Key Takeaways
  • The primary symptom of failure is your reverse lights not working, which is a safety issue.
  • On this vehicle, the switch is located on the steering column and is combined with the neutral safety switch.
  • Standard Ignition is a reputable aftermarket brand for this replacement part.
  • Replacement is a manageable DIY task that may require a simple adjustment after installation.
The back up light switch on your 1983-1990 Oldsmobile Custom Cruiser is a simple but important part. Its job is to turn on your reverse lights when you shift the car into reverse. This lets other drivers know you are backing up and lights the way behind you. On these station wagons, which have a column shifter, the switch is also part of the neutral safety switch. This means it also prevents the car from starting unless it is in Park or Neutral. The switch is located on the steering column inside the car.

Is Your Back Up Light Switch Failing?

A bad back up light switch can cause more than just an inconvenience; it's a safety issue. The most common sign of failure is when your reverse lights don't turn on at all when you shift into reverse. You might also see them flicker or only work sometimes. Before blaming the switch, it's always a good idea to check the bulbs and the fuse first, as these are easier and cheaper to fix. If the bulbs and fuse are good, the switch is the next likely culprit. In some cases, the switch may just need an adjustment, which can be done by loosening its mounting screws and repositioning it on the steering column.

Choosing the Right Aftermarket Switch

For a vehicle like the 1983-1990 Custom Cruiser, finding original OEM parts can be difficult and expensive. Aftermarket parts are a reliable and affordable alternative. The main brand available for this specific part is Standard Ignition (also sold under Standard Motor Products or SMP). Standard Ignition is a well-known aftermarket manufacturer that produces parts that meet or exceed original specifications. Their switches use copper alloy conductors for good electrical performance and are tested for reliability. For a simple electrical component like a back up light switch on an older car, a quality aftermarket part from a reputable brand like Standard Ignition is a practical and cost-effective choice.

Frequently Asked Questions

Where is the back up light switch located on my Custom Cruiser?

On the 1983-1990 Oldsmobile Custom Cruiser with an automatic transmission and column shifter, the back up light switch is part of the neutral safety switch assembly. It is located inside the car, mounted on the upper part of the steering column, near the floorboard.

Can I replace the back up light switch myself?

Yes, this is a DIY-friendly job for someone with basic mechanical skills. The switch is located inside the car on the steering column and is typically held on by two small screws. After installing the new switch, it may need to be adjusted to ensure the reverse lights come on at the right time and the car starts only in Park or Neutral.

Are there any recalls for the back up light switch on this car?

No, there are no specific recalls issued by the National Highway Traffic Safety Administration (NHTSA) for the back up light switch on the 1983-1990 Oldsmobile Custom Cruiser.

What's the difference between a back up light switch and a neutral safety switch?

On many older cars with column shifters like your Custom Cruiser, these two functions are combined into one part. The "neutral safety switch" part of the component prevents the engine from starting in gear, while the "back up light switch" part activates the reverse lights. If either function fails, the entire switch assembly usually needs to be replaced.
