Hello my name is***** am an ASE Master Technician and I am glad to help you out with your question.

Expert:  Dan replied 4 months ago.

It is common for a mode door actuator to cause this problem. I have also seen the mode door break in the housing, so replacing just the actuator will not always work. You need to verify the problem.

REMOVAL

WARNING: Disable the airbag system before attempting any steering wheel, steering column or instrument panel component diagnosis or service. Disconnect and isolate the negative battery (ground) cable. Wait two minutes for the airbag system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the airbag system. Failure to follow these instructions may result in possible serious or fatal injury.

NOTE: The heating-A/C system is equipped with two mode door actuators, one for the panel/floor-air door and one for the defrost-air door.

NOTE: Illustrations shown with instrument panel removed for clarity.

I don't want to tear into the dash, etc. I just wanted to know, before I take the truck to the dealership or another mechanic, I'd there anything simple that could cause this that I could check myself real easily? Like, could a fuse cause this? Could a door just be stuck and if I reached into that part maybe I could jostle it loose? Anything I can try before I take it to mechanic?
Expert:  Dan replied 4 months ago.

Not a fuse. The hvac control module controls the mode actuator.

Disconnect both battery cables (positive and negative) and hold them together for 15 minutes. Then reconnect one at a time, positive first then negative. This should reset the system.
