Pontiac LeMans Brake Light Switch Guide for 1983-1987 Models
If you own a 1983-1987 Pontiac LeMans, you likely have a Canadian model that shares its parts with the Chevrolet Celebrity.
- The 1983-1987 Pontiac LeMans was not sold in the US; you must search for parts for a Chevrolet Celebrity of the same year.
- New aftermarket switches are readily available from brands like Standard Motor Products, ACDelco, and Duralast.
- Before ordering, verify if your vehicle has cruise control, as this may require a different switch.
- If the switch replacement doesn't fix the issue, the turn signal (multi-function) switch is the next most likely cause.
The 1983-1987 Pontiac LeMans: A Parts-Finding Puzzle
If you're searching for a brake light switch for a 1983-1987 Pontiac LeMans in the United States, you've likely run into a problem: parts catalogs show a gap for these years. That's because the Pontiac LeMans was not sold in the U.S. market between 1982 and 1987. The mid-size LeMans was discontinued in 1981, and the name was reused on a completely different subcompact car starting in 1988.
However, a version of the Pontiac LeMans was sold in Canada during this period. This vehicle was a twin to the front-wheel-drive, A-platform Chevrolet Celebrity. Therefore, to find the correct brake light switch, you must search for a part that fits the Chevrolet Celebrity from the same model year.
Symptoms of a Failing Brake Light Switch
A bad brake light switch can cause several issues, some of which are serious safety concerns. Here are the most common signs of failure:
- Brake Lights Don't Work: The most obvious and dangerous symptom is when your brake lights fail to illuminate when you press the pedal.
- Brake Lights Stay On: The switch can also fail in the 'on' position, leaving your brake lights constantly lit. This can drain your battery and confuse other drivers.
- Intermittent Brake Lights: The lights may flicker or only work when you press the pedal in a specific way, indicating a worn-out internal connection.
- Cruise Control Won't Deactivate: If the switch fails, it may not send the signal to turn off the cruise control when you brake, which is a significant safety risk.
Pro Tip: Check the Turn Signal Switch
On many GM vehicles from this era, the power for the brake lights runs through the turn signal (multi-function) switch in the steering column. If your turn signals work but your brake lights do not, the problem could be the turn signal switch itself, not the brake light switch. This is a common point of failure.
Choosing the Right Aftermarket Switch
Since you'll be shopping for a Chevrolet Celebrity part, you will find that new aftermarket switches are both available and affordable. These parts were used on millions of GM vehicles, so supply is not an issue. Look for switches from these reputable brands:
- Standard Motor Products (SMP): A trusted aftermarket manufacturer known for producing reliable, OEM-quality electrical components.
- ACDelco: As GM's original parts division, ACDelco offers both OEM and quality aftermarket replacement parts that are a direct fit.
- Duralast: A popular and readily available brand that offers a dependable replacement part.
Important: When ordering, you must specify whether your car has cruise control, as the switches can be different.
| Part Type | Estimated Cost |
