CTIMF Blower Motor Resistor BL3Z19E624A for Ford Expedition 2009-2017 — Direct-Fit Copper-Core

CTIMF BL3Z19E624A is a direct-fit replacement blower motor resistor that restores multi-speed HVAC fan control for compatible 2009–2017 Ford and Lincoln trucks and SUVs.

If your vehicle’s blower only works on one speed or not at all, a failing resistor is a common cause. This CTIMF unit—also referenced as YH1829 or BL3Z-19E624-A—matches the original fit and electrical function for select Ford Expedition, F-150, Lobo, Lincoln Mark LT and Lincoln Navigator models equipped with automatic AC controls. It’s built with a copper-core socket and durable materials to resist heat, impact and aging, and it is tested before shipping to meet or exceed OEM standards.

How will this blower motor resistor fix my HVAC fan problem?

When a blower resistor fails, one or more fan speeds stop working because the resistor no longer drops the electrical current correctly. Replacing the resistor reinstates proper current flow to the blower motor, restoring all speed settings when the rest of the HVAC system is functional.

• Direct-fit replacement for specified 2009–2017 Ford and Lincoln models with automatic AC controls.
• Restores lost fan speeds and prevents overheating of the blower circuit.
• Tested before shipping to ensure reliable operation out of the box.

Is the CTIMF BL3Z19E624A easy to install in my truck?

Yes — installation is straightforward and typically completed in under 30 minutes with basic hand tools. The resistor mounts into the blower motor housing and connects to the factory electrical plug, following the same location and method as the original part.

• Remove screws securing the blower motor resistor to access the assembly.
• Unplug the electrical connector, swap the old resistor for the CTIMF unit, then resecure with the factory screws.
• No modifications or wiring changes required for compatible vehicles.

What materials and quality checks ensure durability?

This resistor is manufactured with a copper-core socket and components selected for impact resistance, heat tolerance and longevity. Those material choices help prevent poor connections and reduce the risk of burning from excessive current, while pre-shipment testing confirms functional performance.

• Copper-core socket for reliable electrical contact and current handling.
• Heat- and aging-resistant construction for longer service life.
• Meets or exceeds OEM standards and is tested before shipping.

Will this part match my vehicle’s part number and controls?

This resistor is supplied under reference numbers YH1829, BL3Z-19E624-A and BL3Z19E624A to match OEM cross-references. It fits only models equipped with automatic AC controls, so verifying model year and control type ensures correct compatibility.

• OEM reference compatibility: YH1829 / BL3Z-19E624-A / BL3Z19E624A.
• Compatible with 2009–2017 Ford Expedition and Lincoln Navigator; 2009–2014 Ford F-150, Lobo, Lincoln Mark LT.
• Only for vehicles with automatic HVAC controls—manual-control variants are not supported.

Who is this for: Technicians, DIY truck owners and fleet managers who need a reliable, OEM-matching blower motor resistor for affected Ford or Lincoln vehicles. If your fan has lost speeds or the blower operates inconsistently and your vehicle uses automatic AC controls, the CTIMF BL3Z19E624A offers a tested, easy-to-install replacement. Contact CTIMF customer support within 12 working hours if you encounter issues; the part is backed by replacement or refund options for peace of mind.
