Dorman HVAC Blend Door Actuator 604-214 for Ford Lincoln Mercury — Direct-Fit, Durable Replacement

The Dorman 604-214 HVAC blend door actuator is a direct-fit replacement part designed to restore proper heating, ventilation and air conditioning airflow control in compatible Ford, Lincoln and Mercury vehicles.

If the temperature inside your car isn’t matching the selector or you hear a clicking or grinding noise coming from the dash when you change modes, a worn or failed blend door actuator is often the cause. The Dorman 604-214 replaces the factory actuator for specific model years and configurations and is built to the same dimensions and electrical interfaces as the original so it installs in the same mounting location and connects to the same harness.

How will this actuator fix my HVAC temperature issues?

When the blend door actuator fails, the HVAC blend door can stick or stop moving, preventing proper mixing of hot and cold air. Replacing the faulty actuator with a direct-fit unit like the Dorman 604-214 returns control of the blend door to the vehicle’s HVAC controls, helping to restore the intended cabin temperature range.

• Direct replacement engineered to match original fit and function

• Reduces or eliminates clicking, grinding or loss-of-control symptoms

Which vehicles and positions does the 604-214 support?

This actuator fits specific Ford, Lincoln and Mercury models across several years; many vehicles have multiple actuators, so position and function must match. Always verify fit by entering your vehicle trim into the garage/fitment tool or by checking the application notes before purchase.
