GMC Safari Back Up Light Switch Guide (1985-1990)
Fix your reverse lights for good by choosing the right back up light switch for your first-generation Safari van.
- On automatic models, the switch is part of the neutral safety switch on the steering column; on manuals, it's on the transmission.
- Always check the bulbs and fuses first before assuming the switch is bad.
- For automatic models, the switch can sometimes be adjusted before it needs to be replaced.
- ACDelco is the OEM quality choice, while Standard Ignition offers a reliable aftermarket alternative.
Is Your Back Up Light Switch Failing?
A bad back up light switch has a few clear signs. Since these first-generation Safari vans are getting older, this switch can wear out from use or the internal contacts can fail.
Common Symptoms
- Reverse Lights Don't Turn On: This is the most obvious symptom. When you shift into reverse, the lights stay off.
- Intermittent Reverse Lights: The lights may flicker or only work when you wiggle the shifter. This often points to a worn or misadjusted switch.
- Blown Fuses: In some cases, a shorted switch can cause the fuse that protects the circuit to blow. On some GM vehicles, this fuse may also be linked to the turn signals.
Pro Tip: Check the Easy Stuff First
Before you buy a new switch, take a moment to rule out other simple problems. First, check the reverse light bulbs to make sure they haven't burned out. Second, check the fuse for the backup lamps in your fuse panel. If the bulbs and fuse are good, the switch is the most likely problem.
Choosing the Right Aftermarket Switch for Your Safari
For a 1985-1990 GMC Safari, you have a few good aftermarket options. Since an OEM part from GM can be expensive or hard to find, a quality aftermarket replacement is usually the best choice.
Brand Quality Tiers
Tier 1: ACDelco
ACDelco is GM's official parts brand, and their products are considered to be original equipment (OE) quality. If you want a part that fits and performs exactly like the one your van came with from the factory, ACDelco is your best bet. It's the top choice for a guaranteed fit and long-term reliability.
Tier 2: Standard Ignition (SMP)
Standard Motor Products is a highly respected aftermarket manufacturer known for quality electrical components. For many professional mechanics, Standard is a trusted alternative to OEM parts. A Standard Ignition switch offers a great balance of high quality and a more affordable price point compared to ACDelco.
Tier 3: Replacement Brand
"Replacement" is a generic term for value-oriented brands. These switches are the most budget-friendly and will get your reverse lights working again. While they meet basic functional requirements, they may not have the same durability or precise finish as the higher-tiered brands. They are a good option if your primary concern is cost.
Important: Automatic vs. Manual Transmission
The back up light switch for an automatic transmission is different from the one for a manual transmission. The switch for the automatic is located on the steering column, while the manual transmission switch is on the side of the transmission case. Make sure you order the correct part for your specific vehicle configuration.

Frequently Asked Questions
Where is the back up light switch located on my Safari?
For 1985-1990 models with an automatic transmission, the switch is part of the neutral safety switch assembly located on the lower part of the steering column, inside the cabin. For manual transmission models, it is a separate switch screwed into the side of the transmission housing, accessible from under the vehicle.
Is the back up light switch the same as the neutral safety switch?
On automatic transmission models, yes. The functions of the neutral safety switch (which prevents the engine from starting in gear) and the back up light switch are combined into one part.
Can a bad back up light switch be adjusted?
Sometimes, yes. On automatic models, the switch on the steering column can sometimes be slightly rotated to correct its alignment with the gear selector. If your lights work intermittently or come on in the wrong gear, an adjustment might fix it. However, if the switch has failed internally, it must be replaced.
How difficult is it to replace the back up light switch?
For most DIY mechanics, this is a relatively easy job. On automatic models, it's accessible from inside the driver's footwell and typically takes less than an hour. On manual transmission models, you will need to safely raise the vehicle to access the switch on the transmission, which can be more difficult.
