Ford Escape, Focus, Transit & C-Max Combination Switch Issues: 2012-2023 Turn Signal and Headlight Faults

Symptoms of a Failing Combination Switch

A bad combination switch is one of the more common electrical issues on the 2013-2019 Ford Escape, 2014-2023 Ford Transit Connect, 2013-2018 Ford C-Max, 2012-2018 Ford Focus, and 2015-2019 Ford Transit vans. Because the internal electrical contacts wear out from repeated use, the symptoms can start intermittently and worsen over time. Look for these specific signs:

• Turn Signal Problems: This is the most frequent symptom. You might experience turn signals that don't work at all (neither the light on the dash nor the exterior bulb), work only on one side, or function intermittently. In some cases, the hazard lights might work correctly, 🎬 See why turn signals fail when hazards still work. but the individual turn signals will not.
• Headlight and High Beam Issues: You may have trouble turning the headlights on, or they might flicker. A very common failure is the inability to switch between low and high beams, or the high beams not staying on when you activate them.
• Incorrect Operation: Sometimes, strange electrical behavior can occur. For example, turning on a turn signal might cause the hazard lights or even dashboard lights to flash. This points to a short circuit inside the switch assembly.
• Wiper or Cruise Control Malfunctions: While this specific switch primarily handles lighting, on some vehicle platforms, related wiring in the steering column can be affected. Problems with wipers or cruise control can sometimes be linked to a failing combination switch or the clockspring it connects to.

Buying a Used Combination Switch: What to Check

A recycled OEM combination switch is an excellent, cost-effective alternative to expensive new parts or lower-quality aftermarket options. Since this part does not require programming, a used unit from a compatible vehicle is a simple plug-and-play replacement. Here’s what to look for:

1. Verify the Part Number: The best way to ensure compatibility is to match the part number. Look for OEM numbers like F1FZ-13341-A, which supersedes the older CV6Z-13341-A. Other engineering numbers printed on the switch itself, like CV6T-13335-AD, can also be used for matching.
2. Physical Inspection: Check the plastic housing for any cracks or stress marks, especially around the mounting points. Ensure the stalk moves smoothly through its functions (up, down, forward, back) with a solid clicking feel. It should not feel loose, gritty, or sloppy.
3. Check the Markings: The graphics printed on the stalk for the headlight and turn signal functions should be clear and not worn away. This is often an indicator of how much use the switch has seen.
4. Inspect Electrical Connectors: Look at the connector pins. They should be straight, clean, and free of any green or white corrosion. Corroded pins indicate moisture exposure and the switch should be avoided.
5. Ask About the Donor Vehicle: If possible, get the mileage from the vehicle the part came from. While these switches don't have a set lifespan, one from a lower-mileage vehicle is generally a better choice. Confirm the donor vehicle did not have lane-keeping features.

Known Issues, TSBs, and Recalls

While there are numerous recalls and Technical Service Bulletins (TSBs) for the Ford Focus, Escape, C-Max, and Transit models, none specifically target the combination switch for a widespread manufacturing defect. The failures are typically due to normal wear and tear on the internal mechanical and electrical contacts.

Some related issues for these vehicles include:

• 2015 Ford Escape, Focus, C-Max: A recall was issued for a body control module (BCM) defect that could cause the engine to continue running after the key was turned off. While not directly a combination switch issue, it highlights the complex electrical systems in these vehicles.
• 2012-2018 Ford Focus: A major recall (18S32) was issued for a faulty canister purge valve that could deform the fuel tank, leading to stalling and inaccurate fuel gauge readings. This is unrelated to the combination switch but is a critical safety issue for owners to be aware of.
• 2014-2015 Ford Escape & Transit Connect: A recall was issued for a software issue that could cause the instrument panel cluster to go blank.

No specific TSBs or recalls point to a systemic problem with the combination switch itself across this wide range of vehicles. Failures are treated as a standard repair item.

Cost Comparison

Replacing the combination switch is a relatively affordable repair. The part itself is not expensive, and the labor is straightforward.

Replacement Overview & Difficulty

Replacing the combination switch is a job most DIY mechanics can handle with basic tools.

• Difficulty: 2 out of 5
• Estimated Time: 0.5 - 1 hour
• Tools Needed: Phillips screwdriver, small flathead screwdriver or trim removal tool, 5.5mm socket, T10 Torx driver.

The general process involves:

1. Disconnect the Battery: This is a crucial safety step before working on any electrical components.
2. Remove Steering Column Covers: Remove the three 5.5mm screws from the bottom plastic cover of the steering column and carefully pry the top and bottom halves apart.
3. Unplug and Remove the Switch: The switch is typically held to the steering column with one or two Torx screws. Remove the screws, carefully unplug the electrical connector, and slide the old switch out.

4. Install the New Switch: Slide the new switch into place, secure it with the screws, and plug in the electrical connector.
5. Reassemble and Test: Snap the steering column covers back together, reinstall the screws, and reconnect the battery. Test all functions of the new switch (turn signals, high/low beams) to ensure proper operation.
