Is Your Grand Am's Back Up Light Switch Failing?
A failing back up light switch is a safety issue and can get you a traffic ticket. The most obvious sign of a problem is when your reverse lights don't turn on. Before you blame the switch, always check for simpler problems first. Make sure the light bulbs aren't burned out and check the 'TURN LPS' or similar fuse in the fuse panel. Sometimes, a bad ground wire in the trunk can also cause lighting problems.
Key Symptoms of a Bad Switch
- Reverse lights do not turn on: This is the most common symptom. You shift into reverse, but the lights stay off.
- Reverse lights stay on: The switch might be stuck in the 'on' position, keeping the lights on even when you're not in reverse.
- Lights flicker when shifting: If you can make the lights flash by wiggling the gear shifter, it often points to a worn-out or poorly adjusted switch.
- Car won't start (Automatics Only): Since the switch is part of the neutral safety switch, a complete failure can prevent the car from starting because it doesn't recognize that it's in Park or Neutral.
Important Note for Automatic Transmissions
On automatic Grand Ams, the back up light switch is integrated into the Neutral Safety Switch. When searching for this part, you will see it listed under both names. They are the same component for this vehicle.
Choosing the Right Aftermarket Switch
When your original switch fails, you have a choice between an OEM part from GM and an aftermarket part. For a simple electronic switch like this, a quality aftermarket part can offer the same performance for less money.
- OEM (GM Genuine Parts / ACDelco): These are the exact parts your car was built with. They guarantee a perfect fit and function but come at a higher price.
- Aftermarket (Facet and others): Brands like Facet produce parts that are designed to be equivalent to OEM quality. Facet is an established Italian company that makes a wide range of automotive electronics. Aftermarket parts are a cost-effective option. When choosing one, look for a good warranty and positive user reviews if available.
Pro Tip: This is a straightforward replacement job. An experienced DIYer can save on labor costs, which could be more than the cost of the part itself. The switch is located on the transmission and is accessible from under the car.

Frequently Asked Questions
Where is the back up light switch located on a Grand Am?
For both automatic and manual transmission models, the switch is mounted on the transmission itself. You will need to safely raise the vehicle and look for a small sensor with a wiring connector, usually on the top or side of the transmission housing.
Can I replace the back up light switch myself?
Yes, this is a DIY-friendly repair for most home mechanics. The process involves disconnecting the battery, raising the car safely, unplugging the electrical connector, unscrewing the old switch, and installing the new one. It typically takes about an hour.
Are there any recalls for the Grand Am back up light switch?
No, there are no specific recalls or technical service bulletins (TSBs) from the NHTSA for the back up light switch or neutral safety switch on the 1997-2004 Pontiac Grand Am. There were major recalls for the ignition switch and multifunction switch, but these are different parts.
My reverse lights still don't work after replacing the switch. What now?
If a new switch doesn't solve the problem, you may have an issue elsewhere in the circuit. First, re-check the bulbs and the fuse. Next, inspect the wiring leading to the switch and from the switch to the tail lights for any breaks or corrosion. A bad ground wire in the trunk is another common cause of light failure on these cars.
