Chevrolet Nova Brake Light Switch Guide: 1985-1988 Models
Keep your brake lights working correctly by choosing the right replacement switch for your Nova.
- A faulty brake light switch is a critical safety issue; replace it immediately if your brake lights are not working.
- For this Toyota-built Nova, aftermarket brands like Beck Arnley or Standard Ignition are excellent, reliable choices.
- Replacement is a simple DIY task that takes less than 30 minutes and requires no special tools.
- Verify if your car has cruise control before ordering, as some switches are specific to that option.
Symptoms of a Failing Brake Light Switch
A bad brake light switch can cause several obvious and frustrating problems. Because this generation of Nova is a joint GM-Toyota vehicle, its electrical system is straightforward, making diagnosis easier. Here are the most common signs of failure:
- Brake Lights Don't Work: This is the most serious symptom. If the switch fails in the 'off' position, your brake lights will not illuminate when you press the pedal, creating a major safety hazard.
- Brake Lights Stay On: If the switch gets stuck in the 'on' position, your brake lights will remain lit even when your foot is off the pedal. This can drain your battery overnight and confuse other drivers.
- Cruise Control Won't Engage or Disengages Randomly: The cruise control system uses the brake light switch to know when to turn off. A faulty switch can prevent the cruise control from working at all.
Safety First
Driving without functional brake lights is illegal and extremely dangerous. If you suspect your brake lights are not working, inspect the switch and bulbs immediately and avoid driving until the issue is resolved.
Choosing the Right Aftermarket Brake Light Switch
For a 1985-1988 Nova, an original GM part can be hard to find and expensive. Aftermarket parts offer a reliable and affordable solution. Since your Nova was built by Toyota, brands that specialize in parts for Japanese vehicles are often an excellent choice. Here’s a look at the available brands:
- Top Tier Aftermarket (Recommended):
- Standard Ignition (SMP): A leading aftermarket manufacturer known for quality electrical components that meet or exceed original specifications. They are a trusted choice for reliability.
- Beck Arnley: This brand specializes in parts for foreign nameplate vehicles. They are well-regarded for their quality and sometimes even supply the same part as the original manufacturer in their own box. Given the Nova's Toyota roots, this is a strong option.
- Standard Aftermarket:
- Facet: An established brand that produces a wide range of automotive components. Reviews are generally positive, citing them as quality products and perfect replacements, making them a solid, budget-friendly choice.
- Rostra Powertrain: Rostra is a known manufacturer of automotive electronics, including for original equipment manufacturers. Their parts are engineered to be direct-fit replacements and are 100% tested for reliability.
| Part Type | Estimated Cost |
|---|---|
| New Aftermarket | $13.52 - $22.35 |
| New OEM (GM/Toyota) | $45 - $70 |
| Shop Labor | $40 - $80 |
Pro Tip: Check for Cruise Control
Some replacement switches are specific to models with or without cruise control. Although the core function is the same, the number of electrical terminals may differ. Always verify this detail before ordering to ensure you get the right part.
Installation Guide
Replacing the brake light switch on a 1985-1988 Nova is a simple job that most DIYers can complete in under 30 minutes with basic hand tools.
- Locate the Switch: The switch is mounted on a bracket just above the brake pedal arm. You will need to look up into the dashboard from the driver's side footwell.
- Disconnect the Wiring: Carefully unplug the electrical connector from the back of the switch.
- Remove the Old Switch: The switch is typically held in place by a retaining nut or by a simple twist-and-lock mechanism. Unscrew the nut or turn the switch counter-clockwise to remove it from the bracket.
- Install the New Switch: Installation is the reverse of removal. Screw in or twist the new switch into place and reconnect the electrical harness.
- Test for Function: Before driving, have a helper stand behind the car to confirm that the brake lights turn on when you press the pedal and turn off when you release it.
Frequently Asked Questions (FAQ)
Do I need a special tool to replace the brake light switch?
No, special tools are not required. You may need a small wrench or pliers to remove the retaining nut, but the job can often be done by hand.
My brake lights work, but my cruise control doesn't. Could it still be the switch?
Yes. Many brake light switches have separate internal contacts for the brake light circuit and the cruise control circuit. It's possible for one to fail while the other still works.
Are there any recalls for the brake light switch on my Nova?
No, there are no active recalls or common TSBs issued by the NHTSA for the brake light switch on the 1985-1988 Chevrolet Nova.
Why is my new switch a different color than the old one?
The color of the plastic housing can vary between manufacturers and does not affect the function of the part. As long as the connector shape and number of pins match, it will work correctly.
