirm the part fits your exact year before ordering.

Could a fuse be the problem instead of the switch?

Yes, and it's always the first thing you should check. A blown fuse is a simple and cheap fix. If the fuse is good but the lights still don't work or act erratically, the switch is the next likely culprit.
