Dorman HVAC Blend Door Actuator for Ford & Lincoln - 604-288 Direct-Fit, Blend/Temperature Control

The Dorman 604-288 HVAC blend door actuator is a direct-fit replacement part engineered to restore proper airflow blending and temperature control in compatible Ford and Lincoln vehicles.

If your vehicle’s cabin temperature won’t change, vents blow inconsistent air, or you hear clicking from the dash, a failed blend door actuator could be the cause. The Dorman 604-288 is built to match the original equipment’s fit and function for specific model years and configurations, offering a straightforward swap when the failed actuator controls the blend (air temperature) door in the HVAC box.

Which vehicles and years is this actuator compatible with?

The 604-288 fits a range of Ford and Lincoln trucks and SUVs across multiple model years, but it is position-specific—many vehicles use several different actuators. Confirm fitment by selecting your exact make, model and trim in the vehicle lookup or review the application notes for your VIN and actuator location.

• Common fits include Ford F-150 (2015–2023), Ford Super Duty models (F-250 to F-550, select years), Ford Expedition and Lincoln Navigator (2018–2023).
• Also compatible with Ford F-150 Lightning (2022–2023) and Ford Lobo across similar years.
• Always verify the actuator’s position (blend/air door) matches the part you need.

How does this replacement restore HVAC function?

This actuator replicates the original part’s motion and electrical connection to move the internal blend door that mixes hot and cold air. Restoring that movement returns accurate cabin temperature control and smooth vent operation without electrical faults or erratic movement.

• Direct-fit gearing and mounting points align with factory locations for easy installation.
• Electrical connector matches OEM pin configuration for plug-and-play replacement.
• Durable motor and gears reduce risk of premature failure or burnout.

What should I check before ordering and installing?

Because many vehicles have multiple actuators, identify which door (mode, blend, or recirculation) is failing and confirm the part’s application notes. Use the garage tool or consult a trusted technician if you’re unsure which position you need.

• Input your vehicle’s make, model, year and trim into the fitment tool before purchase.
• Inspect the part number and connector shape against your original actuator.
• If unsure which actuator is bad, diagnose by observing vent behavior and listening for clicking near the HVAC box.

What are the built features and quality assurances?

Dorman designs replacement components to meet strict standards for mechanical fit and electrical performance, with attention to long service life and resistance to wear. This actuator is engineered and tested to help withstand typical HVAC stresses and to meet expectations for longevity and reliability.

• Constructed with robust gearing and motor components to reduce wear.
• Electrical insulation and connector durability to limit burnout risks.
• Backed by Dorman engineering and a history of parts design for aftermarket reliability.

Who is this for? The Dorman 604-288 is intended for vehicle owners, DIY mechanics and professional technicians who need a position-specific, direct replacement blend door actuator for compatible Ford and Lincoln models. It’s a practical choice when the original actuator is noisy, non-responsive, or causing incorrect cabin temperatures, provided you confirm the actuator’s position and fit for your vehicle before purchase.
