Blend door location..
Open up glove box, empty out all your stuff, on the inside of box on the sides you will see tabs with stoppers. Pull in tabs to clear the stops and the door will drop down. The blend door will be to the top lefthand side, you will see electrical wires going to it. There are 3 or 4 bolts for it, I can't remember!! The one bolt you won't be able to see, you will need to reach up in there and feel for it. If you remove the actuator form the door, be careful not to bump the door to a different position, the door pin needs to line up with the actuator key hole, it only lines up one way. With the actuator off the door and plugged back in you can turn the truck on and use your HVAC controls to see if the actuator is engaging/moving. Remember to turn off the HVAC in the same position so the actuator will line up with the door when you reassemble it.
If you bump the door out of alignment, you can use a small mirror and a flashlight to get the door pin in the right position for the actuator.
If the blend door actuator is working good, you may have issues with the HVAC contols on the dash.
