Larlansz Front Passenger Power Seat Switch for Ford/Lincoln/Mercury — Right-Side 12‑Pin Direct-Fit, Restores Seat Movement (2006–2

A direct-fit front passenger electric seat adjustment control switch from Larlansz engineered to replace worn or faulty OEM part numbers 9L3Z14A701FA / DE9Z14A701BA and restore full seat movement in compatible Ford, Lincoln, and Mercury models.

If your vehicle’s front passenger power seat stopped moving, the internal plastic gears or electrical contacts in the original switch are often the culprits. This Larlansz replacement is designed to match the shape, mounting points, and 12-pin connector layout of the factory unit so installation is straightforward and the controls feel familiar. It's sold as the right-side (front passenger) power seat adjustment control and is intended for a range of Ford, Lincoln, and Mercury vehicles from model years 2006–2019 when they use the specified connector and form factor.

Which vehicles will this seat switch fit?

This switch is compatible with many Ford, Lincoln, and Mercury vehicles when they originally used the referenced OEM part numbers and a 12-pin connector. Always verify your vehicle’s connector and part number before ordering to ensure proper function.

• Ford: F150 (2009–2014), F250/F350/F450/F550 (2009–2019), Explorer (2006–2015), Expedition (2007–2017), Edge (2007–2014), Fusion (2006–2012), Taurus (2010–2018), C-Max/Escape (2013–2018), Police Interceptor Sedan (2013–2019)
• Lincoln: MKT (2013–2019), Navigator (2007–2017), MKX (2007–2015), MKZ (2007–2012), Mark LT (2010–2014)
• Mercury: Milan (2006–2011), Mountaineer (2006–2010)
• Compatible when vehicle uses 12-pin frontal passenger seat connector matching the OEM pattern

How does this replacement compare with the original OEM switch?

The Larlansz unit is manufactured to mirror the fit and function of the factory switch so it installs like the original and restores the same range of seat adjustments. It is a direct replacement meant for vehicles whose original assembly failed from wear rather than electrical system issues elsewhere.

• Form-matched housing and mounting points for straightforward swap-in replacement
• 12-pin connector layout matching the listed OEM numbers for compatibility
• Durable actuator components intended to replace fatigued factory parts
• Delivered as the passenger-side (front right) adjustment control

What do I need to check before buying and installing?

Confirming connector pin count, part number, and that the issue is the switch itself prevents returns and installation problems. If seat motors or harness wiring are damaged, replacing the switch alone will not restore movement.

• Verify the OEM part number stamped on your original switch or vehicle service manual
• Ensure the seat connector has 12 pins and matches the Larlansz plug pattern
• Test for power and ground at the connector if unsure where the failure lies
• Disconnect the battery before swapping electrical components to avoid short circuits

How difficult is installation and what tools are needed?

Installation is typically straightforward for a DIYer comfortable with interior trim removal: remove the seat trim or bezel, unplug the old switch, and reinstall the new unit. No special programming is required because this is a mechanical/electrical switch replacement rather than a module.

• Common tools: trim pry tools, Phillips or Torx driver depending on vehicle fasteners
• Time: usually 30–60 minutes when access is straightforward
• Safety: disconnect battery negative terminal before starting
• If in doubt, consult a professional technician for diagnosis and fitting

Who is this for: Drivers and technicians who need a reliable, OEM-style replacement for a failed front passenger (right-side) power seat adjustment switch on compatible Ford, Lincoln, and Mercury vehicles from roughly 2006–2019. Ideal when the original switch shows worn controls, intermittent operation, or broken actuators and the vehicle uses the 12-pin connector and matching OEM part numbers.
