A-NAFTULY Blower Motor Resistor YH-1715 — Direct-Fit for Ford/Lincoln/Mercury (2005–2014), Restores Fan Speed Control

The A-NAFTULY YH-1715 blower motor resistor is a direct-fit replacement that restores multi-speed control to compatible Ford, Lincoln and Mercury HVAC systems.

If your vehicle’s heater or air conditioner only works on one fan speed, or stops blowing entirely, a failed blower motor resistor is often the culprit. The A-NAFTULY YH-1715 is engineered as a plug-and-play replacement for a wide range of Ford, Lincoln and Mercury models from the mid-2000s through early 2010s, matching common OEM part numbers so you can swap it with confidence.

Will this resistor fit my truck or SUV?

Check compatibility by year, make and model and by confirming the listed interchange part numbers. This resistor is made for manual HVAC control systems on many Ford and related vehicles; using the cross-reference numbers helps prevent ordering the wrong unit.

• Fits many Ford models: F-150 (2004–2014), F-250/F-350 Super Duty (2008–2010), Expedition (2007–2017), Escape (2008–2012), Mustang (2005–2009), Fiesta (2011–2013).
• Also fits Lincoln Mark LT (2006–2008) and Mercury models including Mariner (2008–2011), Montego (2005–2007).
• Cross-reference part numbers: YH1715, 3F2Z-18591-AA, 3F2H-19A706-AB, 973444 and others for verification.

How does replacing the resistor fix my HVAC performance?

The blower motor resistor governs the fan’s multiple speed steps for heating and cooling. When resistors fail they often cause the fan to be stuck at one speed or not operate; replacing the resistor restores normal speed selection and airflow control without replacing the entire blower assembly.

• Restores stepped fan speeds for proper cabin airflow control.
• Fixes symptoms like fan stuck on high or no blower operation.
• Saves cost compared with replacing the entire blower motor when only the resistor is faulty.

Is the A-NAFTULY YH-1715 easy to install?

Yes — this module is designed as a direct-fit OEM-style replacement and mounts in the same location as the factory part. Basic hand tools are generally all you need and the module is accessed from the lower passenger side in most applications.

• Direct replacement that meets or exceeds OEM fit standards.
• Located on lower passenger side for straightforward access in most models.
• Remove screws, unplug connector, swap resistor and reinstall; no special tools required.

What comes in the package and what warranty is offered?

The product ships as a single blower motor resistor assembly ready for installation, backed by a warranty to protect your purchase. A-NAFTULY provides customer support and warranty coverage if you run into fitment or performance issues after installation.

• Includes one A-NAFTULY YH-1715 blower motor resistor assembly.
• 18-month limited warranty and 24/7 customer service support.
• Tested materials and quality checks to ensure durability and proper operation.

Who this is for: Drivers and mechanics who need a reliable, cost-effective replacement for a faulty blower motor resistor on compatible Ford, Lincoln or Mercury vehicles. If your HVAC fan is behaving erratically or stuck at a single speed and your vehicle matches the listed years and part cross-references, the A-NAFTULY YH-1715 offers a straightforward repair that returns full fan-speed control without replacing the blower motor itself.
