Detailed Description

This Four Seasons 73020 blend door actuator is used in HVAC systems that regulate airflow direction and cabin temperature. It is listed for 2010 Ford F-250 Super Duty and 2010 Ford F-350 Super Duty applications, including Main, Left Main, and Right Main positions as specified in the fitment data. For 2010 Ford F-250 Super Duty and 2010 Ford F-350 Super Duty trucks with manual HVAC control, this actuator serves the main air door function. It also applies to dual-zone climate control configurations for the HVAC recirculation door actuator positions shown in the fitment table.

This part cross-references OE-style numbers such as 9C3Z19E616B and 9C3Z19E616C for the same application. The Four Seasons 73020 is a practical replacement when the original actuator no longer moves the blend or recirculation door correctly.

What It Helps Fix

• Incorrect cabin temperature control
• Airflow stuck on one vent setting
• Recirculation door movement problems
• Blend door response issues in the HVAC system
• Clicking or inconsistent actuator operation

Installation Notes and Tips

Verify the connector style, terminal count, mounting ear layout, and door linkage before installation. Confirm the position shown in the fitment data matches your vehicle’s HVAC location: Main, Left Main, or Right Main. On 2010 Ford F-250 Super Duty and 2010 Ford F-350 Super Duty models, match the actuator to manual HVAC control or dual-zone climate control recirculation door applications as listed.
