Detailed Description

Dorman 604-918 is an HVAC heater blend door actuator built for specific 1995-2002 Ford and Mercury vehicles. It controls the blend door position that regulates how heated and cooled air is mixed before entering the cabin, helping maintain accurate temperature output from the HVAC system. This part cross-references F5RZ19E616A and SK604918 for the same application. Use 604-918 when replacing a worn or nonresponsive actuator in a 1995-2000 Ford Contour, 1995-2000 Mercury Mystique, or 1999-2002 Mercury Cougar, Main position.

What It Helps Fix

  • Inconsistent cabin temperature control
  • Air stuck on hot or cold
  • Blend door movement that does not respond correctly
  • HVAC temperature changes that are delayed or erratic
  • Actuator noise from a failing internal motor or gear set

Installation Notes and Tips

Verify the vehicle year, make, model, and Main position before ordering. Compare the original actuator connector, mounting points, and rotary-style operation to confirm match-up with the existing HVAC system. After installation, cycle the ignition and HVAC controls to allow the actuator to relearn its position if required by the vehicle.
