You need to replace your cab filters. So do I but do not know how to remove them. They are bewing the glove compartment. I've taken out 3 screws and 4 8mm bolts. Can pry top and bottom apart a little and see them but havn't been abel to remove them yet.
I would change transmission fluid and differential fluids. check to see if it has a fuel filter also I know they stopped putting an inline filter somewhere around your year model and just has one in tank that doesnt have to be changed. you can also change air filter and inside cabin air filter located behind glove box . The spark plugs are platinum good for 100,000 then tune up needs to be done. plugs and wires, use only ac delco platinum plugs and ac delco wires. a little more expensive but way better to me than the others. they have coil packs so there is no distributor cap or button to replace.
there is a vent opening linkage for the top vents if you had removed panel for sterio install this linkage might have come loose or the wiren to electric relay to open top vents came loose
also vent doors on front of a/c vents are turned to the closed position
also quite possible the passenger blower motor compartment door in side the blower mode has something blocking entrance
also your truck might be equiped with a blower motor filter i read that these need to be changed out during normal filter replacements the filters for ford i didnt know they started using filters for a/c on reading this since 2000
