I'm sorry to hear about the issue you're experiencing with the temperature blend door in your vehicle's HVAC system. From your description, it seems that the actuator replacement did not resolve the problem. Here are a few additional steps you can take to further diagnose and potentially solve the issue:
Verify actuator installation: Double-check that the actuator is correctly installed and securely connected to the blend door. Ensure that the actuator's linkage is properly aligned with the blend door's linkage. It's possible that the actuator may not be properly engaging with the blend door, preventing it from moving.
Test actuator functionality: With the actuator installed, disconnect the actuator's electrical connector while the vehicle is running and the HVAC system is on. Then, manually change the temperature setting on the control panel. Listen for any clicking or movement from the actuator. If you hear and observe the actuator moving, it could indicate that the issue lies elsewhere in the HVAC system, such as the blend door itself or the control module.
Inspect blend door operation: If the actuator is functioning properly, it's important to check the blend door's movement directly. Remove the actuator again and manually move the blend door by hand while changing the temperature setting on the control panel. Ensure that the blend door moves freely without any obstructions or restrictions. If the blend door is difficult to move or stuck in one position, there may be an issue with the blend door itself or its linkage.
Check HVAC control module: If the blend door moves smoothly and the actuator is functioning correctly, there could be an issue with the HVAC control module. The control module is responsible for sending the signals to the actuator to control the temperature blend door. It may be necessary to have the control module tested or replaced if it is determined to be the source of the problem.
