1968-1970 Pontiac Executive Headlight Switch: A Comprehensive Guide
Flickering lights or a dark dashboard in your classic Pontiac Executive could mean it's time for a new headlight switch.
- Flickering headlights are a classic symptom of a failing switch, caused by the internal circuit breaker.
- Before ordering, check if your original switch has 7 or 8 terminals to ensure you buy the correct part.
- Standard Ignition is a reputable aftermarket brand known for quality, while 'Replacement' is a budget-friendly option.
- If a new switch doesn't fix dead headlights, check the floor-mounted high-beam dimmer switch next.
Signs of a Failing Headlight Switch
When the headlight switch in your Pontiac Executive starts to fail, the signs are usually hard to miss. Because the switch controls multiple lighting functions, you might notice a few different problems. Being able to spot them early can save you from being stuck in the dark.
Common Failure Symptoms
- Flickering Headlights: This is a classic sign. The internal circuit breaker may be old and weak, or corrosion on the contacts could be creating excess heat, causing the breaker to trip and reset continuously. This is both distracting and dangerous at night.
- Headlights or Parking Lights Don't Turn On: The switch may fail completely, leaving you with no headlights or parking lights at all. You might find that one setting works (like parking lights) but the other (headlights) does not.
- Dash Lights Not Working or Dimming: The rotating part of the switch, called a rheostat, can wear out. This will cause your instrument panel lights to stop working or prevent you from adjusting their brightness.
- Switch Feels Hot: An old switch with internal corrosion can build up resistance, generating heat. If the switch knob or the dash around it feels warm to the touch, it's a clear warning sign of impending failure.
Choosing the Right Aftermarket Headlight Switch
Since your Pontiac Executive is a classic, finding a brand-new Original Equipment (OEM) part from GM is highly unlikely unless you locate a pricey New Old Stock (NOS) part. For most owners, a new aftermarket switch is the best and most available option. The two main tiers you'll encounter are established brands and value-oriented generic brands.
Brand Tiers
- Standard Ignition (Standard Motor Products): This is a well-known and respected aftermarket manufacturer. Their parts are generally considered to be reliable, quality replacements that meet or exceed original specifications. Forum users and mechanics often trust SMP for electrical components like switches. Choosing this brand is a solid bet for long-term reliability.
- Replacement Brand: This is a generic name for parts that are designed to be a direct fit at a lower cost. While they are made to function like the original, the quality can sometimes be inconsistent compared to a name brand. For a critical safety part like a headlight switch, it's often worth spending a little more for the peace of mind a brand like Standard Ignition provides.
Aftermarket Headlight Switch Cost for 1968-1970 Pontiac Executive
The cost for a new aftermarket headlight switch is very reasonable. The primary difference in price is based on the brand.
| Brand Tier | Estimated Price |
|---|---|
| Replacement (Value) | $27.00 - $40.00 |
| Standard Ignition (Name Brand) | $40.00 - $60.00 |
Frequently Asked Questions
Can I replace the headlight switch myself?
Yes, this is a job that a DIY mechanic with basic tools can handle. The main challenge is the tight space under the dashboard. The process involves disconnecting the battery, reaching behind the switch to press a small release button, pulling the knob and shaft out, unscrewing the retaining nut, and unplugging the wiring harness.
Will a new switch fix my flickering dash lights?
Most likely, yes. The dimmer function for the dash lights is part of the headlight switch assembly. If your dash lights flicker, don't work, or won't dim, a new switch is the correct repair.
Are all 1968-1970 Pontiac Executive headlight switches the same?
No. While they look similar, there can be differences in the number of electrical terminals on the back. Many GM cars from this era used the same switch, but you must verify that the terminal count on the replacement part matches your original switch to ensure proper function.
My headlights don't work, but the switch is new. What else could it be?
On many classic GM cars, power for the headlights runs from the main switch to a floor-mounted dimmer switch for the high beams. These foot-operated switches are a very common failure point and can cause the headlights to stop working entirely. If a new headlight switch doesn't solve the problem, the dimmer switch is the next logical part to inspect.
