More than likely this is a blend door issue if you have already changed the control module.

Sometimes these things start losing their place and will move around to where they want to go. Do you hear any clicking or clunking when the temperature changes?

To confirm this we need to remove the actuator and check the voltage when this is acting up. If the voltage is remaining consistent then the actuator is the issue.

Below is the process from the manual that will help with checking and changing this if it proves out. Let me know if you have questions. Thanks
