Ford Aerostar Hazard and Turn Signal Flasher Guide (1992-1997)
Having trouble with your turn signals or hazard lights? Here’s what every 1992-1997 Aerostar owner needs to know.
- The hazard and turn signal flasher is a single part on the 1992-1997 Aerostar.
- Failure results in turn signals/hazards not working, working intermittently, or staying on without flashing.
- The flasher is a square 3-prong relay located under the driver's side dash, to the left of the fuse box.
- Replacement is a simple DIY task that involves unplugging the old relay and plugging in the new one.
Is Your Aerostar's Flasher Failing?
When the hazard and turn signal flasher goes bad, the symptoms are usually obvious. Because this single part controls two systems, you might notice issues with one or both. It's a common point of failure in aging electrical systems.
Key Symptoms of a Bad Flasher:
- No Turn Signals or Hazards: The most common sign is when both the turn signals and the hazard lights stop working completely. You won't hear the typical clicking sound from under the dash.
- Lights Stuck On: Your turn signal or hazard light indicators may stay lit without flashing.
- Intermittent Operation: The signals might work sometimes and fail at other times, which can be frustrating and dangerous.
- Only One System Works: You might find that your turn signals work, but the hazard lights don't, or vice-versa. This can still point to a problem within the flasher relay.
Pro Tip: Check Your Bulbs First
If your signals are blinking much faster than normal (a condition called "hyper-flash"), the problem is almost always a burnt-out bulb, not the flasher relay. The change in blinking speed is designed to alert you to a bad bulb. Check all four corner signal bulbs before replacing the flasher.
Choosing the Right Aftermarket Flasher
For a vehicle like the 1992-1997 Aerostar, the original Motorcraft flasher (Part No. F2UZ-13350-AA or SF-602) may be hard to find or expensive. Aftermarket parts offer a reliable and affordable solution.
Standard Ignition (Standard Motor Products): This is a well-regarded aftermarket brand known for producing parts that meet or exceed original specifications. Their components are manufactured in certified facilities and are designed to match the original part's fit and function, making them a dependable choice for your Aerostar.
Known Issues & Recalls
There are no specific recalls from the National Highway Traffic Safety Administration (NHTSA) for the hazard warning flasher on the 1992-1997 Ford Aerostar. However, some owners have reported confusion about the part's location, often mistaking a round slot in the fuse box for the flasher's position. The correct part is a square, 3-prong relay located separately from the main fuse panel.
DIY Replacement: An Easy Fix
Replacing the flasher is one of the easiest repairs you can do on your Aerostar. It's a simple plug-and-play part.
- Locate the Flasher: On the 1992-1997 Aerostar, the flasher is located under the driver's side dashboard, behind the instrument panel and to the left of the fuse box. You will need to remove the plastic cover under the steering column to see it. 🎬 Watch this walkthrough to replace the relay without removing the dash.
- Identify the Part: Look for a small, black, square-shaped relay with three prongs. You can turn on your hazard lights (if they work intermittently) and feel for the relay that is clicking.
- Swap the Part: Turn the vehicle off. Firmly pull the old flasher out of its socket. You may need to wiggle it gently.
- Install the New Flasher: Align the prongs on your new Standard Ignition flasher with the socket and push it firmly into place.
- Test: Turn the key to the 'On' position and test your left and right turn signals and your hazard lights to confirm the repair.

Frequently Asked Questions
Is the turn signal flasher the same as the hazard flasher on an Aerostar?
Yes. For the 1992-1997 model years, a single electronic flasher relay controls both the turn signals and the hazard warning lights.
Where is the flasher located on a 1996 Ford Aerostar?
It is located behind the dashboard on the driver's side, to the left of the main interior fuse panel. It is not the round flasher socket located in the fuse panel itself, which confuses many owners.
Can I drive my Aerostar without working turn signals?
It is not safe and is illegal in most places to drive without functioning turn signals. While the vehicle will still run, you will not be able to signal your intentions to other drivers, creating a serious safety risk. You are legally required to use hand signals if your lights are broken.
Why do my signals blink fast but all the bulbs are good?
While a fast blink usually means a bad bulb, if you have replaced all bulbs and the problem persists, it could be a sign of a poor electrical ground or a compatibility issue if you have installed LED bulbs without an electronic flasher designed for them. However, for standard halogen bulbs, a bad ground connection is the next most likely culprit.
