- The main symptom of failure is your reverse lights not working.
- Verify the correct part for your year (1973-79 vs 1980-84) and transmission type (auto vs manual).
- Standard Motor Products (SMP) is a reputable aftermarket brand for this part.
- This is a DIY-friendly repair for most home mechanics, with the switch located either on the steering column or transmission.
Symptoms of a Failing Back-Up Light Switch
A bad back-up light switch usually fails in one of two ways. The most common symptom is that the reverse lights don't turn on at all when you shift into reverse. You might also notice they only work sometimes or flicker when you move the shifter. Less often, the switch can fail in the 'on' position, causing the reverse lights to stay on even when you're not in reverse. This can confuse other drivers and drain your battery.
Choosing the Right Aftermarket Switch
For a vehicle like the 1973-1984 Omega, finding a new original equipment (OEM) part from GM is nearly impossible. The good news is that the aftermarket provides reliable replacements. The primary brand available for this part is Standard Motor Products (SMP), which is a well-regarded manufacturer known for producing quality components that meet or exceed original specifications. Given the age of the vehicle, a new aftermarket switch from a trusted brand like Standard is a much better choice than a used part from a salvage yard, which could have the same age-related issues as your old one.
Two Generations, Different Parts
The Oldsmobile Omega was built on two different platforms during this period: a rear-wheel-drive (RWD) version from 1973-1979 and a front-wheel-drive (FWD) version from 1980-1984. Additionally, switches differ between automatic and manual transmissions. It is critical to order the correct switch for your specific year, engine, and transmission type. Always verify the part fitment before purchasing.
Typical Replacement Costs
Replacing the back-up light switch is an affordable repair. The part itself is not expensive, and labor is minimal for a professional mechanic.
| Item | Estimated Cost |
|---|---|
| New Aftermarket Switch | $26 - $41 |
| Shop Labor | $60 - $120 |
| Total Estimated Cost | $86 - $161 |
Pro Tip: Before replacing the switch, always check the basics first. Make sure the bulbs aren't burned out and that the fuse for the circuit is good. Sometimes the fix is simpler than you think.
Frequently Asked Questions
Where is the back-up light switch located on my Omega?
The location depends on your transmission. For most automatic transmission models with a column shifter, the switch is mounted on the steering column under the dashboard. For manual transmission cars, the switch is usually screwed into the side of the transmission housing.
Is this a difficult part to replace myself?
For many DIY mechanics, this is a very manageable job. If the switch is on the steering column, it's usually held by two small screws and is accessible from under the dash. If it's on the transmission, you will need to safely raise the vehicle with jack stands to gain access. The difficulty is low, typically taking less than an hour.
My reverse lights flicker. Is the switch bad?
Flickering lights when you move the shifter are a classic sign of a worn or misaligned switch. Often, the internal contacts are worn out. On column-mounted switches, it's sometimes possible to slightly adjust its position to get a better connection, but replacement is usually the best long-term solution.
Are there any recalls for the back-up light switch on the Oldsmobile Omega?
No, searches of the National Highway Traffic Safety Administration (NHTSA) database show no recalls or specific safety campaigns for the back-up light switch on the 1973-1984 Oldsmobile Omega.
