Product Details

This Four Seasons 73010 HVAC blend door actuator is used to control airflow direction and temperature blend inside the HVAC system. It is listed for 1993-2011 Ford Crown Victoria with manual AC, 1994-2011 Mercury Grand Marquis with manual AC, and 1994-2004 Ford Grand Marquis with manual AC. It also fits 2003-2004 Mercury Marauder, with the note that the ATC relay connector is incompatible with the HVAC blower motor resistor harness. The Four Seasons 73010 is a practical replacement when the original actuator no longer moves the blend door correctly or the HVAC system loses proper temperature control.

Common Issues This Part Can Address

• Inconsistent cabin temperature control
• Blend door movement that stops or binds
• HVAC airflow stuck on one temperature setting
• Clicking or repeated actuator noise from the dash HVAC case
• Loss of proper air door response in manual AC systems

Installation Notes and Tips

Verify the vehicle uses manual AC before ordering. Match the arm-style linkage, 4-ear mounting pattern, and 8-pin connector to the original unit before installation. On 2003-2004 Mercury Marauder applications, confirm the ATC relay connector note against the HVAC blower motor resistor harness before replacement. Access is typically through the HVAC housing, so compare the original actuator position and connector orientation before removal.
