Is Your Headlight Switch Failing? Common Symptoms
A faulty headlight switch can cause confusing and dangerous problems. Because the 1987-1991 Pontiac Tempest is a twin to the Chevrolet Corsica, they share the same electrical parts and potential issues. Here’s what to look for:
- Headlights Don't Turn On: The most obvious sign is when your headlights won't turn on at all, even with good bulbs and fuses. 🎬 Check out this video if your headlights aren't turning on.
- Lights Flicker or Turn Off While Driving: The internal circuit breaker can wear out over time. When it does, it can cause the headlights to flash on and off or shut off completely, which is a major safety hazard.
- Parking Lights or Dash Lights Malfunction: Since the switch controls multiple lighting functions, you might notice that only the parking lights work, or that the dashboard lights won't dim.
- Switch Feels Hot: As the internal contacts corrode, electrical resistance increases, generating heat. A switch that is hot to the touch is a clear sign of failure.
Recall Notice for Sister Vehicle
While no recalls are listed specifically for the Pontiac Tempest, its sister vehicle, the 1987 Chevrolet Corsica, had a recall for the headlight switch (NHTSA Campaign ID: 86V164000). The recall noted that a part of the pushbutton could break, preventing the headlights from turning on. Given the shared platform, Tempest owners should be aware of this potential defect.
Choosing a New Aftermarket Headlight Switch
Finding a new original equipment (OEM) headlight switch from GM for a vehicle of this age is nearly impossible. The most practical solution is a new aftermarket part. For the 1987-1991 Tempest, the primary brand available is Standard Ignition (also known as Standard Motor Products or SMP).
Standard Ignition (SMP): Standard is a well-known and generally respected aftermarket manufacturer. They produce a wide range of electrical components, and their parts are often considered a reliable alternative when OEM parts are discontinued. For a component like a headlight switch, a new part from a reputable aftermarket brand like Standard is often a better choice than a used OEM part from a junkyard, which may have the same age-related wear as the one you are replacing.
| Part Type | Estimated Cost |
|---|---|
| New OEM | Not Generally Available |
| New Aftermarket (Standard Ignition) | $57.21 |
| Used OEM (Salvage Yard) | $20 - $45 |
| Shop Labor | $75 - $150 |
Pro Tip: Check the Connector
When replacing the switch, always inspect the wiring connector. A failing switch can overheat and damage the plastic connector or terminals. If the connector looks melted, brittle, or discolored, it should be replaced at the same time to ensure a solid connection and prevent future problems.
Frequently Asked Questions (FAQ)
Is it difficult to replace the headlight switch myself?

It typically involves removing the trim piece around the switch, unscrewing the old switch, disconnecting the electrical plug, and then reversing the process. Basic hand tools 🎬 Watch this step-by-step video on how to replace the switch. are all that's required.
Do I need to disconnect the battery to replace the switch?
Yes, absolutely. Any time you work on your vehicle's electrical system, you should disconnect the negative battery terminal to prevent short circuits and protect yourself from injury.
My headlights work, but my high beams don't. Is that the headlight switch?
It could be, but it's more likely an issue with the dimmer switch, which is often part of the turn signal lever on this vehicle. The main headlight switch sends power to the dimmer switch, which then directs it to either the low or high beam circuits.
Why did my new aftermarket switch fail quickly?
Early failure is often caused by an underlying issue. A common cause is a damaged wiring connector that doesn't make a secure connection, leading to overheating that damages the new switch. Always inspect the connector when replacing the switch.
