Guide to the 2007-2017 Lincoln Navigator Window Motor and Regulator
Diagnose and fix your Navigator's common power window problems for good.
- The window regulator fails more often than the motor; listen for motor sounds to diagnose the correct part.
- Aftermarket brands like Dorman and Cardone offer reliable, cost-effective replacements for the full assembly.
- After installation, the window's auto up/down feature must be re-initialized for proper function.
- There are no recalls for this common issue; it is considered a standard wear-and-tear repair.
Is It the Motor or the Regulator?
On the 2007-2017 Lincoln Navigator, the window regulator is the most common point of failure, not the electric motor itself. The regulator uses cables and plastic clips that can wear out, stretch, or break over time. Before buying a new motor, it's important to know which part has failed.
- Listen to the Door: Press the window switch. If you hear a whirring, grinding, or clicking sound from the motor, but the window doesn't move or moves incorrectly, the regulator is almost certainly the problem. The motor is trying to work, but the mechanical parts are broken. 🎬 Watch: Step-by-step front window regulator replacement guide.
- If You Hear Silence: If you press the switch and hear nothing at all, the issue is likely electrical. This could be a dead motor, a bad window switch, a blown fuse, or damaged wiring in the door jamb. Always check the fuse first.
Pro Tip: Reuse Your OEM Motor
The original factory (OEM) motors on these Navigators are known to be very reliable and robust. If you diagnose a bad regulator but your original motor still works, you can often save money by purchasing just the window regulator and transferring your old motor to the new assembly. However, many aftermarket parts are sold as a complete motor and regulator assembly for convenience.
Common Failure Symptoms
A failing window motor or regulator will give you clear warning signs. Ignoring them can lead to a window that's stuck open, posing a security and weather risk.
- Grinding or Popping Noises: A loud crunch or pop when you hit the switch often means a regulator cable has snapped.
- Slow or Jerky Movement: If the window struggles to go up or down, the motor is straining or the regulator cables are binding.
- Crooked Window: A window that tilts to one side in the frame indicates a broken guide clip on the regulator.
- Window Drops into Door: This is a complete regulator failure, where the glass is no longer supported and falls into the door panel.
Choosing an Aftermarket Window Motor
For the 2007-2017 Navigator, new aftermarket window motors and assemblies from brands like Dorman and Cardone are popular, cost-effective alternatives to expensive OEM parts.
- Dorman: A widely available brand that offers direct-fit replacement motors and full assemblies. They are generally considered a reliable, mid-tier option that gets the job done and often comes with a good warranty.
- Cardone: Known for both new and remanufactured parts, Cardone provides a dependable, budget-friendly choice that is rigorously tested.
Both brands offer a practical solution for restoring your power windows. Since the labor for replacement is the same regardless of the brand, choosing a part with a lifetime warranty can provide peace of mind.
Important: Window Initialization Required
After replacing the window motor or disconnecting the battery, you will likely need to re-initialize the window's auto up/down feature. This is a simple procedure that involves a sequence of key turns and holding the window switch. If you skip this step, the one-touch function will not work correctly.

Frequently Asked Questions (FAQ)
Do I have to replace the whole motor and regulator assembly?
No, the motor and regulator can be purchased and replaced separately. However, it is often more convenient to replace them as a single unit, and many aftermarket parts are sold this way. If your regulator failed, it may have put extra strain on the original motor, so replacing both can be a good preventative measure.
Are there any recalls for the window motor on my Navigator?
No, there are no safety recalls or technical service bulletins (TSBs) for window motor or regulator failure on the 2007-2017 Lincoln Navigator. The problem is considered a wear-and-tear item. A recall for the 2018 model year concerned a different part of the window control system and does not apply to this generation.
Is the replacement process the same for front and rear doors?
The general process of removing the door panel and accessing the components is similar, but the parts themselves are different. Window regulators and motors are specific to each door (front left, front right, rear left, rear right), so be sure to order the correct part for the specific window 🎬 See how to replace the driver's side rear window regulator. you are repairing.
