BL3Z-19E624-A Blower Motor Resistor

Key Features

  • Regulates the fan speed of the vehicle's HVAC system.
  • Direct replacement for the original equipment component.
  • Engineered for vehicles equipped with automatic temperature control.
  • Constructed from durable plastic and aluminum for heat and corrosion resistance.

Replaces / Cross-Reference Part Numbers

  • BL3Z-19E624-A
  • BL3Z19E624A
  • YH-1829

Compatibility & Fitment

  • Ford F-150 (2009-2014)
  • Ford Expedition (2007-2017)
  • Ford Escape (2008-2012)
  • Note: For models with Dual Zone Automatic Temperature Control.

When to Replace

  • HVAC fan only operates on one speed (typically high).
  • Fan speed cannot be adjusted.
  • Blower motor is not functioning on any setting.
  • Burning smell from the passenger side dashboard area.

Installation Tips

  • Disconnect the vehicle's negative battery terminal before beginning work.
  • The resistor is typically located in the HVAC housing, accessible from the passenger-side footwell.
  • Inspect the electrical connector for signs of melting or corrosion and replace if necessary.
  • Ensure the new resistor is securely mounted and the electrical connection is firm.

4 SIMPLE STEPS

4 SIMPLE STEPS

1. Access to your resistor (usually behind/ under the glove box); 2. Release the 2 screws that secure the resistor to the housing; 3. Unplug the wire harness from the resistor connector by carefully releasing its tab with a flat-head screwdriver; 4. Reinstall with the new resistor. You can put some dielectric grease on in the resistor connector housing to avoid water intrusion.

FAQ

This part is designed for Ford F-150 (2009–2014), Ford Expedition (2009–2017), and Lincoln Navigator (2009–2017) models equipped with Automatic Temperature Control (ATC) systems.
This unit replaces OEM part number BL3Z-19E624-A. It also cross-references with YH-1829, BL7C3Z19E624C, and 9L3Z19E624B.
Common symptoms include the blower motor running at only one speed, the fan failing to turn on at all, or the fan speed fluctuating erratically despite your settings. If you have automatic climate control and the fan speed does not adjust as the cabin reaches the target temperature, the resistor module is often the culprit.
No. This specific resistor module is engineered exclusively for vehicles equipped with Automatic Temperature Control (ATC) systems. It will not function correctly in vehicles with manual climate control knobs.
Before installing the new module, inspect the wiring harness connector for signs of melting, corrosion, or heat damage. If the connector pins are burnt, simply replacing the resistor may not solve the issue, as a poor electrical connection will cause the new module to fail prematurely. Many technicians recommend replacing the pigtail connector if any heat damage is visible.
The installation is generally straightforward and can typically be completed in 30 to 60 minutes. The resistor is usually located under the passenger side dashboard near the blower motor housing. You will need basic hand tools, such as a socket set or screwdriver, to remove the access panel and secure the new module.
