Understanding the Cruise Control Switch in Your 1998-2007 Navigator
If you own a 1998-2007 Lincoln Navigator, the cruise control release switch is a part you need to know about. While it seems minor, a failure can range from annoying—your cruise control not working—to extremely dangerous. This is especially true for earlier models due to a major safety recall.
CRITICAL RECALL: Fire Risk for 1998-2002 Navigators
Ford issued a massive recall for millions of vehicles, including the 1998-2002 Lincoln Navigator, for a faulty cruise control release switch. The original switch, made by Texas Instruments, had a seal that could fail over time, allowing flammable brake fluid to leak into the switch's electrical components. Because the switch is always powered, this leak could cause a short circuit and lead to an under-hood fire, even while the vehicle was parked and unattended. Many vehicle and home fires were attributed to this defect. The recall fix involved installing a fused wiring harness to prevent a fire. If your Navigator falls in this year range, you must verify this recall was performed. You can check with a dealer or use your VIN on the NHTSA website.
🎬 Watch: How to check if your vehicle has this fire hazardSymptoms of a Failing Cruise Control Release Switch
A bad switch can cause several problems. Look out for these common signs:
- Cruise Control Won't Turn On: The system may not engage at all if the switch is stuck in the 'off' position.
- Cruise Control Won't Turn Off With Brakes: This is a serious safety issue. If you tap the brakes and the cruise control stays on, the switch has failed.
- Cruise Control Won't Resume: After tapping the brakes to disengage, you may find the 'resume' function no longer works.
- Warning Lights: A faulty switch can sometimes trigger the ABS or brake warning light on your dashboard. 🎬 See this guide on diagnosing and repairing cruise control failures
- Visible Leaks: You may see brake fluid leaking from the switch or corrosion on the electrical connector where it plugs in.
Choosing the Right Aftermarket Part: OEM vs. Aftermarket
For a part tied to such a serious recall, quality is key. The original OEM switches were clearly defective. The recall replacement parts and later designs are safer. When shopping for a new aftermarket switch, you want a reliable brand.
Standard Ignition (Standard Motor Products) is a well-regarded aftermarket manufacturer that produces replacement switches for the Navigator. They often supply parts directly to vehicle manufacturers and have a reputation for quality that can meet or exceed original specs. When buying, be aware that SMP sometimes offers multiple product lines. Their standard line (often in a red box) is recommended over any lower-cost 'T-Series' economy line (often in a green box) to ensure better durability.
Pro Tip: When replacing the switch, it's a good idea to also get the pigtail connector or wiring harness. Brake fluid from a leaking old switch often damages the original connector, and replacing it ensures a solid, safe connection.

Frequently Asked Questions
Is it safe to drive with a bad cruise control release switch?
For 1998-2002 models, if the recall has not been performed, it is not safe. There is a risk of fire even when the vehicle is off. For all models, if the switch prevents the cruise control from disengaging with the brake pedal, you should stop using the cruise control system until it is repaired.
Where is the cruise control release switch located?
You can find the switch screwed into the brake master cylinder in the engine bay, on the driver's side. It has a two-wire electrical connector attached to it.
What is the difference between the switch on a 2002 vs. a 2005 Navigator?
The 1998-2002 Navigators were equipped with the Texas Instruments switch that was prone to leaking and causing fires. Ford stopped using this specific switch design in models after 2003. While the switch on a 2003-2007 Navigator can still fail and cause cruise control problems, it uses a redesigned part that does not have the same widespread, documented fire risk.
Can I replace this switch myself?
Yes, this is a very straightforward DIY job for most home mechanics. It requires basic tools to unplug the connector and unscrew the old switch. Be prepared for a small amount of brake fluid to drip out when you remove the switch, and have the new one ready to install quickly to minimize fluid loss.
