The air and heat won’t blow out in the back of the truck. The front is working fine.

This happens when the rear blower motor goes out, but to be sure we should check the fuses (rear HVAC 30 amp) in the interior fuse panel. If it's okay, here are the instructions on how to change the blower motor out in the diagrams below:
