Detailed Description

Dorman 973-485 is an HVAC blower motor resistor designed to restore blower speed control when the factory resistor burns out or stops regulating current correctly. This part is built as a direct replacement for select Ford F-150, Ford Freestar, Lincoln Mark LT, Lincoln LS, and Ford Thunderbird applications, helping return normal heating and cooling functionality. The included wire harness and connector layout support a repair that follows the original vehicle configuration, and the part cross-references 3F2Z19E624AB for the same application.

For buyers searching for a blower motor resistor for 2004-2008 Ford F-150 automatic air conditioning controls, or a replacement resistor for 2004-2007 Ford Freestar front HVAC systems, this part number 973-485 is a direct-fit option to review against your vehicle’s connector and control setup.

What It Helps Fix

• Blower motor only working on certain speeds
• No cabin airflow from the HVAC vents
• Intermittent fan operation
• Loss of heating or cooling output due to resistor failure
• Electrical overheating damage at the resistor connector

Installation Notes and Tips

Verify the connector shape, terminal count, and harness layout before installation. This resistor uses a rectangle connector, 4 blade terminals, and a female connector design with the harness included. Mounting hardware is not included, so reuse the existing fastener if serviceable. Confirm vehicle-specific HVAC control type and position before ordering, especially on Ford F-150 and Ford Freestar applications with automatic air conditioning controls.
