THIS IS FOR THE DRIVERS SIDE BLOWING OUT HOT AIR INSTEAD OF COLD AIR. 
[Idk if its the same for the passenger side]

This video is to find out of if the actuator thats blown or something else. 


The foot black plastic protector has 4screws, 7mm socket size.

The actuator has 2 screws, 5.5mm socket.

When you start the truck and turn on the ac. Put it on cold first, and let it cool in about 3mins. After, turn the little swivel right, left and it'll start blowing hot air. 
[Right for cold....Left for heat]

This is the best way to know if its the actuator or not. (That I know of)
