Ford Excursion Cruise Control Release Switch: A Critical Replacement Guide (2000-2005)
This is more than a cruise control part; it's a critical safety component to prevent a potential fire in your Ford Excursion.
- This switch is a known fire hazard; inspect yours immediately for leaks.
- The relevant safety recall is NHTSA 09V399000. The recall fix (a fused harness) does not mean the switch itself is new.
- If the switch is leaking, park the vehicle outside and do not drive it until the switch is replaced.
- Replacement is simple, requiring basic tools, and is a great DIY task for any Excursion owner.
A Critical Safety Warning: Fire Risk and Recalls
URGENT: The original cruise control release switch on 2000-2003 Ford Excursions is a known fire hazard. This led to one of the largest recalls in automotive history (NHTSA Campaign ID: 09V399000, Ford Recall: 09S09). The switch can leak brake fluid internally, causing an electrical short that can lead to a fire under the hood, even while the truck is parked and turned off. 🎬 Watch: See how a faulty switch can cause a random fire. Ford's recall fix was to install a fused wiring harness to prevent a fire, but this did not always include replacing the switch itself. If your switch is leaking, it must be replaced immediately, regardless of whether the recall service was performed.
Symptoms of a Failing Cruise Control Release Switch
Pay close attention to these signs. Some indicate a minor inconvenience, while others point to a critical safety failure.
- Leaking Brake Fluid (Critical): The most serious symptom is visible brake fluid on or around the switch on the master cylinder. If you see this, do not drive the vehicle.
- Smoke or Burning Smell (Critical): Smoke or a burning plastic smell from the driver's side of the engine bay is a sign of the switch overheating and requires immediate attention.
- Cruise Control Won't Disengage (Serious): If you press the brakes and the cruise control stays on, the switch has failed in a dangerous way. You must turn the system off manually with the steering wheel controls.
- Cruise Control Inoperative: The most common non-critical symptom is that the cruise control simply won't turn on or set.
- Intermittent Operation: The cruise control may work sometimes or cut out unexpectedly while driving.
- Blown Fuses: The shorting switch may repeatedly blow the fuse associated with the cruise control or brake light circuits.
Choosing the Right Aftermarket Part
When replacing this critical switch, you have a choice between OEM and aftermarket options.
- OEM (Motorcraft): The original Ford part is typically sold as a kit (Part # 1L1Z-9F924-AA or SW6350) that includes a redesigned switch and a new fused wiring harness. This is a high-quality option but often comes at a higher price.
- Aftermarket (Standard Ignition): Reputable aftermarket brands like Standard Ignition provide a direct replacement for the switch itself. This is a cost-effective solution for replacing a leaking or non-functional switch, especially if your vehicle already has the fused recall harness installed. An aftermarket switch provides a new, reliable part that meets or exceeds the specifications of the failure-prone original.
Pro Tip: Replacing the switch is a simple DIY job. It unscrews from the master cylinder with a 7/8" wrench. Pre-filling the new switch with a few drops of fresh brake fluid before installation can help prevent air from entering the brake lines, potentially avoiding the need to bleed the brakes.

Frequently Asked Questions
Is my 2004 or 2005 Excursion affected by the recall?
The major fire recall (09V399000) officially covers 2000-2003 Excursions. However, Ford used similar switch designs across many models and years. While not under the same recall, owners of 2004-2005 models should still inspect the switch for leaks as a precaution, as any part can fail with age.
How can I check if the recall was performed on my Excursion?
Look at the wiring connected to the switch on the brake master cylinder. If you see an extra wiring adapter with a blue tag or a noticeable fuse holder between the switch and the main vehicle harness, the recall service was likely performed. You can also check your VIN on the NHTSA website.
🎬 Watch: How to check and fix this deadly fire hazard.If the recall was done, why should I replace the switch?
The recall's fused harness is a safety net designed to prevent a fire by cutting power during a short. It does not prevent the switch itself from failing and leaking. A leaking switch can still make your cruise control inoperative and is a sign that the part has failed and should be replaced.
Is this the same as the brake light switch on the pedal?
No. The Ford Excursion has two switches. The one on the brake pedal controls your brake lights. The one this article discusses is mounted under the hood on the brake master cylinder and is specifically for deactivating the cruise control.
