Hello and welcome to 2CarPros. The blend door(s) and actuator(s) are not your problem here. Their job is to control the temperature of the air coming out, and not where it comes from. What you need to be looking at is the mode door(s) and actuator(s), as that's what's in control of the airflow.
I'm attaching images pulled from Alldata that detail (1) how to pull the HVAC unit (2) how to change the mode door actuator and (3) how to test the actuator. By the images, it may look like a daunting task, but it's actually not bad. Just follow it step by step, reading each instruction at least twice, and go through the processes.
Let us know what you come up with. If you have more questions, please respond to this thread. Thanks for using 2CarPros and good luck!
