Detailed Description

The Autotecnica FD0618710 is an aftermarket HVAC blower motor resistor for vehicles that use a resistor-based blower speed circuit. It is designed for select 2006-2012 Ford Fusion, 2007-2012 Lincoln MKZ, 2006-2011 Mercury Milan, and 2006 Lincoln Zephyr models. If your Ford Fusion, Lincoln MKZ, or Mercury Milan has lost one or more fan speeds, this resistor is a direct replacement option for diagnosing and correcting blower control issues. This part cross-references Dorman OE Solutions 973-057 for the same application.

What It Helps Fix

• Blower motor works only on certain speeds
• Cabin fan stops responding at lower or higher settings
• Intermittent HVAC fan operation
• No airflow from the vents due to resistor failure
• Electrical resistance issues in the blower control circuit

Installation Notes and Tips

Verify connector style, terminal count, and mounting layout before installation. This FD0618710 resistor uses a rectangular female connector with 5 male blade terminals and a single bolt-hole mount, so matching the original part configuration is important for proper fitment. Inspect the blower motor connector and surrounding HVAC wiring for heat damage before installing the new resistor.
