By the end, you’ll have the confidence to tackle this repair and restore your Mustang’s lighting functionality safely.

Why the 2014 Mustang Headlight Switch Matters More Than You Think

The headlight switch in your 2014 Mustang isn’t just a simple dial or button; it’s a critical component of your vehicle’s electrical system. Beyond controlling the headlights, it often manages:

  • ​Parking lights and marker lights: Ensuring your car is visible when parked or driven at low speeds.

  • ​Daytime Running Lights (DRLs)​: If equipped, these rely on the switch to activate automatically.

  • ​Instrument panel lighting: Dimming or brightening your gauge cluster based on settings.

  • ​Multi-function switch integration: On many Mustangs, the headlight switch is part of a larger assembly that includes turn signal, wiper, and cruise control levers. A faulty switch can cause issues with these features too.

Common signs of a failing 2014 Mustang headlight switch include:

  • Headlights that don’t turn on, even when the switch is in the “on” position.

  • Intermittent flickering or dimming of lights.

  • The “auto” headlight setting (if equipped) failing to activate based on ambient light.

  • Other electrical quirks, like the interior dome light not syncing with door openings.

Ignoring these symptoms can lead to safety risks—imagine driving at night with non-functional headlights—or more expensive repairs if the issue damages other components, like the headlight relay or wiring.

Why Advance Auto Parts Is Your Best Bet for a 2014 Mustang Headlight Switch

Advance Auto Parts isn’t just another auto parts store; it’s a trusted resource for millions of DIYers and professionals. Here’s why it stands out for your 2014 Mustang headlight switch replacement:

1. ​Wide Selection of OEM-Quality and Aftermarket Parts​

Advance carries both ​OEM (Original Equipment Manufacturer)​​-style switches and high-quality aftermarket options. For your 2014 Mustang, you’ll find switches from brands like ACDelco—Ford’s trusted aftermarket partner—ensuring a perfect fit and reliable performance. Unlike generic parts found online, Advance’s inventory is curated to match specific vehicle years, makes, and models, reducing the risk of buying the wrong switch.

2. ​Local Inventory Check: Find Stock Near You in Minutes​

Advance’s website and mobile app let you check real-time stock levels at nearby stores. Simply visit advanceautoparts.com/store-locator, enter your ZIP code, and filter for “Headlight Switches.” You can even narrow results to “Ford” and “2014 Mustang” to see which stores have your exact part in stock. This saves you a wasted trip and ensures you get the right component without delay.

3. ​Expert Advice and Installation Support​

Advance’s in-store associates are trained to help with vehicle-specific repairs. If you’re unsure which switch to buy, bring your VIN (found on your dashboard or driver’s side door jamb) to the counter—they can look up the exact part number for your 2014 Mustang. Many stores also partner with local mechanics for installation services, though most DIYers can handle this swap with basic tools.

4. ​Warranty and Return Protection​

All headlight switches at Advance come with a limited lifetime warranty, meaning if the part fails prematurely, you can return it for a replacement. Plus, if you accidentally buy the wrong switch, you have 90 days to return it for a full refund (with receipt).

Step 1: Confirm Your 2014 Mustang’s Headlight Switch Type

Before heading to the store, it’s crucial to confirm which headlight switch your Mustang uses. The 2014 model year has two primary configurations:

  • ​Base and Premium trims: These typically use a rotary dial switch integrated into the multi-function lever (the same lever that controls turn signals and wipers).

  • ​GT and Shelby GT500 trims: Some higher-end models may have a slightly different switch, especially if equipped with adaptive lighting or HID headlights.

To verify, pop the hood and locate the headlight relay (in the Power Distribution Box under the hood). The relay’s part number can cross-reference to the switch, but an easier method is to note your Mustang’s VIN and ask an Advance associate—they can pull up the exact part number (e.g., ACDelco 19135435 or Motorcraft SW-6875).

Step 2: Locate the Nearest Advance Auto Parts Store with Stock

Once you have the part number, use Advance’s store locator to find nearby stores with your headlight switch in stock. Here’s how:

  1. Go to advanceautoparts.comand click “Store Locator” in the top menu.

  2. Enter your city, state, or ZIP code.

  3. In the “Category” dropdown, select “Electrical” > “Switches” > “Headlight Switch.”

  4. Filter results by “In Stock” to see which stores have your part.

Pro Tip: Call the store before visiting to confirm the part is still available—stock can change daily. Ask if they have a “Test Lane” where you can verify the switch works before leaving, or if they can bench-test it for you.

Step 3: Purchase the Right Headlight Switch (and Tools)

At the store, double-check the part number against your VIN to ensure compatibility. For a 2014 Mustang, you’ll need:

  • ​Headlight switch: ACDelco 19135435 (OEM-style) or equivalent.

  • ​Basic tools: Phillips-head screwdriver, flathead screwdriver, trim panel removal tool (optional but recommended to avoid scratching the steering column), and a test light or multimeter (to check for power).

Advance often bundles headlight switches with installation guides or cheat sheets—ask an associate for these free resources.

Step 4: Install the New Headlight Switch Yourself (Step-by-Step)

Installing a 2014 Mustang headlight switch is a straightforward DIY job that takes 30–60 minutes. Here’s how to do it safely:

​Safety First: Disconnect the Battery​

Before working on any electrical component, disconnect the negative (-) terminal of your Mustang’s battery using a wrench. This prevents short circuits or accidental airbag deployment (the multi-function lever is near the airbag module).

​Remove the Steering Column Trim​

  1. Lower the steering wheel to its lowest position.

  2. Use a trim panel removal tool (or a flathead screwdriver wrapped in tape to avoid scratches) to pry off the plastic covers around the multi-function lever. Start at the bottom and work upward.

  3. Once the covers are off, you’ll see two Phillips screws securing the lower trim piece. Remove these screws and gently pull the trim away from the column.

​Access the Headlight Switch​

The headlight switch is mounted to the steering column behind the multi-function lever. You’ll see a wiring harness plugged into the back of the switch.

​Disconnect the Old Switch​

  1. Squeeze the locking tab on the wiring harness connector and pull it straight out. Be careful not to tug on the wires—most connectors have a release mechanism.

  2. Note the position of the switch on the column (it’s held in place by a retaining clip or screw). For rotary dials, there’s usually a small screw on the side; loosen it with a Phillips screwdriver.

​Install the New Switch​

  1. Align the new switch with the mounting holes on the steering column.

  2. Tighten the retaining screw (if applicable) and push the switch into place until it clicks.

  3. Reconnect the wiring harness—ensure the connector snaps securely into place.

​Reassemble and Test​

  1. Put the steering column trim back in place, replacing the Phillips screws and plastic covers.

  2. Reconnect the battery’s negative terminal.

  3. Turn the ignition to the “on” position (don’t start the engine) and test all lighting functions: low beams, high beams, parking lights, and fog lights (if equipped).

  4. Adjust the dimmer switch (if your Mustang has one) to ensure the instrument panel lights brighten/dim correctly.

Troubleshooting Common Issues After Installation

Even with careful installation, you might encounter a few hiccups:

  • ​Lights still don’t work: Double-check the wiring harness connection—sometimes the connector isn’t fully seated. Use a test light to check for power at the switch; if there’s no power, inspect the fuse box (under the hood or in the cabin) for a blown fuse.

  • ​Switch feels loose: Ensure the retaining screw is tightened properly—over-tightening can strip the threads, so use steady pressure.

  • ​Other functions (wipers/turn signals) acting up: You may have accidentally disturbed the multi-function lever’s wiring. Recheck the trim pieces to ensure nothing is pinched.
