Dorman HVAC Blend Door Actuator for Ford Fiesta 2011–2019 — Direct-Fit, Quiet Temperature Control

The Dorman 604-251 HVAC Blend Door Actuator is a direct-fit replacement part designed to restore proper climate control door movement in compatible Ford Fiesta models from 2011 through 2019.

If the HVAC system in your Ford Fiesta is blowing uneven temperatures, making unusual noises, or failing to switch airflow modes, a worn or failed blend door actuator is often the cause. The Dorman 604-251 is engineered to match the original actuator’s fit and function for specific vehicle configurations, offering a straightforward repair option without modifying the HVAC assembly. Before purchasing, verify the actuator’s position and compatibility using the vehicle application notes or the site’s garage tool to make sure it matches your Fiesta’s trim and actuator location.

How does this actuator restore HVAC performance?

The actuator replaces the motor that moves the HVAC blend door so air mixes correctly between heating and cooling circuits. When installed in the correct position, it returns smooth, quiet door travel and accurate temperature blending. This helps the vents deliver the temperature you select from the control panel.

• Direct replacement engineered to match original mounting points and connector
• Restores blend door movement to correct hot/cold mixing
• Reduces clicking or grinding noises from a failing actuator
• Designed to work with the original vehicle wiring and controls

Which vehicles and actuator positions does the 604-251 fit?

The 604-251 is manufactured to fit specified Ford Fiesta model years and particular actuator locations; it is not universal for all positions. Many vehicles use several different actuators for mode, recirculation, and blend functions, so confirming the part’s application notes for your trim and year is essential. If the product page shows an information icon, hover or click it to review any additional fitment details.

• Compatible with Ford Fiesta years 2011–2019 (verify trim and position)
• May be position-specific—check application notes before ordering
• Use the site’s garage tool and Confirmed Fit indicator to validate compatibility
• Contact a qualified technician if you’re unsure which actuator to replace

How should I verify fitment before buying?

Confirming fitment prevents receiving an actuator that doesn’t match your vehicle’s HVAC position or connector. Enter your vehicle details into the product’s garage tool and look for a Confirmed Fit message. If a blue information icon appears, review the notes for any special trim or position requirements, or consult a technician for guidance.

• Input year, make, model, and trim into the garage tool on the product page
• Check the Confirmed Fit bar and read any information icons carefully
• Review application notes to match actuator position and function
• Ask a qualified service technician if fitment is unclear

Who is this for: The Dorman 604-251 HVAC Blend Door Actuator is intended for DIYers and professional technicians replacing a faulty blend door actuator on compatible Ford Fiesta models (2011–2019).
