Default air conditioner problem

not sure where to post this. i have a 1998 ranger xlt 4.0 ohv 5 speed. runs great! when i put it on max a/c it blows out cool air but not as cool as it should be. i am pretty sure that it needs a little charge of freeon. gonna do that soon. the problem is that when i put it on regular a/c it blows out hot air. i mean hot air from the heater core. i replaced the little black panel that has the 3 knobs (to select the air mode, temperature, and fan speed). this didnt change anything.

all the vacuum lines look good- no cracks or leaks that i know of. the valve in the heater lines works as it should. the truck has 104k miles. every thing is original.

the previous owner smoked in it a lot. im guessing that one of the doors in the duct work in the dash is broken? or whatever moves it isnt working?

i am out of ideas so any help will be appreciated. thanks!

The blend door is broken. The fail to full heat. Google or search here for Blend Door. When you put it to Max AC, it shuts a valve on the hot water to the heater core.
