HIMARKLIF Blower Motor Resistor Kit with WPT688 Harness — Fits Ford Expedition/F-150 2009–2017, Restores Multi-Speed Fan Control

HIMARKLIF HVAC Blower Motor Resistor Kit restores blower fan speed control and includes a WPT688 connector harness for compatible 2009–2017 Ford and Lincoln models.

This replacement kit supplies the blower motor resistor assembly and a free WPT688 wiring connector harness designed to fit automatic climate control systems in select Ford and Lincoln vehicles. Built to meet or exceed OEM sizing and durability, the kit targets common blower issues such as lost fan speeds, intermittent airflow, or total fan failure. Easy to access beneath the passenger-side dash, installation requires only basic tools and a few minutes for most DIYers.

How will this resistor kit affect my vehicle’s heating and cooling?

Replacing a failing blower motor resistor reestablishes the stepped fan speeds controlled by your vehicle’s AC/heater interface, allowing consistent airflow across temperature settings. The kit’s components resist overheating and thermal-fuse failure for improved longevity compared with worn or corroded originals.

• Restores multi-speed fan control for automatic AC systems
• Helps prevent intermittent blower operation and sudden stops
• Durable construction reduces risk of thermal burnout
• Includes matching WPT688 connector for secure electrical fit

Which models and years will this part fit?

This HIMARKLIF resistor and harness set is designed specifically for certain Ford and Lincoln vehicles that use automatic temperature control. Confirm that your vehicle uses automatic AC controls before ordering to ensure compatibility and proper operation.

• Ford Expedition: 2009–2017
• Ford F-150: 2009–2014
• Lincoln Navigator: 2009–2017
• Lincoln Mark LT: 2010–2014 (auto temp control only)

What does installation involve and how long does it take?

Installation is straightforward for most people familiar with basic hand tools. The resistor sits on the lower passenger-side dash and is secured by a few screws; swapping the old unit for the HIMARKLIF kit typically takes minutes rather than hours.

• Locate blower resistor on lower passenger dash behind panel
• Remove mounting screws, unplug original harness, and extract old resistor
• Plug in provided WPT688 connector and secure new resistor with screws
• No special programming required — direct replacement fit

What’s included and which part numbers does it replace?

The package contains one blower motor resistor assembly plus one WPT688 connector wire harness. It replaces multiple factory and aftermarket references so you can match the part to your vehicle’s existing numbers.

• Included: 1 x blower motor resistor, 1 x WPT688 connector harness
• Replaces: BL3Z-19E624-A, BL3Z19E624A, YH-1829, YH1829
• Connector reference: WPT688 and 3U2Z14S411ZEA
• Meets or exceeds OEM dimensional and electrical standards

Who is this for: The HIMARKLIF HVAC Blower Motor Resistor Kit is aimed at owners and technicians working on 2009–2017 Ford Expeditions and Lincoln Navigators, 2009–2014 F-150s, and 2010–2014 Lincoln Mark LTs equipped with automatic climate control who need a reliable, direct-fit replacement. If your blower fan only works on certain speeds, stops unexpectedly, or you need a ready-to-install harness for a secure electrical connection, this kit offers a cost-efficient repair alternative to replacing the entire blower motor assembly.
