Your Guide to the 1967-1984 Buick Riviera Back Up Light Switch
Solve your reverse light problems by understanding, diagnosing, and replacing the right switch for your classic Riviera.
- The switch location varies: it's either on the steering column (later models) or in the center console (earlier models).
- Always test bulbs, fuses, and wire grounds before buying a new switch.
- The back up light switch is often part of the neutral safety switch, which can also cause no-start issues.
- For this vehicle, a new aftermarket switch from a brand like Standard Ignition is the most reliable and cost-effective solution.
Is Your Back Up Light Switch Failing?
On a classic car like the 1967-1984 Buick Riviera, electrical gremlins are common. Before you assume the switch is bad, it's important to recognize the specific symptoms. A failing back up light switch often shows clear signs.
Common Failure Symptoms:
- No Reverse Lights: This is the most obvious sign. When you shift into reverse, the lights simply don't turn on.
- Flickering or Intermittent Lights: The lights may work sometimes but not others, or they might flicker. This can point to worn internal contacts in the switch.
- Lights Stay On: The switch can fail in the 'on' position, causing your reverse lights to stay lit even when you're not in reverse. This can confuse other drivers and will burn out your bulbs quickly.
First, Diagnose the Real Problem
Don't replace the switch just yet. On vehicles of this age, the problem is often simpler and cheaper than a bad switch. Follow these diagnostic steps first:
- Check the Bulbs: This is the most common cause. Check if the filaments are broken or burned out.
- Check the Fuse: A blown fuse will kill the power to the circuit. Look for the fuse labeled for turn signals or back up lights ("TURN B/U").
- Inspect Wiring and Grounds: This is a very common issue on older cars. Look for corroded bulb sockets, loose connectors, or a bad ground wire. Forum members frequently solve their lighting issues by cleaning electrical contact points and ensuring a solid chassis ground.
- Test the Switch: If the bulbs, fuse, and wiring are good, use a test light to check if power is going into and out of the switch when the car is in reverse. If power goes in but doesn't come out, you've found your culprit.
Choosing the Right Aftermarket Part: Standard Ignition
For a 1967-1984 Riviera, finding a New Old Stock (NOS) OEM switch is nearly impossible and often very expensive. A used switch is a gamble. The most practical choice is a new aftermarket part. Standard Ignition (a brand of Standard Motor Products) is a well-regarded option that produces OE-quality replacement parts. They are known for using quality materials like copper alloy conductors and for testing their switches to ensure performance. For a simple but important part like this, a reliable aftermarket brand provides peace of mind without the high cost of NOS parts.
Generation Differences & Installation
Where you find the switch depends on your Riviera's generation and shifter type. This is the most common mistake when ordering a new part.
- Column Shifter Models (Common on late '70s - '80s): The switch is typically a curved plastic component mounted to the bottom of the steering column, inside the car under the dashboard. It often just snaps into place. Sometimes, the problem is simply that the old switch has come loose from its mounting point.
- Floor/Console Shifter Models (Common on '60s - early '70s): The switch is usually located inside the center console, mounted to the shifter assembly. Accessing it requires removing parts of the console to get to the shifter mechanism.

Frequently Asked Questions
Can I drive with a broken back up light switch?
While the car will operate, driving without functional reverse lights is a safety hazard for pedestrians and other drivers. It may also be illegal in your area and could cause you to fail a safety inspection. It is recommended to fix it as soon as possible.
My car won't start. Could it be the back up light switch?
Yes. On many Riviera models, the back up light switch is integrated into the neutral safety switch. The neutral safety switch prevents the engine from starting unless the car is in Park or Neutral. If this combined switch fails, it can cause a no-start condition as well as non-working reverse lights.
Is replacing the switch a DIY job?
For a moderately skilled DIY mechanic, yes. The difficulty is usually low, but access can be tight, especially for switches located on the steering column under the dash. If your switch is in the center console, the job is more about carefully disassembling the console without breaking old plastic trim.
The new switch is installed, but the lights still don't work. What now?
First, check the switch's adjustment. It must be perfectly aligned with the shifter mechanism to engage correctly when you select reverse. If the alignment is correct, re-check your grounds and all wiring connections. Old wiring can be brittle, and a connection may have come loose during the repair.
Technical Specifications
OEM part numbers vary significantly by year, transmission, and shifter location. It is critical to use a catalog to match the aftermarket part to your specific vehicle year and model. The switch is often combined with the neutral safety switch and will have multiple electrical pins.
