I have replaced the mode door actuator, and I also replaced the control unit. Everything has power and is working like it supposed to but it won't switch from defrost mode. Do I just need to pull the fuse and let it re calibrate itself?

Yep, that will help reset the system, here is the location of the fuse to help you. Here is the location of the mode actuator so we can be on the same page. With the key on remove the fuse for 90 seconds. Check out the images (below). Please let us know what happens.
