A Practical Guide to the 1989-1997 Ford Probe Brake Light Switch
Solving common brake light and cruise control issues starts with this simple but critical part.
- Verify your Probe's generation (1st: 1989-92, 2nd: 1993-97) before ordering, as they use different switches.
- Symptoms include non-working brake lights, lights stuck on, cruise control failure, and being unable to shift from Park.
- This is a simple, DIY-friendly repair that usually takes less than 30 minutes.
- Do not confuse this switch with the separate, fire-risk cruise control deactivation switch on the master cylinder, which should also be inspected.
Is Your Ford Probe Brake Light Switch Failing?
A faulty brake light switch can cause confusing and dangerous problems. Because it's tied to multiple systems, the symptoms aren't always obvious. Knowing what to look for can save you time and a potential traffic ticket.
Common Symptoms of a Bad Switch:
- Brake Lights Don't Work: The most serious symptom. A helper can confirm if your lights are out when you press the pedal.
- Brake Lights Stay On: The switch can get stuck in the 'on' position, which can drain your battery and confuse other drivers.
- Cruise Control Issues: Your cruise control may not turn on, or it might shut off by itself. This happens because the faulty switch is sending an incorrect signal.
- Can't Shift Out of Park: On automatic models, a bad switch won't tell the shift interlock to release the gear selector.
Safety First: The Cruise Control Deactivation Switch Recall
It's important to know there was a major Ford recall for a different switch: the cruise control deactivation switch, located on the brake master cylinder. This switch could leak brake fluid and cause a fire. While the Probe was not explicitly named in most recall lists, it shares technology from that era. Check under your hood on the master cylinder for a switch with a wiring harness. If you see any signs of fluid leakage around it, address it immediately. This is NOT the same as the brake light switch on the pedal, but it is a critical safety check for any owner of a 90s Ford-era vehicle.
Choosing the Right Aftermarket Brake Light Switch
For a vehicle like the 1989-1997 Probe, original Ford (OEM) parts can be hard to find or discontinued. Luckily, the aftermarket offers several good options that meet or exceed original quality for this simple part.
Know Your Probe's Generation!
The most common mistake when ordering is getting the wrong part for your year. The Ford Probe has two distinct generations that use different switches.
- First Generation (1989-1992): Uses OEM part number E8GY-13480-B.
- Second Generation (1993-1997): Uses OEM part number F32Z-13480-A.
Always confirm your vehicle's year before adding a part to your cart. Since the Probe was a joint venture with Mazda, these parts are often shared with the Mazda MX-6 and 626 of the same years.
Brand Tiers for Your Consideration
When choosing from available brands, here’s a general quality breakdown based on industry reputation:
- Tier 1 (Premium Aftermarket): Standard Ignition (SMP) is a well-respected brand known for producing reliable electronic components and sensors that often rival OEM quality. For a critical safety part, this is a dependable choice.
- Tier 2 (Standard Aftermarket): Brands like Facet and Rostra Powertrain are established aftermarket manufacturers that provide a cost-effective balance of quality and price. They are a solid choice for a standard repair.
For this part, an OEM switch is not mandatory. A quality aftermarket switch from a reputable brand like Standard Ignition will perform reliably and is more readily available.
Pro Tip: Check the Bumper Pad
The brake light switch has a small plastic plunger that is pressed by a small pad or bumper on the brake pedal arm. Over decades, this plastic bumper can become brittle and crumble. If it's missing, the switch won't be activated correctly, mimicking the symptoms of a bad switch. Always check this pad when replacing the switch—it's a very inexpensive part that can save you a headache.

Frequently Asked Questions
Is it difficult to replace the brake light switch myself?
No, this is a great DIY task for beginners. The switch is located above the brake pedal. It typically involves unplugging the wire connector and removing a small clip or pin. The job usually takes less than 30 minutes and requires only basic hand tools.
My brake lights are stuck on. Is that the switch?
Most likely, yes. The switch has failed in the closed or 'on' position. This will keep the brake light circuit active, draining your battery. Replacing the switch should solve the problem.
I replaced the switch and my cruise control still doesn't work. What now?
First, double-check the switch adjustment to ensure it's working correctly. Second, remember the separate cruise control deactivation switch on the master cylinder that was part of a major recall. This switch is a very common failure point for Ford cruise control systems of this era and should be your next item to inspect.
How do I know if I have a 1st or 2nd Gen Probe?
The first generation has a more angular body style and was sold from 1989 to 1992. The second generation has a more rounded, smoother body style and was sold from 1993 to 1997. They use different parts, so ordering for the correct year range is essential.
