  • Direct replacement: engineered to install like the original air door actuator on the listed applications and get the HVAC blend door moving again.
  • Position specific (MAIN): many vehicles use several door actuators for different positions and functions, so review the application notes to confirm this MAIN actuator matches the one you need to replace.
