If it speeds up with the fan speed, it isn't an actuator. It seems something is touching the fan blade. An actuator wouldn't respond like this.
The fan could be loose, the blade could be loose, something could have gotten into the blower motor box, or even a mouse could have gotten into it.
Also, there is a cabin air filter in this vehicle. It should be behind the glove box. Remove the filter and see if there is excessive dirt or anything in it.
The cabin air filter is located under the glove box. I found a picture and circled where it will be located. There is a plastic cover that clips on. Remove the cover to access the filter. (See pic 1)
If the filter is clean and doesn't indicate any excessive debris, I need you to remove the blower motor to check if something is lose or in the box. If you look at pics 2 and 3 below, they are the directions for the removal of the blower motor.
Let me know what you find or if you have other questions.
Take care,
Joe
