A Practical Guide to the 2008-2017 Lincoln Navigator Turn Signal Switch
Everything you need to know when your Navigator's turn signals, wipers, or high beams start acting up.
- The turn signal switch controls signals, wipers, and headlights; a failure can affect any of these systems.
- Before replacing the switch, always check for burnt-out bulbs and bad fuses first, as these are more common and cheaper to fix.
- Replacement is a simple DIY job that most owners can do in under an hour with basic tools.
- For best results, choose either the OEM Motorcraft part or a reputable aftermarket brand like Standard Ignition.
Is Your Navigator's Turn Signal Switch Failing?
When the multi-function switch in your Lincoln Navigator starts to fail, it can cause a range of confusing problems. Because the switch controls many different systems, you might see symptoms that don't seem related to the turn signals at first. Pay attention to these common signs that the switch may need replacement.
Choosing the Right Aftermarket Switch
When shopping for a new turn signal switch, you'll find Original Equipment (OEM) and aftermarket options. For your Navigator, the OEM brand is Motorcraft. Aftermarket brands like Standard Ignition (also known as Standard Motor Products or SMP) are also available.
- Motorcraft: This is the same part your Navigator was built with. It guarantees a perfect fit and original feel. However, it is the most expensive option. Forum users consistently recommend Motorcraft for those who want the highest quality and longest life without question.
- Standard Ignition (SMP): This is a well-regarded aftermarket brand often used by professional mechanics. It is designed to meet or exceed OEM specifications and offers a reliable, more affordable alternative to the dealer part.
| Part Type | Estimated Cost |
|---|---|
| New OEM (Motorcraft) | $125 - $190 |
| New Aftermarket (Standard Ignition) | $86 - $123 |
| Shop Labor | $100 - $150 |
Frequently Asked Questions
Is it safe to drive with a broken turn signal switch?
It is not recommended. A faulty switch can leave you without turn signals, which is a major safety hazard. In some cases, it can also affect your brake lights or headlights, making the vehicle unsafe to operate. You should get the switch replaced as soon as possible.
Can I replace the turn signal switch myself?
Yes, this is a very common DIY repair. The process involves removing the plastic covers around the steering column, unplugging the old switch, and installing the new one. It typically requires only basic hand tools and can be completed in under an hour.
My turn signals blink fast. Is the switch bad?
Usually, a fast-blinking turn signal (hyperflash) means you have a burnt-out bulb in the front or rear of your vehicle. Check all your turn signal bulbs first before assuming the switch is the problem. If all bulbs are working, you should then check the flasher relay before replacing the switch.
Are there any recalls for the Navigator turn signal switch?
No. Searches of the National Highway Traffic Safety Administration (NHTSA) database did not find any safety recalls specifically for the turn signal switch on the 2008-2017 Lincoln Navigator.
