Ford Taurus Brake Light Switch Guide: 2008-2019 Problems and Replacement
If your Taurus won't shift out of park or the brake lights are acting up, the brake light switch is the likely culprit.
- A bad brake light switch is a critical safety issue; replace it immediately if your brake lights are not working.
- Symptoms are not limited to lights; a faulty switch is a common cause for being stuck in park and for cruise control failure.
- Replacement is simple, inexpensive, and can be done by most DIYers in under 30 minutes.
- While no recalls exist for this part on 2008-2019 models, always check fuses before replacing the switch.
Is Your Ford Taurus Brake Light Switch Failing?
A faulty brake light switch can cause several confusing and dangerous problems in your 2008-2019 Ford Taurus. Because this small switch is tied into multiple vehicle systems, its failure can mimic other, more serious issues. Understanding the symptoms is key to a quick and correct diagnosis.
Top 5 Failure Symptoms
- Brake Lights Don't Work or Stay On: The most obvious sign is your brake lights not lighting up when you press the pedal, which is a major safety hazard. Conversely, the switch can fail in the 'on' position, leaving your brake lights permanently illuminated and draining your battery.
- Stuck in Park: Your Taurus has a safety feature called a shift interlock that prevents you from shifting out of 'Park' unless the brake pedal is pressed. If the switch is bad, the transmission control module never gets the signal, and your gear shifter will be stuck.
- Cruise Control Won't Engage: The brake light switch is designed to immediately cancel the cruise control when you tap the brakes. If the switch is faulty, it may constantly send a 'braking' signal, preventing you from setting the cruise control at all.
- Intermittent Electrical Issues: You might notice brake lights flickering when you go over bumps. On some models with push-button start, a bad switch can prevent the car from starting because it doesn't recognize that the brake pedal is depressed.
- ABS or Traction Control Warning Lights: On some vehicles, a faulty brake switch signal can confuse the computer systems, potentially triggering the ABS or traction control warning lights on your dashboard.
Recalls and Technical Service Bulletins (TSBs)
While there were significant recalls for brake light switches on earlier (2000-2003) Ford Taurus models, there are no specific open recalls from Ford or the NHTSA for the brake light switch on the 2008-2019 model years. Always check for any recalls related to your specific vehicle's VIN, but widespread issues for this part in these years have not been officially noted.
Choosing the Right Aftermarket Brake Light Switch
When shopping for a replacement, you'll find several brands available. Making the right choice depends on your budget and preference for originality.
- OEM (Motorcraft): Motorcraft is Ford's official parts brand. Choosing a Motorcraft switch guarantees a perfect fit, function, and compatibility with your Taurus's electronics. For a critical safety part, OEM is often the most reliable choice, though it comes at a higher price.
- Premium Aftermarket (Standard Ignition, Vemo): Brands like Standard Ignition (SMP) have a long-standing reputation for producing quality electronic components that meet or exceed OEM specifications. They are a trusted choice for mechanics and a solid alternative to the dealer part.
- Standard Aftermarket (Dorman, Holstein, True Tech): These brands offer a good balance of quality and value. Dorman is well-known for providing replacement parts that often include design improvements over the original. They are a popular and generally reliable option for a straightforward part like a brake light switch.
Pro Tip: Check the Connector
Before ordering, it's a good idea to look at your existing switch. The 2008-2019 range covers two different Taurus generations (2008-2009 and 2010-2019), and there may be slight variations in the electrical connector. Matching your new part to the old one visually can prevent ordering mistakes.

Frequently Asked Questions
Can I replace the Ford Taurus brake light switch myself?
Yes, this is a very DIY-friendly job. The switch is located on the brake pedal bracket under the dashboard. The process typically involves disconnecting the electrical connector, twisting the old switch to remove it, and then installing the new one in reverse order. The entire job can usually be done in under 30 minutes with no special tools.
🎬 See this step-by-step walkthrough for replacing the switch yourself.Why won't my Taurus shift out of park even after replacing the switch?
First, check the fuse for the brake light circuit to ensure it isn't blown. Also, ensure the new switch is installed and adjusted correctly; if it's not positioned properly, it won't activate. If the fuse is good and the switch is installed correctly, the problem could lie with the shift interlock solenoid itself or the associated wiring.
🎬 Watch: Troubleshooting tips if your Taurus still won't shift after replacement.Do I need to disconnect the battery to replace the switch?
It is always recommended to disconnect the negative battery terminal before working on any electrical components to prevent short circuits or blown fuses.
Could a bad bulb cause the same problems?
A burnt-out brake light bulb will not cause issues with the shift interlock or cruise control. Those symptoms point directly to the switch or its circuit. However, if your only symptom is a non-working brake light, you should check the bulbs and fuses first before replacing the switch.
