1964-1973 Chevrolet Impala Back Up Light Switch: A Comprehensive Guide
Solve reverse light problems on your classic Impala by understanding how the back up light switch works and how to replace it.
- Identify your Impala's transmission (auto/manual) and shifter (column/floor) to buy the correct switch.
- Symptoms include no reverse lights, intermittent lights, or lights on in the wrong gear.
- Always check fuses, bulbs, and grounds before assuming the switch is bad.
- Aftermarket brands like Standard Ignition are the industry standard for reliable, stock-style replacements.
Symptoms of a Failing Back Up Light Switch
When the back up light switch fails, the symptoms are usually straightforward. The most common issue is that the reverse lights do not turn on at all when you shift into reverse. You might also notice them working only sometimes, which could point to a worn-out switch or a loose connection. In other cases, the lights might stay on even when you are not in reverse, or they could light up in the wrong gear, like Park or Neutral. This often means the switch is simply out of adjustment. Before replacing the switch, it's a good idea to check the bulbs, the fuse, and the wiring for any obvious problems like corrosion or bad grounds, as these can cause similar symptoms.
Diagnose First, Replace Second
Many reverse light issues on classic cars stem from bad grounds or corroded wires, not the switch itself. Always check the bulbs and test the circuit with a multimeter before buying a new part. A common test is to bypass the switch with a jumper wire; if the lights turn on, the switch is likely the problem.
Choosing the Right Aftermarket Switch
For a vehicle from the 1964-1973 model years, finding a new original equipment (OEM) part from GM is highly unlikely. The market for these components is served by quality aftermarket manufacturers who specialize in restoration parts.
- Standard Ignition (Standard Motor Products): This is a widely trusted brand for OEM-equivalent replacement parts. Their switches are designed to match the fit and function of the original factory part. For a stock restoration or a standard repair, Standard Ignition is a reliable choice.
- Mcleod: Known for performance drivetrain components, Mcleod offers switches that can be used for back up lights, often in conjunction with their manual transmission shifters. This brand is a good option if you are doing a manual transmission conversion or looking for a heavy-duty, universal-style switch.
The most critical factor is matching the switch to your Impala's specific configuration: transmission type (automatic or manual) and shifter location (column or floor console).
A Note on Adjustment
For switches mounted on the steering column, replacement often requires a final adjustment. This is done by slightly loosening the mounting screws and rotating the switch until the reverse lights activate precisely when the shifter is in the 'R' position and not in any other gear.

Frequently Asked Questions
Where is the back up light switch on my 1964-1973 Impala?
The location depends on your car's setup. For most automatic, column-shifted Impalas, it's part of the neutral safety switch located on the steering column under the dashboard. For cars with a floor shifter (manual or automatic), the switch is typically mounted on the shifter mechanism under the center console. Some manual transmission cars have the switch mounted directly on the side of the transmission case.
Can I replace the back up light switch myself?
Yes, this is a DIY-friendly task for most home mechanics. It usually involves disconnecting the battery, accessing the switch, unplugging the electrical connector, removing a couple of screws, and installing the new part. The main challenge can be reaching the switch, especially if it's high up on the steering column. Adjusting the new switch is a key step to ensure it works correctly.
What causes the back up light switch to fail?
Failure is typically due to age and wear. The internal contacts can wear out, or the plastic housing can become brittle and crack. Misadjustment can also cause it to function incorrectly. Since it's an electrical part, corrosion on the terminals or wiring can also interrupt the signal and make it seem like the switch has failed.
Are there any recalls for the Impala back up light switch?
No, there are no specific recalls or Technical Service Bulletins (TSBs) from the NHTSA for the back up light switch on the 1964-1973 Chevrolet Impala. Recalls for vehicles of this age are rare and typically focus on major safety systems.
Technical Specifications
Typically a two-terminal switch for manual transmissions or a multi-terminal switch combined with the neutral safety function for automatics. Wires are often light green and dark green.
