Hello. My name is ***** ***** I'm here to assist you.

It is likely your actuator defaulted to defrost or heat. You'll simply need to move the blend door into the correct position to match your new actuator, as the actuator was manufactured in a different position than your door is currently positioned in. The doors should move freely. I'll attach the actuator recalibration procedure.

Alternate Method (w/o Scan Tool)

  1. Clear all DTCs.
  2. Place the ignition switch to the OFF position.
  3. Install the HVAC control module or HVAC actuator.
  4. Connect all previously disconnected components.
  5. Remove the HVAC/ECAS fuse for a minimum of 10 seconds.
  6. Install the HVAC/ECAS fuse.
  7. Start the vehicle.
  8. Wait 40 seconds for the HVAC control module to self-calibrate.
  9. Verify that no DTCs have set as current DTCs.

You can also slide the actuator onto the shaft loosely and then turn the whole actuator assembly for leverage to turn the door to line up the screws.
