A Mechanic's Guide to the 1991-1999 Ford Taurus Brake Light Switch
Solve common issues like getting stuck in Park or failing brake lights with the right replacement switch.
- A faulty brake light switch is a primary cause for a 1991-1999 Taurus being stuck in Park.
- Symptoms include brake lights not working, staying on, or an inoperative cruise control system.
- Driving without working brake lights is extremely dangerous and illegal; this repair should not be delayed.
- Replacement is simple for a DIYer, located under the dash on the brake pedal arm.
Is Your Taurus Stuck in Park? It Could Be This Switch.
One of the most common complaints from owners of this generation of Ford Taurus is the shifter getting stuck in Park. Before suspecting a major transmission problem, the brake light switch should be the first part you check. This switch sends the signal that allows the shifter to move. If the switch fails, the car doesn't know you're pressing the brake and won't release the shifter as a safety precaution.
Symptoms of a Failing Brake Light Switch
A bad brake light switch can cause several problems, some of which are serious safety concerns. Look out for these signs:
- Brake lights don't work: The most dangerous symptom. The switch has failed in the 'off' position, making you invisible to drivers behind you when you slow down.
- Brake lights stay on: The switch is stuck in the 'on' position. This will confuse other drivers and can drain your battery overnight.
- Cannot shift out of Park: As mentioned, this is a classic symptom for the Taurus. The shift interlock isn't receiving the signal to release.
- Cruise control won't engage or cuts out: The system may think the brakes are being applied, preventing the cruise control from working correctly.
- ABS warning light comes on: In some cases, a faulty switch can send an incorrect signal to the anti-lock brake system computer, triggering a warning light.
Safety First: A Critical Part
Driving with malfunctioning brake lights is illegal and extremely dangerous. If you suspect your brake light switch has failed, especially if the lights are not illuminating at all, you should not drive the vehicle until it is repaired.
Choosing the Right Aftermarket Switch
For a part this critical to safety and vehicle function, quality matters. While there are many low-cost options available, some aftermarket switches are known to fail prematurely. Ford issued a recall for the brake light switch on the following generation (2000-2003 Taurus) due to a high failure rate, replacing it with a more robust design. This suggests that even the original factory parts had durability issues.
When choosing a replacement, consider a reputable aftermarket brand known for quality components. Brands like Standard Ignition (SMP) have a long history of producing reliable engine management and electrical parts. Opting for a well-regarded brand over a generic, unbranded part is a wise investment for long-term reliability.
| Part Type | Estimated Price Range |
|---|---|
| New Aftermarket (Rostra, Standard Ignition) | $16.32 - $20.45 |
| New OEM (Ford/Motorcraft) | $18.00 - $40.00 |
| Shop Labor | $50 - $100 |
Pro Tip: Check the Fuse First
Before you replace the switch, always check the brake light fuse in the interior fuse panel. A simple blown fuse can cause the same symptoms and is a much easier fix.
Frequently Asked Questions (FAQ)
Can I replace the brake light switch myself?
Yes, this is a DIY-friendly job for most home mechanics. The switch is located on the brake pedal support bracket under the dashboard. It's in an awkward spot, but replacement is straightforward. You typically just need to disconnect the electrical connector and remove a small retaining pin or clip. No special tools are usually required, though a pair of pliers can be helpful. The job can often be done in under 30 minutes.
How do I know if it's the switch or just burnt-out bulbs?
If only one of your three brake lights is out, the problem is a bulb. If all brake lights stop working at the same time, the switch (or a fuse) is the most likely culprit. Also, if you are experiencing other related issues like being stuck in Park or a non-working cruise control, the problem almost certainly points to the switch.
Why does the new switch look different from the old one?
Part designs are often updated over the years to improve reliability. Ford itself updated the switch for the next generation of Taurus due to a recall. As long as the new switch is specified for your 1991-1999 Taurus, it should fit and function correctly even if it doesn't look identical to the original part.
I heard about a Ford recall causing fires. Is this the same part?
No, that is a different part. There was a major recall on a separate switch called the cruise control deactivation switch, which could leak brake fluid and cause a fire, even with the car off. That switch is located on the brake master cylinder under the hood. The brake light switch discussed in this article is located inside the car on the brake pedal and does not carry the same fire risk.
