Is Your Impala's Back Up Light Switch Failing?
If you're having trouble with your reverse lights or starting your 1981-1995 Impala, the Neutral Safety Switch (which includes the back up light switch) is a likely culprit. Due to its location and function, this switch endures constant use every time you start your car or shift gears. Over decades, the internal electrical contacts can wear out, corrode, or the plastic housing can become brittle and break, leading to failure.
Key Failure Symptoms
- No Reverse Lights: The most common symptom is the complete failure of the back up lights to turn on when in reverse.
- Reverse Lights Stuck On: The switch can fail in a 'closed' position, causing the reverse lights to stay on even when you're not in reverse.
- No-Start Condition: The car may not crank when in Park or Neutral because the switch isn't sending the 'safe to start' signal to the ignition system.
- Starts in Wrong Gear: A severely failed switch might allow the engine to crank while in Reverse or Drive, which is a major safety hazard.
Choosing the Right Aftermarket Switch
For a vehicle of this vintage, finding a new original equipment (OEM) part from a dealership is nearly impossible. The aftermarket is the primary source for these switches. Fortunately, brands like Standard Ignition (also sold as Standard Motor Products or SMP) provide reliable, direct-fit replacements.
- Quality: Aftermarket brands like Standard Ignition are a trusted choice in the repair industry. They manufacture parts to meet or exceed original specifications, often using durable materials like high-quality plastics and copper conductors to ensure a long service life. For a straightforward part like this switch, a quality aftermarket unit is a practical and cost-effective solution.
- Availability: These switches are readily available from most auto parts suppliers. Given the shared platform with the Chevrolet Caprice, parts are generally easy to find.

Pro Tip: Before replacing the switch, always check the simple things first. Make sure the reverse light bulbs are good and that the "TURN B/U" fuse in the fuse panel is not blown. A test light can be used to confirm if power is reaching the switch, which can help avoid an unnecessary replacement.
Frequently Asked Questions (FAQ)
Where is the back up light switch located on my 1981-1995 Impala?
For models with an automatic transmission and a column shifter, the switch is located inside the car. You can find it mounted to the base of the steering column, up under the dashboard near the firewall. It's a crescent-shaped plastic component with a wiring harness connected to it.
Can I replace this switch myself?
Yes, this is a DIY-friendly job for most home mechanics. It typically requires removing the lower dash panel for access, disconnecting the battery, unplugging the electrical connector, and unbolting the old switch from the steering column. The most critical part of the installation is properly adjusting the new switch so that the reverse lights and neutral safety function work in the correct gear positions.
Are there any recalls for this part?
No, there are no active or historical recalls or common Technical Service Bulletins (TSBs) from GM specifically for the back up light switch on the 1981-1995 Chevrolet Impala. Failures are typically due to normal age and wear on the component.
My reverse lights flicker. Is that the switch?
Flickering or intermittent reverse lights are a strong indicator of a failing switch. The internal contacts wear out and can no longer maintain a solid connection. It could also be caused by a loose electrical connector at the switch or worn shifter linkage, but the switch itself is the most common cause.
