CTIMF Blower Motor Resistor BL3Z19E624A for Ford/Lincoln 2009–2017 — direct-fit, copper-core socket restores fan speeds

The CTIMF BL3Z19E624A blower motor resistor restores variable fan speeds in compatible 2009–2017 Ford and Lincoln vehicles by replacing the worn resistor in the HVAC blower assembly.

If your vehicle’s fan is stuck on one speed or the blower stops responding to the dash controls, a failing blower motor resistor is often the cause. The CTIMF BL3Z19E624A is a direct-fit replacement designed to meet or exceed OEM performance for select Ford Expedition, F-150, Lobo, Lincoln Mark LT and Lincoln Navigator models with automatic AC controls. Built with a copper-core socket and durable materials, it’s intended to deliver consistent electrical contact and heat resistance for reliable HVAC operation.

How will this resistor restore my HVAC fan speeds?

Replacing a faulty resistor with the BL3Z19E624A re-establishes the electrical pathways that control the blower motor’s speed settings. The part replicates the original fit and function to allow the vehicle’s control module to regulate current and step through low-to-high fan speeds.

• Direct-fit design for specified Ford and Lincoln models with automatic AC controls
• Copper-core socket reduces poor connections and overheating
• Restores full range of blower speeds once installed
• Tested before shipping to meet performance expectations

Will installation take long and what tools do I need?

Installation is straightforward and typically completed in under 30 minutes by removing the blower motor screws, extracting the old resistor assembly, and installing the new unit. No advanced wiring or cutting is required because this is a plug-and-play replacement that matches OEM mounting points.

• Basic hand tools: screwdriver or socket set to remove blower motor screws
• No soldering—direct plug-in connector matches factory harness
• Simple steps: remove screws, swap resistor assembly, refasten screws
• Recommended: disconnect battery for safety before starting work

Which vehicles and part numbers is this compatible with?

The CTIMF BL3Z19E624A fits a range of Ford and Lincoln trucks and SUVs produced between 2009 and 2017, but only units equipped with automatic AC controls. It is referenced by OEM numbers YH1829, BL3Z-19E624-A and BL3Z19E624A for easier cross-checking.

• 2009–2017 Ford Expedition (automatic AC controls only)
• 2009–2014 Ford F-150, Lobo; 2009–2014 Lincoln Mark LT
• 2009–2017 Lincoln Navigator with automatic AC controls
• Matches OEM fit, function and performance for listed vehicles

What materials and quality features does this resistor offer?

CTIMF designed this resistor with a copper-core socket and durable housing to resist heat, impact and aging—addressing common failure points that cause intermittent blower operation. The construction aims to reduce poor electrical contact and prevent excessive current that can burn the blower circuit.

• Premium copper-core socket for reliable conductivity
• Heat- and impact-resistant materials for longer service life
• Manufactured to meet or exceed OEM standards and tested before shipping
• Backed by CTIMF support for replacement or refund if issues arise

Who is this for: The CTIMF BL3Z19E624A is intended for DIY mechanics and professional technicians repairing HVAC systems on compatible Ford and Lincoln models that have lost variable blower control. If your fan is stuck on one speed, not running at certain settings, or you’re restoring HVAC performance after diagnosing a resistor failure, this direct-fit replacement provides an OEM-style solution with a straightforward installation path.
