Key Takeaways
  • Your Regency has two separate flashers: one for turn signals and one for hazards; identify which one has failed before buying a replacement.
  • The most difficult part of the replacement is finding the old flasher under the driver's side dash; listen for the clicking sound to locate it.
  • Before replacing a flasher, check for burnt-out bulbs, as this can cause the signals to flash rapidly or not work correctly.
  • An aftermarket flasher from a brand like Standard Ignition is a reliable and affordable solution for this repair.
The hazard warning flasher, also known as a turn signal relay, is a small electronic part that makes your turn signals and hazard lights blink. When you use your turn signal lever or press the hazard button, this relay interrupts the power to the light bulbs, creating the flashing effect. Your 1997-1998 Oldsmobile Regency has two separate flasher units: one for the turn signals and another for the four-way hazard lights. This means if your turn signals fail, your hazards might still work, and vice-versa, pointing you to which specific flasher has failed.

Is Your Regency's Flasher Failing?

A faulty flasher relay is a common issue on many GM vehicles of this era. The signs are usually straightforward. You might notice that your turn signals light up but don't flash, or they don't work at all. Sometimes, they may flash at an irregular rate before failing completely. Because the hazard and turn signal functions use separate flashers on your Regency, you can often diagnose the problem easily. If the turn signals work but the hazards don't, the hazard flasher is likely the culprit.

Check Your Bulbs First!

If your signals are flashing much faster than normal (a condition called "hyperflash"), it's usually a sign of a burnt-out turn signal bulb, not a bad flasher relay. The change in electrical resistance from the bad bulb causes the flasher to blink rapidly. Check and replace any bad bulbs before replacing the flasher.

Locating the Flasher Relays on Your Regency

Finding the flashers is often the hardest part of the job. They are located under the driver's side dashboard. According to service information for the similar Oldsmobile 88, the hazard flasher is to the right of the steering column support, while the turn signal flasher is on the left side of the support, sometimes attached to the firewall. Another source specifies the turn signal flasher is below the left side of the instrument panel and the hazard flasher is under the steering column support.

Pro Tip: The easiest way to find the correct flasher is to use your ears. Turn on the ignition and activate the turn signal or hazard lights (whichever one is still working). Listen for the clicking sound under the dash and follow it to the source. The flasher you feel clicking is the one you need to replace.

Choosing the Right Aftermarket Flasher

For a vehicle like the 1997-1998 Regency, a new aftermarket flasher is a reliable and cost-effective choice. OEM parts are no longer in production, so what you find are often new-old-stock or aftermarket parts from OEM suppliers like AC Delco.

Standard Ignition is a widely available and trusted aftermarket brand. Their components are made in ISO-certified facilities, ensuring a certain level of quality control. Owner reviews are generally positive, citing good performance for the price. Given that this is a simple relay, a Standard Ignition flasher is a dependable choice that should restore function without the high cost of a dealer part.

Part Type Estimated Cost Notes
New Aftermarket (e.g., Standard Ignition) $10.43 - $30.57 The most common and practical option. Price varies by retailer and specific model (e.g., heavy-duty).
New OEM / AC Delco $17 - $40 AC Delco is a GM original parts brand and offers a direct-fit replacement.
Shop Labor $50 - $100 Most shops will charge a minimum fee, typically for 30 minutes of labor, to locate and replace the part.

Frequently Asked Questions (FAQ)

Why did only my turn signals stop working but my hazards are fine?

Your 1997-1998 Regency uses two separate flasher relays—one for turn signals and one for hazards. This is why one can fail while the other continues to work perfectly. This separation makes it easier to identify which relay needs replacing.

Is it difficult to replace the hazard flasher myself?

No, the replacement itself is very easy. The part simply unplugs from its socket and the new one plugs in. The only difficulty is reaching the relay, which is tucked under the dashboard. It is considered a very feasible DIY job for any skill level.

Are there any recalls for this problem on my Regency?

No specific recalls or Technical Service Bulletins (TSBs) were found for the flasher relay on the 1997-1998 Oldsmobile Regency. While other GM models had recalls for similar issues around that time, they did not apply to this specific vehicle and part.

What's the difference between a thermal and electronic flasher?

Older cars used thermal flashers that use a heating and cooling metal strip to create the flash. Newer electronic or electro-mechanical flashers, like many modern replacements, use a circuit board. Electronic flashers are generally more durable and have a more consistent flash rate. For a stock replacement with incandescent bulbs, either type will work, but an electronic unit from a brand like Standard Ignition is a good upgrade.
