Key Takeaways
  • New aftermarket back-up light switches for the 1983 Pontiac LeMans are no longer available.
  • The LeMans was not sold in the US market from 1984-1987, complicating parts searches.
  • Your best option is to find a used OEM switch, likely by searching for a 1982-1986 Pontiac Bonneville part.
  • The back-up light switch is usually integrated with the neutral safety switch on the steering column.
The back-up light switch, also known as a reverse light switch, is a simple but important safety device. When you shift your Pontiac LeMans into reverse, this switch closes an electrical circuit. This action sends power to the reverse lamps, illuminating them to signal that your vehicle is about to move backward. This switch is often integrated with the neutral safety switch, which prevents the engine from starting unless the car is in Park or Neutral.

A Note on the 1983-1987 Pontiac LeMans

Finding parts for this specific year range is complicated by the history of the LeMans model in North America. The mid-size, rear-wheel-drive LeMans was discontinued in the U.S. market after the 1981 model year, though it continued in Canada through 1983. The nameplate was then dormant in the U.S. until it returned in 1988 on a completely different, front-wheel-drive subcompact car. This guide focuses on the 1983 model, as the LeMans was not sold in the U.S. from 1984 to 1987.

Aftermarket Availability: A Dead End

There are currently no new aftermarket back-up light switches being manufactured for the 1983 Pontiac LeMans. Searches across major auto parts retailers and specialty suppliers come up empty for this specific application. While some parts are listed for the later 1988-1993 LeMans, they are not compatible with the 1983 model. This lack of availability means that finding a direct, new replacement part is not possible.

The Challenge of Obsolete Parts

For vehicles of this age, especially for models with inconsistent production history, parts often become obsolete. Manufacturers stop producing them due to low demand. This forces owners to seek alternative solutions when a replacement is needed.

What Are Your Options?

Since new aftermarket and OEM parts are unavailable, you will need to explore other avenues:

  • Used OEM Parts: This is the most viable option. Searching auto salvage yards, online used parts marketplaces, or classic GM forums may yield a functional used switch. The 1983 LeMans was a GM G-body car, similar to the 1982-1986 Pontiac Bonneville. It is highly likely that the back-up light switch from a contemporary Bonneville or other G-body cars (like the Chevrolet Malibu, Oldsmobile Cutlass Supreme, or Buick Regal) from the same era could be interchangeable. Always compare the old part visually with the potential replacement.
  • Neutral Safety Switch Assembly: The back-up light switch is often part of the neutral safety switch assembly, which is typically mounted on the steering column. Broadening your search to include "neutral safety switch" for the 1983 Pontiac Bonneville or other GM G-body vehicles may provide a path forward.
  • Repair or Rebuild: In some cases, a faulty switch can be disassembled, cleaned, and repaired. The contacts inside can become corroded or worn. This requires some technical skill but can be a last resort if no replacement can be found.

Pro Tip: When searching for used parts, use the term "1983 Pontiac Bonneville" or "GM G-body neutral safety switch" instead of LeMans. This will significantly increase your chances of finding a compatible part.

Frequently Asked Questions

Why can't I find a new back-up light switch for my LeMans?

The 1983 Pontiac LeMans had a very short production run before the name was temporarily retired in the U.S. Due to the low number of vehicles and the age, aftermarket companies no longer manufacture this specific part as it is not profitable.

Is there a recall for this part?

There are no specific recalls listed with the National Highway Traffic Safety Administration (NHTSA) for the back-up light switch on the 1983 Pontiac LeMans.

Where is the back-up light switch located?

On most GM vehicles from this era with an automatic transmission and a column shifter, the back-up light switch is integrated into the neutral safety switch. This assembly is typically located at the base of the steering column inside the car.

Can I use a switch from a different car?

Yes, this is your most likely solution. The switch from a 1982-1986 Pontiac Bonneville is a very strong candidate for being a direct fit. Parts from other GM G-body cars of the same period may also work. Always compare the part you are buying to your original switch to ensure the wiring connectors and mounting points match.

Technical Specifications

The switch is typically integrated with the neutral safety switch assembly and mounted on the steering column. Cross-referencing with GM G-body vehicles from 1982-1986 is recommended.
